This is so because of the inability of traditional modes of financial analysis, like discounted cash flow, to incorporate most of the strategic benefits of FMS in its analysis. FMS investments are strategic investments and their full impact on the firm is not estimable in terms of cash flows. What is required in investment evaluation procedure to truly justify investments in FMS is the combination of both strategic and financial methods. The paper aims at evolving a new investment evaluation procedure which will integrate strategic planning with financial method.</p></div>","PeriodicalId":100476,"journal":{"name":"Engineering Costs and Production Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0167-188X(91)90001-I","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76946654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
