Software development time and cost estimation

Estimate effectively The times and costs involved in a software development activity, whether it's a complex project or a simple maintenance task, are practices that project managers and, more generally, all those involved in software development constantly grapple with.
The estimate based on personal experience, still widely used today, often does not lead to good results and lacks the objectivity and repeatability necessary for a good estimation method.
This therefore creates the need to have more objective and formal techniques, comparable in heterogeneous environments, based on international standards and on more scientific criteria.
The course, after revisiting the most common problems in creating estimates, illustrates the reference metrics currently available for software measurement and the ways in which they are normally used, and examines some Techniques and best practices widely disseminated and frames them within a process that guides their use.
I Function Point IFPUG, The cornerstones of the course are treated with ample and exhaustive references to counting rules and widely used estimation techniques (E&QFP, FFPA), while for the thorny issue of converting size into effort, the most important indications provided by National and international guidelines, and the best practices currently adopted by the most advanced business realities.
The topic of the contractual use of Function Points and, more generally, software metrics is addressed as a corollary to the main arguments.
