Mechanical designer deliverables check list

** 3C機構設計爸版權所有 ©️ **

在每個企業，想必都有所謂的SOP (Standard Operation Procedure)，整個部門的行政作業流程在SOP中都會被詳細的被定義，企業中、甚至部門內的SOP並不是只有一種，針對不的同功能、特定的作業，都會有不同相對應的SOP，並以SOP的編號登錄。然而機構設計部門所必須執行的每個細節，如何讓每個專案不會因為負責專案的工程師不同而造成事項被遺漏的情況，或是每個機構設計工程師在各個專案中的做法有差異的情況，端靠overall的SOP是不夠的，同時必須倚賴一份 check list 來做更詳細規範，清楚條列出在該專案中的每階段的每個事項，這種性質的 check list，3C機構設計爸把它定義為Mechanical designer deliverables check list。

Mechanical designer deliverables check list 必須包括哪些範圍呢？3C機構設計爸認為歸納以下項目會比較有效率的讓機構設計人員、甚至新進員工一目了然的看懂在一個專案的過程裡面，到底要執行的工作任務有哪些。

為了讓執行機構設計人員可以在專案之前就可以很清楚的了解進行專案的時候該做什麼事情，所以Check list中橫向的項目展開就以專案的階段來當作工作項目的區隔，企業中的專案階段有POC、EVT、DVT、PVT、MP(1)、MP(2)、MP。當然，也可以修改成為以客戶所使用的專案階段名稱，甚至在專案的額外需求下增加或減少專案階段，例如說 Pre-EVT、EVT(1)、EVT(2).....等等。

對於專案中所必須執行的細部事項，3C機構設計爸認為 senior Mechanical designer會比較清楚、所以這個 check list的template比較建議是由主管或資深的專案經理來製稿。以下是一個範例讓各位朋友參考

最後、也是最這份 Check list的最後重點，那就是在矩陣表格中做選項的定義，把Check list的項目訂出來之後，同時又有一個欄位讓機構設計工程師打勾，這樣可以確定該項目已經被執行了，甚至可以做出一個圖表，這樣就可以控制每一個項目的完成狀態，而且可以秀出完成率的 visibility。
