最有利標的決標準則對營造業的競爭模式造成很大的衝擊。能創造 業主最大價值的差異化策略逐漸取代單純的價格競爭。營建業需要一套 系統化的備標方式，以評估各項考量因子，找出最合適的決策。
本研究以 Porter 的差異化策略為基礎，作為系統化分析投標策略的 方法。並以集合住宅最有利標的案例為基礎，提出了其最有利標的投標 策略模型。為在有限資源下來進行最有利標決策，本研究建構了最有利 標的決策支援系統，同時考量評選委員會特性、廠商長期績效、差異化 策略成本、得分及投標門檻。協助廠商評估其最有利標投標策略。並透 過個案的操作，測試決策支援系統。在案例操作的過程中，觀察到營建 業差異化的競爭策略應至少包括：對評選委員會的掌握、兼顧各類評選 項目、控制策略成本、重視經常性的經營績效等。分述如下。
由各類專家和業主代表所組成的評選委員會，負責代表招標機構決 定最有利的投標者。理論上，評審委員會，應該依據評審準則客觀的評 分。但是，由於專家來自於不同背景與領域，可能對相同的策略有相當 差異的評分。因此，備標階段對委員會的組成特性必須特別注意，針對 不同專長的委員提出足夠深入的差異化特性，且選擇較一般化的語彙以 有效的傳達。
招標機構通常會依據個案的特性與評審委員會的建議，訂定評選準 則。投標廠商可從評選準則來判斷客戶價值的重要程度，並滿足所規定 的最低門檻。一般而言，當投標廠商僅採用等級較低的策略時，便能獲 得其基本分數。也就是說，投標廠商必須兼顧各種評選準則，以獲得佔 得分比重較多的基本得分。如果偏重某項策略，過度提高等級而導致其 他策略連最低等級都無法達到，將不易獲得整體品質最高得分。
進行差異化策略所需花費的成本會決定投標廠商可採用的策略數目
，進而影響了得分高低。所以所有低成本的差異化策略就應該優先採用
，以幫助廠商達到基本的門檻，並獲得相對的高得分。
從各國最有利標的評審準則來看，除個案特殊的需求外，也包含許 多投標者長期績效的評估。例如，公司的業績、形象、ISO 認證等。這 些長期經營績效有助於傳達有利訊號，減少不同類型評審間的認知差距
。因此，具有永續經營理念與維持良好公司形象的企業，才能具有較大 的勝出機率。投標廠商應該善用擁有的長期經營績效，適度提高其對應 策略，以發揮得分的綜效。
