專案是維持公司競爭力的必備要素，然而專案卻有著很高的失敗率。本研究將專案個案分類，並探討不同類別專案的關鍵成功因子為何？利用同專案類型內的比較與跨類型的交叉比較，分析並解釋不同專案的不同關鍵成功要素。
本研究收集了8個訪談案例，並且限縮至5個。根據研究的發現來解釋不同的類型為何有著不同的關鍵成功要素。會依照專案的重要性做分類為核心事業與支持性專案。從研究的分析發現專案成功的定義會影響專案成功關鍵要素，重視專案成功，也就是重視產出交付標的未來的價值，該類專案之關鍵成功要素偏向長期的指標。
除了發現定義專案的成功與成功關鍵因子的關係，也發現不同專案性質的成功關鍵因子。核心事業類的兩個專案同質性很高，都是為新創團隊設計並製造產品，研究發現兩個專案有著獨特的公同成功關鍵要素:接案時的審核，但是因為兩者對於專案的成功定義不同，而有不同的策略。
總結，發現依照重要性區分的兩類專案，有著相同的關鍵成功因子那就是利害關係人管理。核心事業：經常性的專案會有許多累積的歷史資料，並且會發展出自己一套的關鍵成功因子。而支持性專案比較無過去的資料可參照，必須依賴不斷的與利害關係人溝通協調來達成專案目標。

Project is an essential element to maintain the company's competitiveness, however the project has a very high rate of failure. This study classifies project cases and explores key successful factors for different types of project. Then study analyze and explain the different key successful factors for different projects using comparison within same type and cross-type comparison.

The study collected eight interview cases and limited to five. According to the findings of the study to explain why different types have different key successful factors. Project will be classified according to the importance of the project as a core business and supportive projects. Study found that the definition of project success will affect the combination of project key successful factors. The project defines its success as “project success”, which means project pay attention to the future value of deliverables, and this kind of project’s key successful factors tend to be long-term indicators.

In addition to discover the relationship between the definition of project success and the key successful factors, key successful factors for different project type were also found. The two projects of the core business type are highly homogeneous and they both service for star-up companies. The study finds that the two core business projects have unique and common key successful factor - review the case before accept, but their review have different aspects of observation which depend on the definition of project success.

In sum, the study found that the two types of project which classify by importance of projects. Both of them have the same key successful factor which is the stakeholder management. Core business: Regular projects have a lot of accumulated historical data that develop their own key successful factors. The supportive projects have less historical data to refer. This kind of project must rely on continuously communicating to and coordinating with stakeholders to achieve the project objectives.
