While single component has explicit functions in runtime after strictly qualified , problems come out with composed components , which developed by different developers in different time . those problems are so called " feature interaction " . and those feature interactions , which influence the normal system operations and decrease the system efficiency , are called " feature interaction problem " , and should be checked out and be resolved 大多數(shù)構(gòu)件經(jīng)過了嚴(yán)格的質(zhì)量認(rèn)證,單獨運行時功能十分明確,但當(dāng)來自于不同開發(fā)者、不同開發(fā)時間的構(gòu)件組裝在一起時,就會發(fā)生很多問題,這些問題被稱為“特征干擾” ,而其中那些影響系統(tǒng)正常運行或降低系統(tǒng)運行效率的特征干擾被稱為“特征干擾問題” ,這些問題是必須被檢測出來并予以解決的。
