WHY YOU MUST CHANGE TO COSMIC FOR SIZING AND ESTIMATION

Jayakumar, K.R.

Estimation based on functional size is found to be more accurate and enable performance measurement and benchmarking. None of the existing software size measurement techniques is practically relevant, mathematically correct and applicable across all domains, other than the COSMIC. Many functional size measurement specialists have found that IFPUG Function Point Analysis (FPA) is less effective when measuring software, even when it is applied in its traditional MIS domain for which it was designed. Results from industry demonstrate that the COSMIC measures can be used successfully for productivity monitoring and estimating, where other measures have been tried and were found to be lacking. Whether you are looking at functional sizing for the first time or using any other method, if you do not adopt COSMIC, you are missing to exploit the game changing innovation!
