Process 就像是「套路」。

沒有內功，只有套路，那只是花拳繡腿。

就像下面這一段：亢龍有悔。
「洪七公左腿微屈，右臂內彎，右掌劃了個圓圈，呼的一聲，向外推去，手掌掃到面前一棵松樹，喀喇一響，松樹應手斷折。 」

「郭靖拉開式子，挑了一棵特別細小的松樹，學著洪七公的姿勢，對準樹幹，呼的就是一掌。那松樹晃了幾晃，竟是不斷。洪七公罵道：『傻小子，你搖松樹幹什麼？捉松鼠麼？撿松果麼？』」

在業界往往軟體工程導入，通常都是看到人家只是「左腿微屈，右臂內彎，右掌劃了個圓圈，呼的一聲，向外推去，手掌掃到面前一棵松樹，喀喇一響，松樹應手斷折」。然後就超級心動，覺得這招亢龍有悔真是好物！肯定可以讓我們輕鬆破敵！
