What programming languages are necessary to work as a backend engineer in Japan? In addition to programming languages, being able to use frameworks will also expand the scope of your work. In this article, we will explain the programming languages and frameworks necessary to work as a backend engineer in Japan, as well as knowledge outside of the language.If you would like to work as a backend engineer in Japan, please use IT industry global company recruitment agency “G Talent”.What is a Back-end Engineer?First of all, let's take a look at what a back-end engineer actually is.The difference between front-end and back-end engineersBefore explaining what front-end and back-end engineers are, we need to explain what the front-end and back-end of a system are. A system is divided into a front-end for the user and a back-end for the server, and the engineers in charge of each are different.The screens that users see on websites and web apps are displayed by the front-end system, which is made using HTML/CSS, JavaScript, etc. The front-end system displays screens, sends input information to the server-side system, and achieves other screen transitions.On the other hand, the system on the server side is called the back-end, and is made using PHP, Java, etc. The program processes the information entered on the front end, accesses the database as necessary, and returns the results to the front end.Back-end engineers are those who develop the programs on the back end, while front-end engineers develop the programs on the front end.Reference: フロントエンドとバックエンド：役割とスキルの違いを解説／TECH PLAYBack-end engineers have a promising futureBack-end engineers have a promising future. The IT market, and web content in particular, is continuing to grow, and back-end engineers are indispensable to web content. For this reason, it is predicted that demand for back-end engineers will continue to grow in the future.In addition, there are many existing systems, and there is plenty of work to be done, such as adding functions, maintenance, and migration to new systems. In this way, it can be said that back-end engineers have a promising future.Reference: バックエンドエンジニアは今後どうなる？将来性やキャリアパスを解説！／HiPro TechWhat programming languages are in demand for back-end engineer in Japan?The following eight programming languages are in demand for backend engineers at IT companies in Japan.PythonPHPRubyC++PerlJavaGoSQLPythonPython is a programming language that is used in fields such as AI, big data, machine learning, and IoT. For this reason, if you are thinking of changing jobs to work in a field that deals with AI or machine learning, we recommend that you learn it. It is a general-purpose language that can also be used to develop web apps, games, desktop apps, etc.In addition, Python is characterized by its small code and easy-to-understand code. For this reason, it is one of the most popular languages, as it is less likely to cause bugs.Reference: 【入門】Pythonとは｜活用事例やメリット、できること、学習方法を解説／スキルアップAI JournalPHPPHP is one of the languages that is frequently used in web-based development. It can be used for web app development, EC site construction, and other development, so if you want to work as a web-based engineer, we recommend that you learn it.PHP is a scripting language that is embedded in HTML. It has the characteristics of being simple and easy to understand, and is also easy for beginners to learn.In addition, WordPress, which is a leading CMS, is developed using PHP. Since you can customize WordPress using PHP, it is a good idea to learn it if you want to find a job or change jobs in a field that uses WordPress frequently.Reference: PHPとは？基礎知識、できることを初心者にもわかりやすく解説します／カゴヤのサーバー研究室RubyRuby is a language that is easy for beginners to learn, and is a very good language that is designed so that anyone who writes it will end up with similar code. It is used in the development of many websites, and will continue to play an active role in the future.One of the major advantages of developing in Ruby is that it produces simple code, so bugs are less likely to occur. And the biggest advantage is that there is an excellent framework called Ruby on Rails.If you can make use of this framework, you will be able to mass-produce high-quality code efficiently. If you want to work as a back-end engineer in a workplace that uses Ruby, you can say that learning Ruby on Rails is essential.Reference: プログラミング言語のRubyとは？特徴やできることを解説／発注ラウンジC++C++ is an object-oriented language that extends the C language, and it is used in a wide range of fields, including web apps, embedded systems, AI development, and game development. It is an old language, but it is still in use, so if you learn it, you will be able to get work such as specification changes and maintenance.Reference: C++とは？今さら聞けない基礎から応用までを解説／発注ラウンジPerlPerl is a programming language that has been used for a long time. It is an easy-to-use language that has been used mainly in the fields of web development and server management. There are still many systems that run on Perl, so there will probably be a lot of work in the future, such as specification changes, adding functions, and maintenance.JavaJava is an excellent language with a long history that is used in a wide range of fields. It is often used in existing systems, so there will probably be a lot of work in the future, such as adding functions, changing specifications, and maintenance. However, as it is not the latest language, you will also need to learn new technologies and languages in parallel.Java is a language that is used in a very wide range of fields, and it can be used to develop web apps, PC apps, Android apps, CG development, embedded systems, etc. Java has the advantage of being able to build highly secure and robust systems, and it can reduce bugs and security risks.It is important to remember that JavaScript is completely different from Java. Java is a general-purpose language for back-end development, while JavaScript is a language used to build dynamic screen controls for web page development. Please be careful, as they are completely different languages, like “as different as melon and melon bread” or “as different as India and Indonesia”.Reference: 【入門】Javaとは？言語の特徴やプログラミングの流れをわかりやすく解説！／Engineer LaboGoGo is a new language that is expected to play an active role in the future, developed by Google in 2009. Go has the advantage of being able to be developed compactly with a small amount of code, and bugs can be kept to a minimum.For this reason, it is a language that makes it easy to develop high-quality programs efficiently. However, because the grammar is completely different from other languages, there is the disadvantage that it takes time to learn if you are learning it from scratch.Reference: Go言語とはどんなプログラミング言語？特徴やできることを解説／発注ラウンジSQLSQL is a very old language, but it is a language that is still in active use today and will continue to be used in the future for database construction and operation. It is used in database management systems such as MySQL, MariaDB, and SQLite.Back-end engineers are almost always involved in database environment construction and processing program development. For this reason, it is a language that must be learned.What frameworks are required for back-end engineer in Japan?A framework is a collection of already-written code, and it contains code for frequently-used functions. By using a framework, you can develop efficiently and with high quality. The frameworks used by Japanese companies are as follows.CakePHPGit/GithubRuby on RailsDjangoLaravelFlaskCakePHPThis is a framework that is often used in PHP, and it has many functions that are useful for developing web pages and web apps.

