The first step towards success in a software project is to ensure a professional setup. This includes a metrics-based formal estimation process to ensure a solid foundation for project planning. Accurate estimates require quantitative measurements, ideally tool based. In addition, software project managers must also monitor and update these estimates during the projects lifecycle to control progress and assess possible risks. Based on their many years of practical experience as software managers and consultants, Manfred Bundschuh and Carol Dekkers present a framework of value to anyone involved with software project management. They present all five ISO/IEC-acknowledged Functional Sizing Methods, with variants, experiences, counting rules and case studies, and they use numerous practical examples to show how to use functional size measurement to produce realistic estimates. Written in a highly practical style, including checklists, templates, and hands-on advice, and backed up with many pointers to both national and international metrics and standards organizations, this book is the ideal companion for the busy software project manager or quality assurance manager.
