功能模塊獨立性是由內(nèi)聚性和耦合性兩個定性指標(biāo)來度量的。內(nèi)聚性是度量一個功能模塊內(nèi)功能強(qiáng)度的一個相對指標(biāo)。耦合性則用來度量功能模塊之間的相互聯(lián)系的程度。

內(nèi)聚

內(nèi)聚是從功能角度來度量功能模塊內(nèi)的聯(lián)系，一個好的內(nèi)聚功能模塊應(yīng)當(dāng)恰好做一件事。它描述的是功能模塊內(nèi)的功能聯(lián)系。

內(nèi)聚有如下的種類，其內(nèi)聚度由弱到強(qiáng)排列：

☆偶然內(nèi)聚。一功能模塊中的代碼無法定義其不同功能的調(diào)用。但它使該功能模塊能執(zhí)行不同的功能，這種功能模塊稱為巧合強(qiáng)度功能模塊。

☆邏輯內(nèi)聚。這種功能模塊把幾種相關(guān)的功能組合在一起，每次被調(diào)用時，有傳送給功能模塊參數(shù)來確定該功能模塊應(yīng)完成那一種功能。

☆時間內(nèi)聚。這種功能模塊順序完成一類相關(guān)功能，比如初始化功能模塊，它順序為變量置初值。

☆過程內(nèi)聚。如果一個功能模塊內(nèi)的處理元素是相關(guān)的，而且必須以特定次序執(zhí)行則稱為過程內(nèi)聚。

☆通信內(nèi)聚。這種功能模塊除了具有過程內(nèi)聚的特點外，還有另外一種關(guān)系，則它的所有功能都通過使用公共數(shù)據(jù)而發(fā)生關(guān)系。

☆順序內(nèi)聚。如果一個功能模塊內(nèi)的處理元素和同一個功能密切相關(guān)，而且這些處理必須順序執(zhí)行，通常一個處理元素的輸出數(shù)據(jù)作為下一個處理元素的輸入數(shù)據(jù)，則稱為順序內(nèi)聚。

☆功能內(nèi)聚。如果一個功能模塊包括并僅包括未完成某一具體任務(wù)所必需的所有成分，或者說功能模塊中所有成分結(jié)合起來是為了完成一個具體的任務(wù)，此功能模塊稱為功能強(qiáng)度模塊。