We recommend that PHP developers learn it as a priority.FlaskIt is a Python web application framework. Its features include a lightweight framework that is easy to learn and highly customizable. We recommend learning it in conjunction with Django.What knowledge is required for back-end engineer in Japan?If you want to become a backend engineer in Japan, you will also need knowledge other than programming languages and frameworks. From here, we will explain the knowledge required for a backend engineer.Knowledge of how the internet worksKnowledge of operating systemsKnowledge of servers and databasesKnowledge of securityKnowledge of how the internet worksYou will need knowledge of how the internet works, how to set up devices, and security. As systems move to the cloud, there is no doubt that engineers who can handle the internet safely and efficiently are in strong demand.Reference: バックエンドエンジニアの学習方法とは？スキルや言語について徹底解説／パーソルクロステクノロジーKnowledge of operating systemsBackend engineers need to be able to build systems that work with a variety of operating systems and environments. In addition, there are many cases where you will need to adapt to a variety of environments, as there is no guarantee that there will be just one type of development environment or client-side environment. For this reason, knowledge of operating systems is also necessary.Knowledge of servers and databasesBack-end engineers need to become specialists in servers and databases in order to build servers and databases. For this reason, they will need to have knowledge of various server and database environments. In addition to being able to develop in the environment they are working in, they will also need to have the skills and knowledge to build development environments, change settings, and perform maintenance.Reference: バックエンドエンジニアになるには（身につけるべき重要なスキル）／kinstaKnowledge of securityThe use of the internet is expected to continue to increase in the future, with the cloud using online resources, users using the internet, and remote control of home appliances through IoT. As a result, measures to prevent security risks such as unauthorized access by third parties, identity theft, and information leaks will become increasingly important. When developing a system, you will need knowledge to develop a system that takes security risks into account.If you are looking for a job as a back-end engineer in Japan, we recommend “G Talent”In this article, we have explained the programming languages and frameworks you need to work as a backend engineer in Japan, as well as knowledge other than languages.

In order to work as a front-end engineer at a Japanese company, it is necessary to learn the programming languages that are in demand at Japanese companies. In addition to development languages, it is also useful to know the knowledge that is useful when working in Japan, and this will make your job-hunting activities as an engineer in demand in Japan smoother.In this article, we will explain the development languages and frameworks that are in demand at Japanese companies, as well as the knowledge you need to know in order to work in Japan. If you are looking for a job that suits you in Japan, we recommend using “G Talent”, a recruitment agency that brings together global companies in the IT industry.Front-end development languages in demand at Japanese companiesThe following three languages are in demand and should be learned in order to work as a front-end engineer at a Japanese company.HTMLCSSJavaScriptHTMLHTML is a language that is essential for web development, so you should definitely learn it if you want to work as a front-end engineer, not just for Japanese companies. The latest version of HTML is HTML5.It is a language that is necessary for creating the composition of text and images on web pages, and front-end engineers in web development always use it. Even if you don't actually do the coding, there are cases where you need to know HTML, such as when you need to verify or improve the content by looking at the source of the screen. It is one of the languages that are indispensable for front-end development.Reference: フロントエンジニアに必要な言語とは？フレームワークやライブラリについてもご紹介／パーソルクロステクノロジーCSSCSS, also known as a style sheet, is a language used in conjunction with HTML. It is necessary for specifying font and color, etc., and for front-end engineers who must master HTML, it is also essential to master CSS.Even if you are not actually developing the source, you may also need to look at the source if you are involved in website development or web app development. For this reason, it is recommended that you familiarize yourself with its structure and syntax. Along with HTML, it is a language that is in demand for web development.Reference: フロントエンド言語とは？フレームワークやライブラリについても解説／トライコーンラボJavaScriptJavaScript is a language for developing dynamic web page movements. In recent years, there has been an increase in the number of websites and web apps with complex, screen-based movements, so JavaScript can be said to be a skill that is essential for front-end engineers.As the need for JavaScript continues to evolve, languages that extend JavaScript and are upwardly compatible, such as TypeScript, have also appeared. By acquiring the knowledge to develop advanced screens, you can become a front-end engineer who can work in Japanese companies.Reference: JSが苦手なフロントエンドエンジニアが語る 「JavaScriptと仲良くなるための基本の「き」」／PLAN-BFront-end languages you want to learn to become an engineer in demandThe front-end development languages that Japanese companies need, as mentioned above, are all basic ones. It is only natural to know these languages, and in order to be an engineer in demand at a Japanese company, it is necessary to master an advanced, upwardly compatible language.One such upwardly compatible language that front-end engineers should master is TypeScript. TypeScript is an extension of JavaScript developed by Microsoft. It is a type language that performs type declarations, and has the advantage of being able to prevent errors at the time of compiling the source. For this reason, it is characterized by being able to suppress the occurrence of bugs compared to JavaScript, and being able to develop efficiently.Currently, more and more companies are switching to TypeScript, which allows them to develop JavaScript code more safely. If you learn TypeScript as a front-end engineer, you will be able to handle more work and become an engineer in demand.Reference: フロントエンドの開発で必要な言語一覧！