Cost Estimation
Software Cost Estimation is the process that estimates the effort to develop software. There are several estimation techniques like Algorithmic Cost Modelling, Expert Judgement, and Estimation by Analogy, Parkinson's Law, and Pricing to Win. At here, we use Algorithmic cost modelling such as function points and basic COCOMO model to calculate the effort and development time to develop our software system. We have chosen Algorithmic Cost Modelling because it’s the most systematic, and COCOMO model give the reader an overview of cost estimation.
