資訊科技日新月異，再加上市場需求的瞬息萬變，使得競爭環境越趨劇烈，而企業得以永續經營的核心關鍵，就在於管理者是否能有效辨別其核心競爭能耐以及其在產品生命週期的發展情況，以提高資源分配的效率，能更快速反應市場的變化，並獲取競爭優勢。
以往企業多是以單一面向切入分析自身資源與能耐效益，本研究則是整合資源基礎理論、動態能耐、平衡計分卡、模糊集理論以及資料包絡分析之統合觀點來進行探討。於本研究中，在不同產品生命週期下，採用平衡計分卡為組織能耐因子的績效衡量構面，且企業組織能耐的狀態較為模糊，為一個模糊的決策問題。因此，本研究採用結合專家訪談結果以及模糊集理論之概念與計算方法，得出各週期下的相對重要性，並且採用資料包絡分析(DEA)，推演出績效因子之相對應效用。
而企業資源能耐在平衡計分卡(BSC)四大觀點下，根據不同的產品生命週期而有所變化，同時，探討在不同週期下企業應較注重的BSC觀點，期望投入較多資源於其中，以作為企業制定競爭策略的考量基石，取得領先對手的優勢，而獲得核心競爭優勢。

With the ever-changing information technology, operational related information is delivered in the ways of transparent and high-speed mode. Besides that, dynamic and highly uncertainty market demands cause more intensive competition between organizations. Therefore, the key factor to promote sustainable enterprises is that whether managers can leverage the core competency during the product life cycle. The core competency can be efficiently identified to improve the effectiveness and efficiency of resource allocation to response more quick changes in competitive environment, thereby enhancing core competencies to achieve competitive advantage. Under different product’s life cycle, this study adopts balanced scorecard (BSC) to measure the competency and performance of a firm. In addition, when the state of organizational competency is ambiguous, manager can’t clearly identify the core competencies of their organization. Therefore, this study integrates the results of expert interview and the concept of fuzzy set theory to build an approach to identify organizational capabilities for developing the competencies. Moreover, data envelopment analysis (DEA) is applied to acquire the best combination of resources and capabilities. The appropriate strategy can allocate available resources and capabilities during different product life cycle, which will help the top management to make better decisions.