JavaScriptだけでなくTypeScriptのスキルも必要？／転職GUIDEIf you want to master front-end development, framework skills are also importantIn order to master front-end development in Japan, you need to learn not only languages but also frameworks. A framework is a collection of already-made source code.For example, login authentication and payment functions are often used in web development, and frameworks play a role in organizing these functions in a way that makes them easy to reuse. If you use a framework that has already been created, you can develop more efficiently.Since frameworks already have quality assurance, if you use them well, you can develop high-quality programs quickly. From here, we will introduce five frameworks that are in demand in front-end development.jQueryReact.jsVue.jsAngularJSBootstrapjQueryjQuery is a JavaScript library. A library has a similar role to a framework, and while a framework is a framework, a library can be used as a component in parts.If you use jQuery, you can easily implement code for web browsers, and it is designed to be easy for beginners to use. It is used in many web production environments, so if you want to work as a front-end engineer at a Japanese company, you should learn it.However, while it makes it easy to implement things like animations, it also has the disadvantage of being slow. Since many functions have been added since it was first released, be aware that it may be slow and difficult to use in some cases.Reference: jQueryは終わったのか論争を、終わらせにきました。／TOMORROW GATEReact.jsReact.js is a JavaScript library similar to jQuery. It is a library developed by Facebook and its community, and is mainly used to build UI components. It is used by many Japanese companies, so if you want to work as a front-end engineer at a Japanese company, it is recommended that you learn it.It is designed to make it easy to manage the source code, and is suitable for large-scale development, which tends to have a complex design. However, since many of the documents are in English, you will need a high level of English ability to gather the information you need. In that respect, it is a library that is easy for foreign engineers to use.Reference: React.jsとは？基本情報からメリットに至るまで詳しく紹介／発注ラウンジVue.jsVue.js is one of the JavaScript frameworks for building UIs. It was designed based on the concept of a progressive framework, and it has the feature of being easy to use even when the system is gradually added to with functions at a later stage.Once a web system has been developed, it doesn't end there - there are often times when functions are added to respond to the requests of clients and end users. In such cases, the framework introduced at the beginning of development may not be able to handle everything, but Vue.js can be extended without any problems. This is made possible by the concept of a progressive framework.Reference: Vue.jsについて学習してみた ＜基礎編＞／ラクスエンジニアブログAngularJSAngularJS is a Model-View-Whatever (MVW) framework developed by Google and its community. Using AngularJS allows you to efficiently develop the front end of complex web applications. It is a framework that is particularly suitable for business applications and CRUD applications.BootstrapBootstrap is a web framework that is made up of HTML/CSS and JavaScript. It includes commonly used functions such as forms and buttons, and is also characterized by the fact that it includes website design templates. By using Bootstrap, you will be able to build a website with a high level of design, even if you don't have programming languages such as HTML/CSS or JavaScript, or design skills.There are several types of Bootstrap, including one that can be used in conjunction with AngularJS and one that has been developed for WordPress. We recommend that you learn the type that is most appropriate for the type of Japanese company you are working for.Reference: Web用フレームワーク「Bootstrap」について徹底解説／R-StoneThree types of knowledge other than the languages required for front-end developmentIn order to work as a front-end engineer at a Japanese company, it is not enough to have knowledge of programming languages, frameworks, and libraries. Here, we will explain the knowledge that will be useful to acquire in addition to languages.Knowledge of UI / UX designKnowledge of web marketing (SEO)Knowledge of back-end engineersIf you acquire knowledge that is useful for these jobs, as well as development languages and frameworks, you will be able to smoothly enter the development field after changing jobs.Knowledge of UI/UX designYou can't develop a website that is easy for users to use just by being able to build websites using HTML/CSS and JavaScript. You also need UI design skills to build designs that are easy for users to use, and UX design skills to improve users' customer experience. If you study both of these in depth, they will definitely be useful as a front-end engineer.However, it may be difficult to directly apply your knowledge and skills to your work if you only study them. You will gain practical skills by gaining knowledge and skills and gaining work experience. It is important to continue to hone your UI and UX skills even after you have found a job or changed jobs.Also, these days, websites and web apps are not only viewed on computers, but are increasingly being used on a variety of devices such as tablets and smartphones. For this reason, it is important to be aware of and acquire knowledge of “responsive design”, which is design knowledge for supporting a wide range of devices.Reference: レスポンシブWebデザインとは？基本知識から作り方まで詳しく解説！／NIJIBOX BLOGKnowledge of web marketing (SEO)In order to build a website or web app that will be seen by many users, it is not enough to simply improve the content. As web marketing knowledge, you need to know about SEO.SEO is a method of ensuring that your website appears at the top of the search results when people search for keywords on Google, Yahoo! and other search engines. In addition to building a site with excellent content, SEO requires a number of other measures, such as tag composition, the use of appropriate keywords, and link improvements.In order to carry out SEO measures, you need specialist knowledge and you have to carry out a lot of very tedious work. It's very difficult because you don't see immediate results, and even if you do take measures, you can't be sure that you'll get results. By gaining knowledge and experience in SEO measures, you can become an excellent front-end engineer.Reference: 【2024年版】SEOとは？