日本のソフトウェアは技術的品質が低く多額の損失を生んでいる
多くの日本製ソフトウェアはセキュリティ、保守性、拡張性、堅牢性といった技術的品質が欧米と比べて極めて低いため、機能追加やアップデート、リファクタリングなどの開発作業が非常に困難です。このような技術的品質の低いソフトウェアの開発・運用は、たとえ世界トップクラスのエンジニアであっても多くの困難を伴い、時間を要します。そのため、どの作業にも時間がかかり、開発費や保守費が莫大になったり、セキュリティが脆弱であったり、開発や運用そのものが困難になることさえあります。
技術的品質の低さの最大の要因は、技術的な品質の評価が全くできない人物が開発リーダーになる場合がほとんどだからです。彼ら/彼女らが品質を上げる作業を禁止し、実装のスピードだけで開発者を評価します。開発者が品質を高めるために、問題を指摘したり、調査をすると「仕事ができない」という評価をされ社内で見下されるようになるため、非開発者には理解できない技術的品質はほとんど無視されて開発が行われます。
技術的品質の低いソフトウェアは、品質が高いものと比べ、作業時間が数倍、数十倍、数万倍になります。毎年数千万から数億の損失を出していると推計される、プロジェクトが代表の経験で複数ありました。多くのエンジニアやPMと長年この問題について話してきて確信を持って言えることが、日本国内のソフトウェアのかなりの割合がこのように技術的品質が低く、多額の損失を生み出している可能性が極めて高いということです。

日本のソフトウェア開発のレベルは、業界最大手の企業を含めて欧米に比べて圧倒的に劣っています。多くの日本製ソフトウェアはセキュリティ、保守性、拡張性、堅牢性といった技術的品質が極めて低いため、機能追加やアップデート、リファクタリングなどの保守作業が非常に困難です。その結果、どの作業にも時間がかかり、開発費や保守費が莫大になったり、開発や運用そのものが困難になることさえあります。このような技術的品質の低いソフトウェアの開発・運用は、たとえ世界トップクラスのエンジニアであっても多くの困難を伴い、時間を要します。作業時間が数倍、数十倍、数万倍になることがよくあるので、大きな企業であれば毎年数千万から数億の損失を出している企業は多いと推測されます。
低品質なソフトウェアの開発においては、エンジニアの技術レベルに関わらず作業が進まなくなることが一般的です。しかし、日本の開発現場では品質を適切に評価できる人間がリーダーになることはほとんどなく、開発が予定より遅れると、どれだけソフトウェア自体に問題があっても、エンジニアの責任とされがちです。「仕事が遅い」「使えない」とレッテルを貼られたエンジニアたちは、技術のわからないリーダーから叱責され、見下されることが多く、その結果として精神的に追い詰められることが多々あります。納期が絶対であるという日本の商習慣が、この問題をさらに悪化させています。
実際、弊社代表の過去の同僚エンジニアの約7割が精神疾患を患った経験があり、鬱で退職していく人々も数多く見てきました。2000年前後には「3日連続の徹夜は当たり前」とされ、深夜にトイレに行った同僚が戻ってこず、確認しに行ったところ亡くなっていたという話も聞きました。このような過酷な労働環境を平然と語る40〜60代のIT業界経験者は非常に多く存在します。過去30年間、このような狂った状況が続いた結果、現在ではエンジニアが深刻に不足しています。

上記の問題について、日本のIT企業で長年働いているマネージャーやエンジニアのほとんどは認識していないか、もしくは自身のプライドを守るために現実から目を背けたり隠蔽している状況です。この劣悪なソフトウェア開発の慣習は、77万人の従業員を抱える外資系SIerの日本支部や、従業員3700人の日本の大手SIerなどでも同様であり、私の知る限りでは、一社の大手日本メーカーを除いて、20社以上の日本のソフトウェア開発現場に共通しています。
弊社代表は上記の問題を含めた日本のIT業界の様々な問題を長年分析して、解決策を実行した経験を生かし、これらの日本のソフトウェア開発の問題が一切ないソフトウェア開発サービスを弊社の開発チームは提供できます。

