Software Size Estimation Techniques You don't have to do a full functional size count to estimate the functional size of a piece of software. There are a large number of software size estimation techniques available ranging from levels 4 to 6 . Three practical and well documented techniques are: Early estimation of functional size using the ISBSG function point component relationships (ISBSG) KISS Quick software size estimaton technique (FiSMA) Early and Quick software sizing technique (DPO) These are derived size estimation methods that use some sort of algorithms. These techniques are described in detail in chapter 5 of the book: Practical Project Estimation 2nd Edition.
