The Remote Manifesto (ja)
The original is https://about.gitlab.com/2015/04/08/the-remote-manifesto/
We all have been greatly helped by Scrum and the Agile manifesto.
It freed us from waterfall planning and excessive process. But working
remotely and continuous delivery need something more.
私達は皆Scrumとアジャイルマニフェストに救われてきました。
それはウォーターフォールの計画ややり過ぎたのプロセスから私達を開放してくれました。
しかし、リモートでの働き方や継続的デリバリにはまだ何か必要なのです。