基本と初めにやるべき具体策5つをわかりやすく解説／SATORIKnowledge of back-end engineersIn order to be active as a front-end engineer, you also need knowledge outside of front-end development. The most important thing is knowledge of back-end development, which is carried out alongside front-end development.In order to develop websites and web apps, both the front-end and back-end sides are necessary, and the two systems are ultimately combined and used together. However, if each engineer carries out development without knowing about the other's system, the systems will not combine well.To prevent this from happening, you need engineers who know both the front-end and back-end. If you have an engineer who knows the whole picture of website and web app development, development will progress smoothly.Master the languages for front-end development that are in demand and become an active engineer!In this article, we have explained the development languages and frameworks that are in demand at Japanese companies, as well as the knowledge required. If you can use the front-end development languages, frameworks and libraries that are in demand at Japanese companies, you will be able to make your job-hunting activities more successful. In addition to programming languages, frameworks and libraries, we also recommend that you study other knowledge that will be useful to you.For those looking for jobs as foreign IT engineers, we recommend the foreign IT engineer job change agency “G Talent”.

Such high-functionality screen movements are now being adopted by many websites. For this reason, if you are involved in website development or web app development, it is essential to learn JavaScript.Reference: フロントエンドエンジニアに必用な言語4選 | フレームワーク・ライブラリなどもご紹介／R-StoneC, C++C is a programming language that has been used for a long time and is often the first language to be learned. It is used for a wide range of development, including operating systems, core systems, software, and embedded systems. On the other hand, C++ is an object-oriented language that extends the C language. It can be used for web apps, embedded systems, AI development, game development, etc.Although neither of these languages is the latest, there are still many systems in Japan that are still running on C or C++. There is a lot of demand for maintenance of existing systems and for changing specifications, etc., so if you want to be a successful programmer, it is a language you should know.Reference: C++という言語について／HITECHSJavaJava is a language with a long history that is used in a wide range of fields and is related to existing systems, so it is a language that programmers should learn as a priority. There are many existing systems that have been developed in Java, so if you want to work as a programmer or IT engineer, you should learn it. However, as it is not the latest language, you will probably need to learn new technologies and languages other than Java in the future.Java is used in a wide range of fields, including web apps, Android apps, PC apps, CG development, and embedded systems. Java is a highly secure language that minimizes bugs and security risks, and it is also attractive because you can use frameworks such as Spring and Spring Boot to code efficiently.C#C# is a language developed by Microsoft that is used for web apps, smartphone apps, game development, etc. It is highly versatile, so there are many situations where it will be useful if you learn it. Note that it is not related to C or C++, although the names are very similar. Although it is not the latest language, there are many existing systems that are running on C#, so it is recommended that you learn it if you are going to do the above jobs.HTML, CSSHTML and CSS are essential development languages for website and web app development. HTML is used to create the structure of web pages and determine the placement of text, images, etc., while CSS, also known as a style sheet, is used to set the color of text, font size, etc. When using these languages, you will need to learn HTML and CSS as a set. These are essential languages for web engineers, so be sure to learn them.Reference: CSSとは？ – HTMLとセットで覚えよう！-／Cyber BridgePHPPHP is a language that is often used in web development, and is used in the development of web applications, EC sites, etc. WordPress, a leading CMS, is developed using PHP, so if you work for a company that uses WordPress, it is essential that you learn PHP.There are many existing systems that have been developed using PHP, and demand for this language is expected to continue in the future for tasks such as changing the specifications of existing systems and maintenance. As it is not the latest language, it is thought that it will give way to new languages in the future, but as it is used in many situations, it is useful to learn it.RubyRuby, which is used in the development of many websites, is an easy language to learn for beginners, and it is expected to continue to play an active role in the future. Ruby is designed so that the code will be the same no matter who writes it, so it has the advantage of being less prone to bugs. It is also characterized by its ease of programming, thanks to the excellent framework known as Ruby on Rails.In order to carry out development efficiently, you should also learn Ruby on Rails as a set. Ruby is still continuing to evolve, so it is one of the languages that engineers should learn. In particular, it is often adopted by venture companies, so it can be said that it is a language that is essential if you are aiming for a job at a venture company.Reference: Rubyの将来性と需要は？懸念されている点も解説／レバテックキャリア5 languages that are expected to be in demand in Japan in the futureFrom here, we will introduce languages that are expected to become increasingly in demand in Japan.

