三角不是藉口
專案三角提醒我們，限制客觀存在。它不應被用來推卸責任，而應迫使團隊說清楚：這次優先守住什麼。
變更一定有代價
範圍增加但預算與時程不變，代價往往被藏到品質、風險或團隊負荷裡。這些代價需要被看見。
用目標決定取捨
先理解產品與公司目標，再決定哪個限制可以調整。沒有共同目標，三角就只會變成部門之間的拉扯。
The Triangle Is Not an Excuse
The project triangle makes constraints visible. It should force the team to say what must be protected, not excuse poor decisions.
Change Has a Cost
When scope grows without budget or schedule changes, the cost moves into quality, risk, or team load. That cost must be visible.
Let Goals Drive Trade-offs
Product and company goals should determine which constraint can move. Without shared goals, the triangle becomes departmental conflict.
