Estimation of software products verified, maintained, and can be achieved Based on data collected by the International Software Benchmarking Standards Group (ISBSG), Practical Software Project Estimation explains how to accurately estimate the size, cost, and schedule of software projects. Verification Determining project objectives and requirements, validate, and refine the software functional size Generating indicative estimates using regression equations Predicting the effect and duration through comparison and analogy estimation frameworks Build Repositories ISBSG Perform benchmark using IFPUG Compare, Cosmic, and FiSMA sizing method Peter Hill is the chief executive officer and director of such ISBSG.
