Effect of Variations in Measurement Process for Software Development Efforts

Researchers have proposed that the reliability of software prediction models can be assessed by the following most widely used evaluation criterion, i.e., Difference Measure and Ratio Measure. Ratio measure is more suitable for the assessment of the accuracy in software cost estimation. Results in this research demonstrated that applying proposed method to the software effort estimation is by far the most feasible approach for addressing the problem of apprehension and ambiguity existing in software effort drivers. Small adjustments to the COCOMO cost drivers bring significant improvements to the quality criteria applied to the proposed approach.