In order to be successful as a project manager at an IT company in Japan, you need to be familiar with the way project management is often done in Japan. Knowing how work is often done in Japan will make it easier to participate in projects, so it's a good idea to familiarize yourself with the flow and methods beforehand.In this article, we will explain the typical project management methods and techniques used in Japanese IT companies, as well as some tips for succeeding in project management in Japan. If you would like to work in project management in Japan, please use IT-related global recruitment agency “G Talent”.What is project management?In IT company project management, the following are the main things that need to be managed.BudgetSchedule and tasksAttendance of project membersIssuesSystem qualityIn addition to managing the budget, schedule and members of a project, the project manager also manages issues and system quality. The main role of the project manager is to manage the project appropriately in all aspects and lead it to success.Reference: プロジェクト管理基本のやり方／ShelterThe flow and methods of project management commonly used in Japanese companiesWe will introduce the typical flow and methods of project management in Japanese companies. By understanding the overall flow, you will be able to respond smoothly when you become a project manager.PreparationPlanningManagementClosingPreparationWhen managing a project, it is essential to make preliminary preparations to confirm the delivery date, budget, project goals, etc. You should identify the issues and tasks of the project, and assess the difficulty of the issues, how long it will take to solve them, the nature and difficulty of the tasks, and the skill level of the personnel required. It is difficult to assess the difficulty and issues without past experience or skills, so it is also important to seek the appropriate methods and opinions of experts and experienced people as necessary.Reference: 【新人PM必見】プロジェクト管理の方法とコツ／Lychee RedminePlanningOnce you have identified and carefully examined the issues and tasks, you can work out a schedule by working backwards from the deadline. When carrying out proper project management, it is necessary to create a schedule that allows you to complete the work without overworking yourself.At the same time as the schedule, it is also important to assess how many resources and personnel are needed, and what level of skill is required for the allocated personnel. If there are not enough personnel and the schedule cannot be completed within the planned timeframe, it is necessary to coordinate with other departments to get the necessary personnel to help out. If you are also planning to train junior staff, you will need to consider who you will pair up with, and who will be in charge of training them.Reference: プロジェクト管理に必要な項目と成功のポイントとは？／NotePMManagementOnce the schedule has been decided and the necessary resources have been gathered, the project will be launched and the project manager will manage the entire project. After the project has started, it is necessary to receive progress reports from the members at regular progress meetings, and to have them report promptly if any problems arise in the methods or results, etc.If manufacturing and testing have started and you receive reports on a daily basis, you may also receive reports on the progress of manufacturing and testing, the number of bugs that have occurred, etc. at the progress meeting. In addition to progress reports, it is also important to communicate closely with project members and be in a position where you can consult with them immediately about even small matters.In many projects, it is common for some kind of problem to occur. It is necessary to have a system in place where the project manager is always aware of the situation and can deal with any problems as soon as they arise.Reference: 進捗会議で何を話すのか／サル先生のプロジェクト管理入門ClosingOnce the delivery is complete and all the steps in the schedule have been completed, the project is closed. Closing is the process of reviewing the project content and results and compiling information to be used in future projects. The project manager analyzes the causes of any deviations from the original plan, why these deviations occurred, what went well and what did not, and summarizes the results. For the next project, it is also necessary to summarize the areas that should be reflected on and the areas that should be utilized in the next project.Reference: プロジェクトや工程終了時に行う７つのポイント – プロジェクト・フェーズ終結／プロマネ研究室Common Project Management Methods in JapanFrom here, we will introduce some of the specific methods of project management commonly used by Japanese companies. By becoming familiar with the methods introduced here, you can reduce the chances of being confused when managing projects for the first time at a Japanese company.Gantt chartWBS (work breakdown structure)CCPMWaterfall developmentPERT diagramAgile developmentGantt chartThe Gantt chart is the oldest method of project management. It is managed in a format similar to Excel, with tasks lined up in order from the top row, and the number of days passes as the columns move to the right.A bar is set for each task, with the left edge being the start date of the task and the right edge being the completion date. The upper and lower bars are divided into the planned and actual, and as progress is made, the actual fills in.The tasks are arranged in a staircase-like pattern, and it is easy to see at a glance how much the planned and actual progress deviate from each other. However, there are also disadvantages, such as it being difficult to understand the relationship between tasks and it being difficult to respond to major schedule changes.Reference: ガントチャートって何ですか？／ITmediaWBS (Work Breakdown Structure)WBS (Work Breakdown Structure) is a method of breaking down tasks into smaller tasks and creating a schedule for them. For example, in the testing process, it is necessary to set the perspective, identify items, prepare for reviews and testing environments, create test data, conduct tests, and check the results. Once the necessary tasks have been identified, the schedule for the tasks is decided and implemented.By using this method, you can identify what needs to be done to reach the goal and how much work will be involved. However, it also has some disadvantages, such as being subjective and making it difficult to break down tasks.Reference: WBS（作業分解構造図）とは？