Caution !

In addition, most projects

• Involve some activities that are "level-of-effort"
  • That depend on the progress of other activities
  • Or are simply a steady overhead

• If the effort involved in these are more than 5-10% of the total
  • Then the EV results could be skewed
  • I.e. not be reflecting true performance

The solution

• Is to isolate such activities from the performance assessment
