Software Project Management




                    Notes          will be able to understand  whether the project is also on-budget. If it is not,  you can  take
                                   corrective action. EVM principles can be extended to Forecasting, TCPI, and Variance Analysis.
                                   EVM is an input to project performance reviews. Therefore, it is critical for you to understand
                                   EVM formulae so that you can use them as inputs to other cost control techniques.
                                   Earned  Value Management  (EVM) is  a well  known project  management  technique which
                                   measures the integration of technical performance, cost and schedule against planned performance
                                   within  a given project. The  result is a simple  set of  metrics  providing  early warnings  of
                                   performance issues, allowing for timely and appropriate adjustments. In addition, EVM improves
                                   the definition of project scope, and provides valuable metrics for communicating progress to
                                   stakeholders. The information generated helps to keep the  project team focused on making
                                   progress.

                                   Forecasting
















                                   EVM provides formulae to forecast the future performance of a project. The forecast is based on the
                                   current actual performance. As a project manager, having the ability to tell whether your project
                                   will be delivered on-time and on-budget is critical. Let’s take an example to understand this.
                                   Suppose you have completed 25% of your project. As per the schedule you are on track. However,
                                   after completing 50% of the project, you realize your project is delayed. By using forecasting
                                   formulae you can determine the degree of delay. This will also enable you to investigate the
                                   cause of delay and the corrective action, such as Crashing, required to get the project back on
                                   track. In addition, to the schedule delay you can use EVM Forecasting formulae to determine the
                                   actual cost of the project on completion and take measures to rectify any anomaly before it is too
                                   late.

                                   To-Complete Performance Index (TCPI)

                                   If the project is delayed or over-budget, you can use TCPI to determine the project performance
                                   required to complete the project as budgeted or estimated. TCPI also leverages the EVM formulae.

                                   Variance Analysis

                                   Variance analysis is the comparison of expected project performance to the actual cost performance.
                                   This analysis helps you understand the causes of variance, if any. Preventative and corrective
                                   actions are determined based on the variance analysis.

                                   Performance Review

                                   Performance reviews  in projects  are required to check  the health of a  project. This  usually
                                   involves Cost and Schedule as the main parameters to assess.