ガントチャートとの違いや作り方を基礎から解説／マイナビクリエイターCCPMThis method, known as Critical Chain Project Management, is often used for large-scale projects, and is a method of minimizing tasks and budgets and allowing for a buffer in the schedule.It is said that when deadlines for work are set, people often do not start work until the very last minute, so by setting a deadline with a buffer rather than a true deadline, you can eliminate waste and shorten the schedule. However, if an inexperienced manager uses this method, they may end up taking too much of a buffer and creating an unrealistic schedule, so it is a method for experienced managers.Reference: CCPM（クリティカルチェーン・プロジェクトマネジメント）とは？大型プロジェクトにはCCPMを取り入れよう／株式会社システムイングレータWaterfall developmentWaterfall development is a method of arranging processes in order, like the flow of water, and has been used for a long time. For example, the project schedule is made up of the following stages: requirements definition, external design, internal design, manufacturing, testing, delivery, and operation.Waterfall development is often used for large-scale projects where the schedule and work content remain largely unchanged. In the case of large-scale systems where functions are added repeatedly, the project stages remain largely the same. If the work process is established, it is easy to make a schedule and to steadily carry out the project.However, it is not suitable for projects where the schedule is difficult to change, where a major problem occurs and the plan goes awry, or for short-term projects.Reference: ウォーターフォール開発とは？メリットとデメリットを解説。ほかの開発手法も紹介！／発注ラウンジPERT DiagramA PERT diagram is a chart that shows the order of tasks and work within a project. PERT diagrams show tasks, work times, work start dates and work end dates, and the order of each task is shown using arrows. It is suitable for complex work orders, such as when work on C can begin after work on A and B is complete, or when work on D and C is not sequential, but work on E cannot begin until C is complete.Reference: PERT 図とは？仕組みや作成方法を徹底解説／asanaAgile developmentAgile development is a method of project management that repeats processes in short periods of time called “iterations”. It is the opposite of waterfall development, where the entire process is decided from the start, and the process is repeated many times.For each iteration, plans and goals are set, and the process is repeated in a short span of time, with the issues and results from each iteration being immediately applied to the next. It is possible to carry out flexible and speedy development while repeatedly changing the specifications. However, it will be difficult to carry out a project without problems using this method unless you have experienced and knowledgeable managers.Reference: アジャイル開発とは？　特徴とメリット・デメリット、スクラムまで徹底解説／Monstarlab Blog5 Tips for Successful Project Management in Japanese CompaniesFrom here, we will explain some tips for successful project management in Japanese companies.Look over the PMBOKUtilize management toolsSetting milestonesCarry out risk managementEmphasize communicationLook over the PMBOKThe PMBOK is a kind of reference book that summarizes knowledge about project management. The PMBOK is the world standard for project management, so it can be used not only in Japan but also in any country where project management is carried out.In some cases, knowledge of the PMBOK is required when hiring a project manager. If you have a good grasp of the PMBOK, it will be useful when carrying out project management work in any country.Reference: PMBOKとは？プロジェクト達成のための世界標準知識を学ぼう／インターネットアカデミーUtilize management toolsTo carry out project management smoothly, let's actively use management tools. We recommend tools that have all the functions a project manager needs, such as progress management, information sharing with team members, file sharing, and attendance management. If you manage manually using Excel or other software, it is easy to make mistakes or forget things, and it will take a long time. Using a management tool can be expected to improve the efficiency of management work.Setting milestonesWhen managing a project, it is important to always be aware of the milestones. Setting detailed milestones, such as checking the direction of the work in progress as well as the deadline for the entire task, can help to prevent delays in progress and also to check the work. Setting specific deadlines for answering questions and submitting materials can also help to prevent them from being neglected.Reference: マイルストーンとは？意味や使い方を解説！中間目標の設定でプロジェクトを成功させる！／JootoマガジンCarry out risk managementRisk management is extremely important for project managers. For example, if the schedule is tight, you will need to take action such as making arrangements to get people from other departments to help out. Be prepared so that you can deal with anything that happens.Reference: プロジェクトにおけるリスク管理とは？手法やプロセスについて解説します／JootoマガジンEmphasize communicationIn order to succeed in project management, it is essential to share information and communicate with team members. It is important to actively communicate with team members, rather than just waiting for them to report.If the atmosphere is such that team members are unable to raise issues, the problems may not be discovered until they have grown in scale, and the damage may be significant. Make sure you communicate with your team on a regular basis so that you can talk to them quickly when they raise their hand.Let's find a Japanese IT company that suits you and work in project management!In this article, we have explained the typical flow of project management in Japanese IT companies, the methods commonly used, and tips for succeeding in project management in Japan. Project management is a very important element for ensuring project success.