Mixing Waterfall and Agile Methodologies
To mitigate the weaknesses of both the waterfall and agile methodologies, we strategically integrate them, selecting key elements that minimize their shortcomings and enhance their strengths.
From the Waterfall Methodology:
-
Comprehensive Initial Planning: We emphasize creating an overall foundational design in advance, such as UI/UX and technical architecture selection, to minimize major structural errors often discovered during the sprint phase in agile development, which lacks comprehensive planning and design.
From the Agile Methodology:
-
Iterative Development Cycle: All initial plans are inherently incomplete and require continuous adjustments and changes. We create short-term plans in sprint planning based on the initial plan and the findings up to that point, enabling us to flexibly adapt development to ongoing changes.
-
Enhanced Customer Involvement: The product owner, who determines product direction, participates in all sprint planning sessions. This allows decisions for short-term development to be made considering the current state of the application, resulting in an app that better reflects the product owner's vision compared to the waterfall method.
-
Reduced Development Documentation: While development documentation is essential for knowledge sharing and maintenance, minimizing its volume is crucial to reduce costs associated with keeping the documentation consistent with the latest version of the software.
Comparison of Project Management Methodologies
Waterfall Methodology is a development approach that follows the sequential steps of 1. comprehensive planning and design, 2. implementation, 3. testing, 4. deployment, and 5. maintenance. It is a management methodology that was created in 1956 and has been used for decades. Its strength lies in its ability to create an overall project schedule and cost estimation by conducting detailed planning and design at the beginning of the project, which helps reduce rework and thus leads to cost savings. This approach is well-suited for projects with stable, well-understood requirements and environments where changes are undesirable or unlikely, such as regulatory or safety-critical projects.
However, Waterfall's lack of flexibility makes it difficult to adapt to changes that may arise in the later stages of the process. Additionally, maintaining detailed documentation can be costly, and inconsistencies between documentation and the actual software are common risks, especially if cost-cutting measures lead to outdated records. These inconsistencies can grow over time, creating challenges in further development, particularly if the original developers leave the company. Despite the rise of Agile methodologies, Waterfall remains a suitable choice for large-scale projects where predictable schedules, comprehensive documentation, and extensive testing are necessary, such as operating systems or major banking systems.
Agile Methodology is an iterative approach involving short cycles (sprints) of 1 to 4 weeks, where planning, implementation, and testing are repeated to gradually build the product. It was developed to address the rigidity of traditional methods like Waterfall, allowing teams to adapt quickly to changes. Agile's strengths include continuous customer involvement, flexibility, and rapid delivery, making it ideal for projects where requirements frequently change, such as web applications, browsers, and services. Agile allows teams to make adjustments throughout development, ensuring the product evolves according to customer needs and feedback. This responsiveness leads to higher customer satisfaction and products that better meet user expectations. Agile’s iterative approach also promotes early detection and resolution of issues, improving overall quality. According to the CHAOS Report 2015 by The Standish Group, Agile projects have a higher success rate of 39% compared to Waterfall projects, which have a success rate of only 11%.
However, Agile has some weaknesses compared to Waterfall. Without comprehensive initial planning, it is difficult to predict overall schedules and costs, and budgets often remain uncertain. The lack of a detailed upfront design can lead to missed fundamental architecture considerations, resulting in challenges when scaling or integrating the system later. Agile projects also face the risk of scope creep, where ongoing changes may cause uncontrolled growth in requirements.
Hybrid Project management
Phase 2:
Development / Sprints
The development phase is divided into Sprints—short, time-boxed iterations focused on delivering incremental product improvements through continuous feedback and iterative progress.
1. Sprint Planning
In sprint planning, the team refines and prioritizes user stories, estimating the effort and breaking them into manageable tasks. The resulting sprint backlog, built around user stories, guides the team throughout the sprint and aligns with the project roadmap. Regular input from the product owner ensures the plan focuses on the most valuable features.
2. Daily Scrum
Daily Scrums are short, focused meetings held every day, typically lasting 15 minutes. During these meetings, team members discuss their progress since the last meeting, outline their plans for the day, and identify any obstacles that could impact their work.
3. Coding
Coding involves translating user stories into functional software while adhering to established coding standards and best practices. Throughout the coding process, essential documentation is maintained, including code comments and API descriptions.
4. Testing
Unit testing and integration testing are performed alongside coding to ensure that each component functions correctly. These testings are crucial process that enhances the software’s reliability, maintainability, and overall quality.
5. Quality Assurance
QA involves thorough testing of completed features to ensure they meet standards. This includes functional, performance, and security testing, as well as usability, compatibility, and regression testing to verify that new changes do not introduce issues in existing features.
Phase 1:
Planning and setups
Establishes goals, design, and architecture, setting the foundation for development.
1. Plan
In the planning phase, we collaborate to understand your goals and initial requirements. Our iterative approach allows us to adapt through each sprint, ensuring dynamic resource allocation and risk management, aligning your project with your vision.
2. UI/UX Design
We ensure your app meets the highest usability and technical standards. Our UI/UX designers work closely with your product owner, refining wireframes and prototypes to create an intuitive and functional design.
3. Architecture Development
We create a scalable, secure architecture blueprint for your application. By defining the system structure and selecting appropriate technologies, we minimize risks and set the stage for efficient development.
1. Deployment
In the deployment phase, we release your app to the market, handling server configuration, database setup, and platform-specific requirements. We monitor the launch to address any issues quickly.
2. Maintenance and Support
Post-deployment, we provide ongoing support, including performance monitoring, bug fixing, and regular updates to keep your app competitive and aligned with user needs.
Phase 3:
Deployment and Maintenance
Ensures smooth launch and provides ongoing maintenance and support.

-
All developers have years of experience conducting research and learning in English.
-
We actively adopt new development best practices and tools, continually updating them to pursue the optimal combination.
-
Since there is a learning curve for each language, framework, and tool, we limit the technologies used in-house to the best options and manage to prevent excessive diversity. Developers acquire basic knowledge of each framework and tool early, and learn advanced knowledge as needed. Proficiency levels are checked regularly.
-
Understanding basic algorithm analysis and commonly used data structures is an essential skill for all developers.
-
All developers have a deep understanding of the architecture used, as well as the ability to implement loose coupling, modularization, and various types of testing.
-
Test code is always written for all business logic, ensuring smooth feature development, refactoring, and bug fixes, allowing engineers to work without stress.
Non-technical Guidelines
-
All employees are evaluated fairly and impartially based on their job performance, regardless of educational background, work experience, age, gender, or race.
-
In all planning and evaluations, decisions are not made based on authority but are instead based on critical thinking, emphasizing objectivity and evidence-backed logical opinions.
-
We encourage open communication, allowing everyone to freely express their opinions. Disagreements or debates with superiors are also welcomed, as long as they are not driven by self-centered reasons.
-
We do not tolerate any harassment and strive to eliminate bullying and power harassment. To promote open communication, it is essential to remove the threat of harassment. Even if an individual possesses important skills for the company, they will be punished if they engage in bullying.
