供應鏈的運作過程包含一系列的價值創造活動，這些活動乃是由許多不同的組織所負責執行，且每個活動之間存在相互影響的關係。在這一牽涉跨組織合作的價值網絡中，所遭遇的困難主要是來自跨組織互動過程中所隱藏的不確定問題，而這些問題的產生主要導因於供應鏈夥伴間的活動缺乏調和。針對供應鏈分散管控結構所衍生出的問題，近年來以資訊科技為基礎的跨組織系統 (inter-organizational system, IOS)提供了有效的解決方案。此IOS的形成，主要是認為透過IOS的應用，供應鏈組織可藉由跨組織資訊分享的力量來改善夥伴間的協調以及資源整合。而此意謂IOS的效益產生端賴系統內建的資訊分享機制能相容於供應鏈結構特徵，並能有效協助組織來因應所面臨的不確定問題。是以，建立一個相容於環境的資訊分享機制是配置IOS解決方案過程的重要關鍵，且對於供應鏈不確定的診斷在資訊分享機制規劃過程有其重要性存在。 對於供應鏈不確定問題的診斷是一極為複雜且具挑戰的任務，其須要透過一結構化的框架來協助分析夥伴間錯綜複雜的互動行為過程所隱藏的不確定因素。因此，本研究乃採用結構化的方法來製作一符合統計效度的不確定因素衡量量表，並以此量表為工具透過個案研究的方法來探索收斂組裝型供應鏈，這一特定型態供應鏈所面臨的不確定問題。在了解供應鏈所面臨的不確定問題之後，本研究試圖針對此供應鏈型態提出一資訊分享機制規劃的參考架構，藉此架構引領供應鏈運作環境中的資訊科技規劃，並依此提升供應鏈整合。 在針對個案探討之後，本研究發現缺乏妥善規劃資訊分享機制是導致個案公司目前仍難以有效因應所面臨的不確定問題之主要原因。所施行的資訊分享實務與供應鏈環境間的不相容使得其目前仍難以有效因應需求的變異以及物料供給的管控。此外，本研究發現資訊分享模式會受到所面臨的不確定問題之屬性以及嚴重性程度的影響。在收斂組裝型供應鏈的案例中，受到供應鏈結構特徵的影響，資訊分享應著重於物料供給方面的議題。因為在該型態供應鏈運作環境中，供應端的夥伴結合相對於需求端而言較為複雜，且與領導廠商間的關係又非似需求端夥伴間來的密切。是以，在收斂組裝型供應鏈中，有必要投注較多的心力於建制與供應夥伴間的資訊分享。 / Supply chain management is a complicated task because of uncertainties involved. The uncertainty that occurs in the processes of inter-organizational coordination is due to a lack of harmony in supply chain participant activities. Recent developments in Inter-organizational Systems (IOS) have contributed to the provision of IT-based solutions for harmonizing supply chain participant activities. Applying IOS to the supply chain often attempts to improve the efficiency of coordination and resource integration among participants via inter-organizational information sharing. This intention implies that the effectiveness of IOS depends on whether information sharing mechanism built into the system can fit for supply chain characteristics and can help the supply chain cope with uncertainties that disrupt the integration of the supply chain. Hence, establishing an environment-suited information sharing mechanism is critical in deploying IOS solutions, and diagnosing supply chain uncertainties is important in planning information sharing mechanism. Diagnosing supply chain uncertainties is a complex and challenging task, it needs a structural framework to support in analyzing the intricacy of interactions among supply chain members, resulting in the construction of an instrument to assist in the understanding of uncertainty-related behaviors of supply chain participants. Therefore, this study takes a structural approach to produce a validated uncertainty scale, and applies a case study approach with this instrument to investigate the uncertainty problems in a specific supply chain type, convergent assembly supply chain. After understanding the uncertainty problems, this study proposed a reference model to assist this supply chain type in planning an information sharing mechanism, leading to a well-suited IT framework to improve supply chain integration. Falling short of a sounding information sharing mechanism is central to the problems in convergent assembly supply chain based upon the findings of case studies. The incompatibility between supply chain environment and existing information sharing practices has led to the problems in demand variation and material supply. Based on the characteristics of supply chain environment, planning inter-organizational coordination and information sharing simultaneously can effectively resolve the supply chain problems. Moreover, the research results suggested that the pattern of information sharing is influenced by the scale and severity of the uncertainty embedded in supply chain. In the case of convergent assembly supply chain, information sharing is focused on issues related to material supply owing to the structural characteristics of supply chain. The combination of participants in supply side is more complex and is not familiar with the leading company as demand side’s participants. Therefore, it needs to pay more attention for establishing information sharing among supply side’s participants.
