3. other app

better admin

2. Rails Engine1. app internal

app internalpros better testing better deploy

cons including difference application including effective code

Rails Enginepros splitting application code better deploy

cons difficulty testing can’t use production code directly

Other apppros definitely splitting app

cons separated develop cycle duplicated code

No silver bullet

できるだけ長い間,ユーザに価値を提供し,利潤を生み続けるWebサービスを運営するためには,継続的な改善を行うことが必要です。Webサービスを改善するには,技術的な取り組みはもちろん,開発投資とそのリターンという経営的な観点,チームビルディングなどの開発プロセス,ビジネスメトリクスへの注視など,考慮すべきことがたくさんあります。

スクラムは、「複雑で変化の激しい問題」に対応することを第一目標としたアジャイル開発手法です。数あるアジャイル開発手法の中でも、いま圧倒的に採用されています。 　本特集では、現在のソフトウェア開発におけるスクラムの意義から、実際の現場における取り組みまで、スクラムを徹底解説します。
