Can you introduce some document to do it (especially for CFP), or I use COCOMO… to estimate effort from CFP? Thank you 12/11/2018 at 16:24 #11385 Arlan LesterhuisParticipant Dear Dinh, One way is to consult the ISBSG database, which contains data of hundreds of software projects, including their sizes in CFP and effort. However, if you have data of some software projects of your own organization you can make a ‘conversion model’ yourself: download. 13/11/2018 at 04:43 #11386 Dinh TuyenParticipant At this time not exists a formal way to estimate effort from CFP? I need cover all others factors (environment, risk…) in formal way, and I will change those parameters depend on my company. Author Posts You must be logged in to reply to this topic.
