Later, when analyzing the reasons why progress on the monitors slipped out of control, the main problem was in the initial evaluation--the technological level demanded on the product was too far beyond the original foundation. There were too many variables that could not be controlled, yet no additional time allowance was made.
事後分析開發進度失控的原因，主要是一開始就評估錯誤﹘﹘這項產品在技術層次上跳離原有基礎太多，本來就有許多無法掌握的變數，但時間給得太少。
