在福利多元化的發展下，需要跨不同的組織來回應複雜的社會問題並提供服務，為了整合這些服務需要跨界活動，而組織中的中階管理者通常會被賦予跨界者的角色，需要調整其管理方式以適應當前環境。本文因應管理模式的轉變，採用研究紀要（Research Notes）書寫，探討社會服務組織中階管理者在面對管理質變與崛起，應有的新思維與核心價值反思。本文引用英國Williams（2019）提到社會服務組織中階管理者，對外需要擔負起網絡管理「跨邊界者」（boundary spanner）的角色，對於組織內部，中階管理者需與各部門協調與合作，都是需要積極的參與，才能使水平、垂直的網絡體系，發揮最佳的效果。筆者亦透過反思，在面對管理主義與專業價值的變遷之下，「跨邊界者」在當中的思辯角色。

Under the development of welfare diversification, it is necessary to cross different organizations to respond to complex social issues and provide services. In order to integrate these services, it is necessary to handle boundary activities. Middle managers usually become boundary spanners and need to adjust their management methods to adapt to the current environment. Through the transformation of the management model, this article uses the research notes method to explore the response of social service organizations, the new thinking and core value reflections that the managers of social service organizations should have in the face of the qualitative change and rise of management. This article quotes Paul Williams（2019） from the United Kingdom as mentioning that social service organization managers need to take on the role of network management "Boundary spanner". From the internal perspective of the organization, the coordination and cooperation between managers and various departments is the role of network management outside the organization needs to be held or actively participated in the discussion. The author also through reflection, facing the shift of managerialism and professional values, the "boundary spanner" plays the role of speculation.
