Are object point estimation and cocomo 2 application composition model deprecated nowaday?



  • I have to estimate the effort required for a project and I have no historical data. In college I learned these methods, but I have the feeling that they have been replaced by new approaches such as story points (which need historical data such as velocity of iteration) in agile projects, for example.



  • These older estimation methods have not been 'deprecated'

    • Object Point and Function Point: https://en.wikipedia.org/wiki/Function_point is a better developed process than https://en.wikipedia.org/wiki/Object_point . For Function Point there are multiple professional organizations such as https://en.wikipedia.org/wiki/IFPUG , https://en.wikipedia.org/wiki/COSMIC_functional_size_measurement and ISO/IEC industry standards developed by them. Here is a recent review: https://www.ifpug.org/40-years-of-function-points-past-present-future/ . However, to count Object Points or Function Points, your client should have signed off on requirements and you need to have your high-level design done (to be able to count objects/functions).
    • COCOMO and COCOMO II: When I search for articles/blogs published within the last couple of years on this topic, I see many. However, this model is based on lines of source code. You will have to make a judgement call whether lines of code is at all a relevant metric for your project.
