企業考量成本因素與品質因素，將資訊系統委由其它專業之資訊廠商，以將更多的資源投注在核心能力的部分，這是現今許多企業採取的策略。對於專案開發的委外工作，企業與委外資訊廠商如何降低期望落差，達成更多的共識，讓專案的每一個階段，雙方依據一定的程序，緊密合作，達到如期、如質、如預算的目標，合約是一個很好的控管工具，如何擬定好一份好的合約，拉近企業與委外資訊廠商的認知，這是值得探討的議題。
軟體委外開發，多數企業對於產品上市或是企業內部流程需要性，縱使專案過程出現交付時程延遲，或是部分品質上的期望落差，多半選擇妥協，或是協商其他的補償，對於企業來說，其實都是額外成本的投入。企業與委外資訊廠商之間的專案合作爭議，不盡然是委外資訊廠商能力的不足，常常原因在於專案起始，雙方未能清楚溝通的合作程序，沒有合約，或者是合約內容對部分工作執行權責與標準沒有清楚揭露，大家各自解讀，沒有共識。
企業投注更多注意力於委外合約的擬定，相信有助於委外專案的成功率，或者當預期之外的專案發展，企業仍可以保有與維持基本權益。本研究參考數個較具規模的企業與軟體委外開發廠商之合約，提出軟體開發合約的基本架構，並蒐集台灣各地方法院的專案開發與軟體開發的民事訴訟案件，進行分類，經由實際案例的分析與探討，讓讀者對這些訴訟案例當作是最佳的經驗學習與分享，並提出合約擬定的重點補強。最後，依循軟體開發流程，歸納與提出企業應如何參與軟體委外開發工作，以充分發揮合約精神，將專案導向成功。
