Software Project Planning (Estimation)
Software project planning actually encompasses all estimation, risk analysis, scheduling, and SQA/SCM planning. However, in the context of set of resources, planning involves estimation - your attempt to determine how much money, how much effort, how many resources, and how much time it will take to build a specific software-based system or product. The following topic categories are presented:
