621-1101R 功能模塊化的根據是，如果一個問題有多個問題組合而成，那麼這個組合問題的復雜程度將大於分別考慮這個問題時的復雜程度之和。
621-1101R 這個結論使得人們樂於利用功能模塊化方法將復雜的問題分解成許多容易解決的局部問題。
621-1101R 功能模塊化方法並不等於·限制地分割軟件，因為隨著功能模塊的增多，雖然開發單個功能模塊的工作量減少了，但是設計功能模塊間接口所需的工作量也將增加，而且會出現意想不到的軟件缺陷。
621-1101R 因此，只有選擇合適的功能模塊數目才會使整個係統的開發成本·小。
621-1101R The basis of functional modularization is that if a problem is composed of multiple problems, the complexity of the combined problem will be greater than the sum of the complexity of the problems when they are considered separately.
621-1101R This conclusion makes people willing to use functional modularization methods to decompose complex problems into many easy-to-solve local problems.
621-1101R The functional modularization method does not mean unlimited division of software, because as the number of functional modules increases, although the workload of developing a single functional module is reduced, the workload required to design the interface between functional modules will also increase, and there will be Unexpected software bugs.
621-1101R Therefore, only by selecting the appropriate number of functional modules can the development cost of the entire system be minimized.
