For accurate results, standards for the measurement of the functional size of software require that the functionality to be measured be fully known. However, when estimating in the early phases of software development where there is a lack of detail, approximate sizing techniques must be used. This paper investigates ‘equal size bands’ approximation and fuzzy-logic based approximation techniques using...
Three of the major constraints on projects are scope (size), cost (money) and time (schedule). While the Earned Value Management (EVM) and Earned Schedule (ES) techniques manage the cost and time constraints they do not explicitly tackle the scope constraint. While scope management is recognized as a key success factor in software projects, there is a lack of formal techniques in the literature to...
In the actual competitive software industry, software development organizations need a better and formal estimation approaches in order to increase the success rate of software projects. However, currently the estimation approach typically employed in industry is the expert judgment ('experience-based'). Using measures and estimations that continue to be based on researchers' intuition does not contribute...
In software engineering, the standards for functional size measurement require that the functionality to be measured be fully known for accurate measurement results. Therefore, in the early phases of software development, when there is a lack of detail, approximate sizing approaches must be used instead of the standards themselves. Approximate sizing techniques are typically based on the analysis...
In mature engineering disciplines, international consensus can be reached on measurement, as evidenced through established measurement standards. In software engineering, there are 5 functional size measurement standards. These standards work best when the functionality to be measured is fully known, although this usually doesn't happen in the early phases of software development. The techniques most...
