Joseph (Joe) Yoder (agilist, computer scientist, speaker, and pattern author) is the founder and principal of The Refactory, a company focused on software architecture, design, implementation, consulting, and mentoring on all facets of software development. Joe is also the president of The Hillside Group, a non-profit dedicated to improving the quality of life of everyone who uses, builds, and encounters software systems. Joe has presented many tutorials and talks, arranged workshops, given keynotes, and helped organize leading international agile and technical conferences. He is best known as an author of the Big Ball of Mud pattern, which illuminates many fallacies in software architecture. Joe teaches and mentors developers on Agile and lean practices, architecture, building flexible systems, clean design, patterns, refactoring, and testing. Recently Joe has been working with organizations and thought leaders on the best practices for including quality aspects throughout the complete software life-cycle. Joe thinks software is still too hard to change and wants to do something about this. He believes using good practices (patterns), putting the ability to change software into the hands of the people with the knowledge to change it, and bringing the business side closer to the development process helps solve this problem.

ビジネスと社会のためのソフトウェアエンジニアリングの研究、実践、社会実装に従事。その一環としてアジャイル開発のプロセスやプラクティスの分析を進め、2014年からJoseph YoderやRebecca Wirfs-Brockらのアジャイル品質保証パターンのプロジェクト "Shifting from Quality Assurance to Agile Quality (QA2AQ)"に参画。2019年からはアジャイル開発と従来のソフトウェア工学の間の分断、さらにはビジネスとITの間の分断が起きているという問題意識のもと、DX時代のオープンイノベーションに役立つデザイン思考やビジネス・価値デザインからアジャイル開発、さらには堅実なソフトウェア製品・サービスの開発・保守の方法論までを系統立てた枠組みとしてSE4BS（Software Engineering for Business and Society）の構築を有志で開始。
