Size and Effort Estimation Techniques for Software Development
Chander Diwaker, Astha Dhiman · 2013
Abstract: Software development Cost estimation is process of predicting the most realistic use of cost required for developing software based on some parameters. The estimation of various project parameters that include project size, effort required to develop the software, project duration and cost. It has always the biggest challenges in computer science for last decades because cost and time estimate at the early stage are difficult to obtain and they are often least accurate. Nowadays software project managers should be aware about increasing of project failures. The main reason for project failure is imprecision in the estimation. Project managers stress on importance of improving estimation accuracy and methods to support better estimates. The researchers have examined several existing methods for software development cost estimation. Suitability of estimation methods depends on factors like software application domain, product complexity, availability of historical data, team expertise etc.
