設計時の見落とし Advent Calendar

システム開発する際に仕様書を作成するのですが、開発途中で気がついて仕様書を修正したり、ユーザーから指摘されたりするなど仕様の見落としがあります。
早い段階で気がつけばいいのですが、それなりに経験が必要です。後戻りの工数もバカになりません。
設計時に見落としていたことを書いてもらい、今後の開発に活かしていこうとう趣旨となります。

どんなことを書くかというと下記は10年前に書いたスライドです、参考になればと思います。
https://www.slideshare.net/yaju88/ss-9001669

どこに書けば良いの？

Qiitaやブログ、gistなどでも構いません。
