Now let s see how Schedule % complete works in action on a sample Primavera P6 plan. Pulling Schedule % Complete together for WBS and Activities The following diagram shows Schedule % Complete of a sample WBS Element with two Activities in different Data Dates. Total Baseline Costs (BAC) To summarize, Schedule % Complete for Activities is based on time, while its value for WBS Elements is based on costs. Baseline Costs before the Data Date (PV) 3. 2 P a g e Reference: Ĥ The above descriptions show that the Schedule % Complete of the WBS Elements depend on the following: 1. These costs are aggregated to the WBS level, and the time-phased cost of the WBS Element will be calculated automatically. Oracle Primavera will show you how costs are then planned for each day of the Activity. Resource assignment hours and costs are, by default, spread uniformly over the duration of the activity (but you may apply a Resource Curve to alter this). Does not factor in any Activities Schedule % Complete values How Schedule % Complete is calculated for WBS Elements When you assign resources and expenses to activities, each activity will receive a calculated Total Cost. However Schedule % Complete for WBS Elements is: 1. As you saw before, the Schedule % Complete of the Activities is time-based. But, as in scenario 2, the three Activity values which are all less than 50% could never have a weighted average more than 50%. You might expect it to be the rollup value of the underlying Activities (a weighted average for example). How is Schedule % Complete calculated in each scenario? A WBS Element s Schedule % Complete is calculated in a completely different way. Scenario 2 In this scenario, the Sample WBS Element has three Activities with Schedule % Completes less than 50%, but the Schedule % Complete of the WBS Element is 75%. Let s start by reviewing 2 possible scenarios: Scenario 1 How are these calculations possible? The Sample WBS Element has three Activities, they all have Schedule % Completes greater than zero, but the value for Sample WBS Element is 0! Before I reveal the answer, here s a contrasting scenario. Activity s Baseline Finish Schedule % Complete for WBS Elements And now, the story of how Schedule % Complete is calculated for WBS Elements. For Activities, Schedule % Complete is strictly calculated based on: 1 P a g e Reference: Ģ 1. Here s a formula to calculate Activity Schedule % Complete: Schedule % Complete (Act) = ( ) / ( ) The following diagram shows the Schedule % Complete of a single Activity for different Data Dates: And that s all for the activities it has nothing to do with the current schedule, the resource curves, the costs, etc. Otherwise, Schedule % Complete would show what percentage of the Baseline duration is passed by the Data Date. When the Data Date is earlier than the Baseline Start date, Schedule % Complete is zero, when it s after the Baseline Finish data, Schedule % Complete is 100%. It s simple just take a look at the following figure. Schedule % Complete for Activities And now, let s start the story with how Schedule % Complete is calculated for Activities. This is the source of the most common problems people have with this field. The second thing is that this field is calculated differently for Activities than for WBS Elements. As a result, it is calculated based on the Project Baseline and the Data Date it has nothing to do with the current schedule.
The first thing to mention is that Schedule % Complete deals with planned progress. Two important products of maintaining schedules are planned progress and actual progress of a given time you want to know how much you ve done so far and compare it with how much you were supposed to do so far, in order to reach project targets. 1 Schedule % Complete in Primavera P6 Schedule % Complete is one of the many percent completes you have in Primavera P6 and we re going to have a complete look at what it is and how it is calculated.