There are cases where the way web development is done differs between Japan and other countries. In order to work as an IT engineer in a Japanese company, it will be easier to do your job if you know about the methods and approaches to web development commonly used in Japanese companies, as well as the knowledge and programming languages commonly used in Japanese companies.What are some of the methods commonly used in web development in Japanese companies? In this article, we will explain the common methods of web development used by Japanese companies, the knowledge required, and the programming languages commonly used by Japanese companies. By reading this article, you will be able to obtain the information you need to carry out web development at a Japanese company. If you would like to work as an IT engineer in a Japanese company and be involved in web development, please use the recruitment agency “G Talent”, which brings together global companies in the engineering industry.What is web development?Web development is one of the most common types of engineering work in Japan and around the world, and involves the development of systems such as web services, web apps and web software. Nowadays, it is becoming more common to use web-based systems such as web services and cloud services. Because they are low-cost and highly convenient, there is a growing demand for web-based developers over on-premise systems and software developers.Along with the growing demand for web developers, there is also a growing demand for web engineers in Japan. There is a shortage of IT-related personnel in Japan, including web engineers, and there is also a high demand for foreign web developers. If you are a foreign engineer and you want to work on web development in Japan, it is important to know about the common ways of doing web development in Japan.Reference: Web開発とは？Web開発の流れや必要な準備について解説！／発注ラウンジ[7 Steps] Common web development methods in Japanese companiesFirst of all, we will introduce common web development methods in Japanese companies. There are a total of 7 steps, so let's get to know the general development flow and the content of each step.Requirement definitionExternal designInternal designDevelopmentTestingReleaseOperation and maintenanceRequirement definitionRequirement definition is the process of clearly defining the necessary functions and requirements before starting a project. The website's design, what you want to achieve, what kind of output is needed, etc. are all defined in detail, and a document is created that summarizes these requirements.Once the requirements have been more or less finalized, the necessary budget, personnel, project period, etc. are also decided at this stage. In Japan, it is often the case that a solid plan is made at the beginning of the requirements definition process. For this reason, it is said that the schedule tends to slip and work becomes tight the further along the process goes.Reference: システム開発の「要件定義」とは？進め方やコツを解説／発注ラウンジExternal designExternal design is the system's basic design stage, in which screen design, input/output specifications, etc. are designed based on the functional and performance requirements and constraints, etc. specified in the requirements definition document. In addition to the external design of functional requirements, it is also necessary to design the external design of performance requirements such as the number of users, number of accesses, and response time.The external design is carried out while carefully checking to ensure that there are no omissions in the requirements. If there are omissions at this stage, it will cause major rework later on, so it is important to carry out the work in a reliable way. If a system is created with an incorrect design, it will have to be redone from the design stage, so the design is repeatedly reviewed to ensure that there are no omissions or mistakes.Reference: 外部設計書と内部設計書の違いとは？作成ポイントまで解説！／株式会社システムイングレータInternal designInternal design is the internal design work that is not visible from the outside, such as deciding what language and development environment to use, how to process data, and how to structure the system. It is necessary to clearly define the details, such as the internal operation of the system and the structure of the database. The system must be designed with lean processing and structure so that it can also meet the performance requirements.DevelopmentBased on the external and internal designs, this is the stage where the coding is implemented and the system and programs are developed. High-quality programs must be created while making full use of the programming languages that correspond to the system and programs.In Japanese companies, it is common for development to be outsourced to subcontractors on a module-by-module basis. When outsourcing to subcontractors, it is necessary to hold thorough discussions with the subcontractors to ensure that there are no gaps in understanding. Depending on the subcontractor, there may be differences in approach, so it may be necessary to iron out any differences during the discussions.Reference: WEBシステム開発のプロセス、プログラミング言語、費用などを解説／GALKTestingThe testing process is an essential part of web development. Testing helps to avoid problems and security risks, and also allows you to check that the system has been developed as per the requirements. The testing process is divided into several stages, including unit testing for each module, integration testing where modules are combined, system testing where the system is run from the user's perspective, and operation testing where the system is checked for operation in the actual client environment. It is essential to complete all tests, and bugs are collected as necessary based on the results of the tests.Reference: Webアプリのテスト工程とは？