Quantifying requirements elaboration to improve early software cost estimation
نویسندگان
چکیده
This paper describes an empirical study undertaken to investigate the quantitative aspects of the phenomenon of requirements elaboration which deals with transformation of highlevel goals into low-level requirements. Prior knowledge of the magnitude of requirements elaboration is instrumental in developing early estimates of a project’s cost and schedule. This study examines the data on two different types of goals and requirements – capability and level of service (LOS) – of 20 real-client, graduate-student, team projects done at USC. Metrics for data collection and analyses are described along with the utility of results they produce. Besides revealing a marked difference between the elaboration of capability goals and the elaboration of LOS goals, these results provide some initial relationships between the nature of projects and their ratios of elaboration of capability goals into capability or functional requirements. 2009 Elsevier Inc.

Early Phase Software Effort and Schedule Estimation Models
Context: Software cost estimates have the highest utility at early elaboration phase. The dilemma, however, is that most input parameters needed for estimation are not available at this stage. Objective: This study introduces a set of effort and schedule estimation models for software development projects in the early elaboration phase. It evaluates the direct impact of functional requirements ...

متن کاملA New Optimized Hybrid Model Based On COCOMO to Increase the Accuracy of Software Cost Estimation
The literature review shows software development projects often neither meet time deadlines, nor run within the allocated budgets. One common reason can be the inaccurate cost estimation process, although several approaches have been proposed in this field. Recent research studies suggest that in order to increase the accuracy of this process, estimation models have to be revised. The Construct...
