In all projects where we could identify the presence of one or more test-related agile practices, problems with testing were less
frequently reported than in the other projects.
Contemporary scientific software-development projects embrace the agile spirit in their focus on flexibility and communication, but otherwise are selective in using specific agile practices according to the book.
Some of the more technology-driven practices simply might not be known to scientists who aren’t professional software developers.
Nevertheless, the literature review indicated that agile techniques generally had positive effects in the projects investigated.
The agile approach can be valuable to scientific software
development, especially for smaller-sized teams and projects.
テスト関連のアジャイルプラクティスを使ったプロジェクトでは，テストの問題はあまり報告されなかった．
柔軟性とコミュニケーションに焦点を当ててアジャイルの精神を取り入れている．
