Xingui He · Jisuanji gongcheng yu sheji · 2005
Software development consists of many related software processes; the key of successfully analyzing the quality factors of aspecific software process is to eliminatethe effects from other processes. Traditional shewhart control charts can only distinguish commoncauses from assignable causes, but it can't be used to identify assignable causes from other processes. Total quality and partial qualityof software development processes were defined. The assignable causes were divided into process-inner assignable causes and process-outer assignable causes, and shewhart control charts and select cause control charts were used to identify variation sources that result insoftware process variation. A diagnosis table was summarized that helps to resolve every variation scenario of software process quality.
