從民國四十幾年開始，水量計製造業如雨後春筍般蓬勃發展，但到民國六十幾年到七十幾年間，在政府法規的訂定下，提高了此產業的進入障礙，同時也提高對於品質的要求，許多經營體質較差的公司相繼倒閉。直到民國七十幾年以後，市場由三家較有規模的企業相互競爭，而民國八十年才成立的EMS公司便是其中之一。而在強敵環伺的競爭環境中，EMS如何善用行銷策略脫穎而出，便成為了本研究探討的主要議題。
EMS公司過去十餘年來的投資報酬率，幾乎每年維持在正數以上，且其中ROI有愈來愈高之趨勢，以水量計製造業此一飽和市場而言實屬不易。探究EMS公司之成功原因，正是因為區隔出利基市場並善用行銷策略來行銷。目前水量計製造產業的市場型態，正是屬於一寡佔市場，在此市場中，廠商的策略作為相當重要，因此，EMS的成功因素值得我們去深入探討。
在對EMS公司進行研究後發現，EMS公司自有一套行銷策略的發展模式。EMS公司主要銷售為自來水公司供水計量之電子式水量計，以和其他競爭廠商的機械式水量計和用戶表做區隔。在定位上，EMS公司自詡為「客戶用水系統之全方位服務」提供者，並全力提供相關的產品和服務，包括產品方面：各式水量計、電子讀表介面與系統、水資源專家管理系統；通路方面，針對水公司各管理處皆設置固定的行銷業務；另外在公共關係上，EMS公司特別重視公共關係之訴求，多次贊助或協助文教或公益活動之舉辦，亦經常響應政府政策，朝節約能源的方向努力，讓民眾和機關都留下了正面而深刻的印象。十餘年下來，EMS公司都有不錯的獲利，且從對顧客問卷調查結果統計發現有80%以上的購買者對EMS公司的產品感到滿意，可說是相當成功。
本研究希望能藉由研究EMS公司此成功個案之行銷策略實務經驗，從市場區隔、選擇目標市場、市場定位，到最後發展行銷組合策略的每一個歷程，做一詳實的探討與回顧，將EMS公司的寶貴實務經驗分享給業界及學界作參考，以期能對台灣水量計製造產業有所幫助。
