None of these technologies have produced the anticipated efficiencies, or productivity gains, measured in source lines per person month (lppm).","PeriodicalId":311790,"journal":{"name":"Journal of Parametrics","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124941362","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}

By identifying the risk of cost escalation during the planning and conceptual design of built facilities, facility owners and project managers can better focus their efforts to control total project cost in these times of decreasing capital investment budgets. The specific focus of this research was to develop a methodology for analyzing cost data from existing facilities to generate cost-probability curves and range estimates for facilities at the conceptual stage of design, that could be used in turn to identify critical variables to be managed for controlling project costs.","PeriodicalId":311790,"journal":{"name":"Journal of Parametrics","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133263914","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}

Several studies report the costs but ignore the benefits. Others focus on the benefits, but ignore the costs. For example, a widely circulated report by Coopers & Lybrand and TASC (1994) concludes that the DOD regulatory cost is significant, and the requirement for earned value management systems (EVMS) criteria is among the largest cost drivers. However, the benefits of the earned value information derived from criteria-compliant contractors were not considered. Clearly, a report that addresses only the costs or the benefits of earned value may be misleading. This study addresses both the costs and the benefits of earned value. The earned value concept and the related criteria are considered. Based on a comprehensive literature review, studies reporting the costs or the benefits of earned value are summarized and synthesized. The result is a report that...","PeriodicalId":311790,"journal":{"name":"Journal of Parametrics","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126320222","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}

We undertook the task of adding Common Object Modeling (COM) to our Hardware Acquisition (PRICE H), Hardware Life Cycle (PRICE HL), Module/Microcircuit (PRICE M), and ForeSight models. A COM aware software application acts as a server and/or client program that recognizes the PC industry-wide standard for inter-program communications. Adding this capability to two similar applications, PRICE H/HL/M and ForeSight, that were developed using vastly different technologies, needed two very different cost estimates.
