摘要:In this paper we are introducing new method of software cost estimation for Agile based software projects (Web based agile projects) and also like to introduce how this method is improving performance and efficiency of Agile based Software cost estimation. Rapid application development model CORADMO provided cost estimation in the form of rapid person productivity count by using person-month (Effort) and month (Schedule), but CORADMO followed waterfall model, so in agile case we do not require waterfall model fully and in agile software development all the stage of development having rapidly change with customer requirements, and COCOMO-II have no longer support for this, we needed a new method to improve rapid cost estimation performances, and also relate with agile methodology and provide more matching relation with agile methods: DSDM, ASD, AUP and SCRUM.
