Comments on: It cost over $1.4 million to develop CakePHP http://developingwithstyle.com/2008/06/05/it-cost-over-14-million-to-develop-cakephp/ A Weblog written, styled and hacked by Joel Moss Fri, 21 Nov 2008 09:28:46 +0000 http://wordpress.org/?v=2.6 By: beberlei http://developingwithstyle.com/2008/06/05/it-cost-over-14-million-to-develop-cakephp/#comment-116 beberlei Tue, 01 Jul 2008 22:18:26 +0000 http://developingwithstyle.com/?p=179#comment-116 The numbers of the COCOMO model are estimated using Linear Regression and a training data set of 60 projects back in the late 70s, were IT projects were mostly done for governments organizations and huge companies and took several years and more than 10 programmers full time. The cocomo model used by Ohlo is also very very low level. You can extend the one with 16 different information variables on how the project "behaved" in terms of complexity, team integration, tools, schedule whatsoever, which significantly optimizes the results. The estimated coefficients of this model are not at all relating to the current software development cycles. They do not include Object Oriented programming and Rapid Development cycles. They are also based on projects written entirely in Assembler, Fortran or C, languages which are known to take lots of lines of code to do the same as PHP or Java would do. You can effectivly divide the number by 2 or 3 to get a better result.

A fun example of mythical man month but interesting to see what some might value things Sam D Actually if you want to make your self feel under appreciated take http://www.dwheeler.com/sloccount/ and run it over some of your code.

For the most part it's just guess work based on the little information that they have from the repository. The cost and time is based off the Basic COCOMO that takes into account for design, specification drafting, reviewing, management overhead, and the actual coding. So basically it is an estimate for a large corporation to do the same project.
