客服中心是企業提供客戶服務的關鍵部門，隨著商業模式不斷創新，各企業紛紛運用客服中心作為提升顧客體驗及拓展客群的手段。尤其近來雲端技術的興起，導入新技術勢必造成客服中心在服務流程上的驟變，如何安排客服中心業務流程、提供客服人員舒適的工作環境、強化顧客滿意度以及提高客服中心的營運效率，已成為一個亟需解決的問題。 精實原則致力於消除生產流程中的浪費並專注於加強業務流程中有價值的部分。在過去精實原則常被應用於製造業的生產工廠中，用以改善流程中的浪費，以達成無縫的拉式生產，然而近年來許多研究顯示此法應用於純服務環境亦同樣能有效的降低成本。 本研究起因於研究對象電力公司之客服中心面臨營運問題，包括過高的營運成本、人力配置不均以及人員流動率過高，另外還包含未妥善利用訊系統導致客服人員話務量增加與組織內部各單位資訊不同步造成資訊不準確等問題。為了解決這些問題，以客服中心之電話服務流程為主要研究範圍，採用精實方法之價值流圖(Value Stream Mapping, VSM)作為流程分析方法，剖析造成上述問題的原因，並基於精實原則(Principles of Lean)來思考，除了找出客服中心營運上的浪費之外，並針對個案公司所面臨的問題提出改善建議。 / Call center is an important unit in contemporary enterprise.
