          Earned Value (EV) Management                                                          Notes

          In earned value management the development of a project is estimated by comparing what
          already has  been done with the estimates that  were made  at the beginning  of  a project. By
          extrapolating these measurements, a project manager can judge how much resources will be
          used at the end of a project. Some ordinary acronyms that are used use in the EV management:
          BCWS          Budgeted Cost for Work Scheduled

          BCWP          Budgeted Cost for Work Performed
          ACWP          Actual Cost of Work Performed
          BAC           Budget at Completion
          EAC           Estimate at Completion

          Budgeted Cost for Work Performed (BCWP) is also identified as the earned value. This value
          shows what a project actually has earned at a certain point in time. The cost of an amount of work
          can be expressed in diverse ways.


                 Example: In dollars or in hours.
          Also one has to choose when something has been earned. It can be chosen to only set something
          to be earned when the full task is done. Or say that the part of the task that by now had been done
          has been earned. In the last case the problem is that estimating how far a task has progressed is
          complex.

          Advantages

          In a project a manager can judge if the projects are on schedule/budget. If that’s not the case an
          estimate can be made how far the project is over budget.

          Disadvantages

          It’s very tricky to estimate the real Earned Value at a certain point in time. Wrong estimates of this
          value can make a project look like it’s doing a lot better then it really is (or the other way around).

          Usage in Methodologies

          EV management can be utilized to monitor projects where there is planning beforehand when
          assured goals should be reached. This encompasses most thick methods.
