在軟件工程化的實(shí)踐中，軟件研制過(guò)程反映出4類(lèi)共性的問(wèn)題：
?。?）項(xiàng)目軟件研發(fā)時(shí)間緊，人員少，人員投入度不足，人員職責(zé)不明晰，造成部分執(zhí)行要求被人為簡(jiǎn)化，甚至隨意取消；
（2）項(xiàng)目軟件的計(jì)劃性不強(qiáng)，經(jīng)常出現(xiàn)需求、人員、資源的變動(dòng)，造成了進(jìn)度拖延，計(jì)劃無(wú)法得到保證；
?。?）項(xiàng)目軟件研發(fā)過(guò)程中會(huì)議和文檔較多，但利益相關(guān)方的界定不明晰，造成不必要的“*會(huì)海”現(xiàn)象，降低管理效率，影響軟件設(shè)計(jì)工作；
?。?）管理人員和技術(shù)人員的工作過(guò)程缺乏足夠的監(jiān)管和測(cè)量分析，造成了項(xiàng)目管理進(jìn)程缺乏統(tǒng)一性和技術(shù)可重復(fù)性。
為了解決通過(guò)上述問(wèn)題，我們?cè)趯?shí)踐過(guò)程中逐漸摸索和總結(jié)出一些適合中小型嵌入式軟件研制方法。下面將從軟件項(xiàng)目管理體系和軟件項(xiàng)目研制過(guò)程兩方面進(jìn)行闡述。
