你是老闆 / 決策者嗎？
對於實際負責現場的員工
有時候很怕遇到一種狀況
老闆：「我昨天聽見⋯⋯我覺
得我們公司應該要導入⋯⋯」

自動化能夠帶來許多好處
消除重複的工作
提升軟體的交付速度（節省時間？）
降低成本、消除浪費
降低人為錯誤
消除對個體或團隊的依賴

應用程式所需的 environment？
Deploy
從單一環節逐步開始
如何取得 Artifacts？
是否有其他初始化的動作？
如何因應「部署失敗」？
如何連上主機？ 需要額外的組態管理？
如何因應「重新部署」？
該選用哪種技術 / 工具？
技術及工具的決策？

技術轉移及技能喪失
In their efforts to compensate for the unreliability of human performance, the designers of automated control systems have unwittingly created opportunities for new error types that can be even more serious than those they were seeking to avoid.
—James Reason
更多的文件、培訓、訓練

自動化能夠帶來許多好處
但自動化的坑，比你想像的多
Oooops
自動化需要的資源（人力、工時），
也比你想像的多
自動化需要的評估關鍵，
也同樣比你想像的多