テストの内容と工数について解説／株式会社DesafiosReleaseOnce steps from 1 to 5 have been completed, it is time to release the completed program to the client's system environment. There are three common patterns of release work in Japanese companies: simultaneous migration, where all programs are released at once; sequential migration, where programs are released gradually in stages; and parallel migration, where the old and new systems are run simultaneously for a certain period of time before being gradually switched over. The method used for migration will depend on the system, the content of the program, and the company.Reference: システムリリースを成し遂げるには？／エンジニアの入り口Operation and maintenanceOnce the release has been completed without any problems, the final stage is the operation and maintenance process. The content of operation and maintenance work that is often carried out by Japanese companies includes monitoring to check that the program is running without any problems, daily and monthly maintenance, changing settings as necessary, and dealing with problems. There are also cases where you have to respond to inquiries from end users of the system.Reference: ソフトウェア・システムの「開発」「運用」「保守」の3つの仕事内容とは／Hybrid technologiesKnowledge and skills required for web development, which is common in Japanese companiesThe following three are the knowledge and skills required for web development, which is common in Japanese companies.ProgrammingFrameworksDatabasesProgrammingProgramming is a skill that is required not only when programming in the development process, but also when in charge of the design or testing process. Common ways of using it include when reviewing programs as a designer, or when checking the modified parts of a program when a bug occurs in testing. Of course, advanced programming skills are required when programming. If you have a lot of work experience in the language you are using, you will be able to do a better job.If you have skills such as being able to use advanced development environments and develop tools, you will be in high demand as a web developer. Being able to use advanced development environments has the advantage of being able to speed up compilation and detect program errors. By developing your own tools, you can also automate program checking, automatic debugging, program management, and automatic test data generation.Reference: Web開発とは？Web開発をするために必要なスキルやフローを解説／Geekly MediaFrameworksBy mastering frameworks, you can develop high-quality programs efficiently, so knowledge and skills in frameworks are necessary when programming in the development process.A framework refers to a set of pre-made source code that exists for each programming language. When developing a system, there are common functions that are used in many systems, such as login authentication, input forms, network communication, and payment functions, and by utilizing frameworks that have already been created for such functions, it is possible to efficiently develop high-quality programs.There are frameworks for each programming language, such as Ruby on Rails for Ruby and CakePHP for PHP. If you learn the framework for the programming language you use in the workplace, you will be able to program at a high quality.Reference: フレームワークとは？概要やプログラミング言語別の機能を分かりやすく解説／レバテックルーキーDatabasesIn order to be active in web development at a Japanese company, you will also need knowledge and skills related to databases. In almost all cases, databases are used in any system. You will need to design and develop databases that store data such as customer data and transaction histories, and make them easy to access. Along with programming languages, you should also acquire the skills to develop and operate databases.Reference: 【Web開発の基本】初心者が知るべき重要な概念／QiitaThe main languages used in web development at Japanese IT companiesFrom here, we will introduce the languages that are often used in web development at Japanese companies.HTML, CSSJavaScriptPHPPythonJavaTypeScriptRubyHTML, CSSHTML and CSS are essential for web development. HTML is a language used to write web pages, and it can be used to create text, images, paragraphs, page structure, etc.CSS is a language used to set styles for pages written in HTML. It can be used to specify font size, font, color, etc. There are also development environments that can automatically generate HTML and CSS, so if you make good use of these, you can develop efficiently. When working on web development, you will need to understand the syntax of HTML and CSS, as you will sometimes need to look at the source code itself to make improvements or find problems.Reference: HTML/CSSとは？初心者向けの基礎知識と学習サイト5選／SAMURAI ENGINEER BlogJavaScriptJavaScript is a language used to create dynamic screen movements. For example, moving the mouse on the screen to make an animation appear is something that can only be achieved with JavaScript. Many websites and web apps now use animated features, and JavaScript is used for all of these. JavaScript is used frequently, so it is a language that web engineers must learn.Reference: JavaScriptとは？基本的な書き方や勉強方法～入門～／AKKODiSPHPPHP is a programming language developed for website creation, and it can be used to develop all kinds of website elements. As it is not the latest programming language, there is a good chance that it will be overtaken by other languages in the future.However, there are already many websites that have been built using PHP, and there are many opportunities to use it for adding functions and operational tasks. For this reason, it is one of the languages that web engineers should learn.Reference: PHPとは？基礎知識、できることを初心者にもわかりやすく解説します／カゴヤのサーバー研究室PythonPython is a language that is used not only for website construction, but also for AI field development.
