Good Software Estimation Requires Historical Data

This article identifies the major features of software cost estimation tools and how they are being used together technically with project management tools. This article describes a number of experiences of early estimation of software reliability for large real-time telecommunications systems. Estimating Web Development Costs: There Are Differences The challenges in estimating cost and duration in Web development projects prompted one consulting firm to create a new size metric and a new cost estimation model. The estimating model in this article provides accurate early estimates by utilizing function points to identify project complexity modified by a value adjustment factor of 14 general system characteristics. The project in this article demonstrates a new way to develop government software using Internet-based tools to leverage costs among organizations. The size and complexity of algorithms in general and integration formulas in particular can be measured using function points without the need for additional patches or counting rules. Managers looking to initiate a software estimation process in their organization will get practical advice from this author's real-life experiences with estimation training methods. 3 26 27 31 D e p a r D e p a r t m e n t s t m e n t s BackTalk CrossTalk Article Submissions: We welcome articles of interest to the defense software community.Articles must be approved by the CROSSTALK editorial board prior to publication.
