How to use the % completion in P6

percentageThe difference between the following percent complete types in Primavera 6

1) duration % complete
2) schedule % complete
3) performance % complete
4) activity % complete
5) Physical % complete

The easiest way to understand the differences between the various percent complete types in Primavera is to go to the menu then check them. Then bring up your column fields & you will be able to see the differences between the way the various percent completes are calculated.

Percent Complete Type

The activity percent complete type is one of “Duration”, “Units”, or “Physical”. The percent complete type controls whether the Activity % Complete is tied to the Duration % Complete, the Units % Complete, or the Physical % Complete for the activity. Set the percent complete type to “Duration” for activities which are duration driven, for example, administration tasks and training classes. Set the percent complete type to “Physical” for activities which are work-product driven, for example, creating a document or a product. Set the percent complete type to “Units” for activities which are work effort driven, for example, providing a consulting service.

1. Duration %

The percent complete of the activity duration. Computed as ((Planned Duration – Remain Duration) / Planned Duration) * 100. Always in the range 0 to 100. The planned duration is taken from the current plan, not from the current baseline.
Duration % of Planned The activity actual duration percent of planned. Computed as (Actual Duration / BL Duration) * 100. The value can exceed 100. The BL Duration is the activity’s at complete duration from the current baseline.

2. Schedule %

Complete The Schedule % Complete specifies how much of the activity’s baseline duration has been completed so far. Computed based on where the current data date falls between the activity’s baseline start and finish dates. If the data date is earlier than the BL Start, the Schedule % Complete is 0. If the data date is later than the BL Finish, the Schedule % Complete is 100. The Schedule % Complete indicates how much of the activity duration should be currently completed, relative to the selected baseline. Note: Summary Schedule percent complete when displayed on an organize band, will ALWAYS be calculated as (BCWS* 100) / BAC, regardless of what earned value technique is selected for the activity’s WBS.

3. Performance %

Complete Performance percent complete is used to compute earned value and may be based on the Activity % Complete, on the 0/100 rule, on the 50/50 rule, etc., depending on the technique for computing earned-value percent complete for the activity’s WBS. The Performance % Complete specifies what percentage of the activity’s planned worth has been earned so far.

Note: Summary Performance percent complete when displayed on an organize band, will ALWAYS be calculated as (BCWP * 100) / BAC, regardless of what earned value technique is selected for the activity’s WBS.

4. Activity %

Complete The activity percent complete. This value is tied to the activity Duration % Complete, Units % Complete, or Physical % Complete, depending on the setting for the activity’s Percent Complete Type, which is one of “Duration”, “Units”, or “Physical”. Always in the range 0 to 100.

5. Physical %

The activity physical percent complete. The physical percent complete reflects the actual progress made on the activity’s work products so far. Physical percent complete can be manually entered by people familiar with the status of the activity’s work products or it can be based on the completion of assigned Steps. Always in the range 0 to 100.

What about Rolling up the same at WBS levels (excluding Performance % Complete which is purely connected to the WBS – but needs additional updating to the new Milestones under the WBS)?

There were two ways as in P3:

1) Duration 2) Weight (Cost or Units)

Duration Case:

Item Duration %
WBS 18d 20% = 100*(0.5*5 + 0.1*15)/20

Activity 1 5d 50%

Activity 2 15d 10%

Cost or (Weight) Case:

Item Duration Cost %
WBS 18d 1500 36.7% = 100*(0.5*1000 + 0.1*500)/1500

Activity 1 5d 1000 50%

Activity 2 15d 500 10%

P3 remained “P3” while this new enterprise-wide software is now called either P5 (short-hand for Primavera Project Manager™) or P6™ (for Enterprise Version 6). These two options were simply available in P3 …P6 is the most complex and flexible scheduling software to date. But now in P6 it is done that way (exactly copied from the manual):

[(Summary Current Original Duration – Summary Remaining Duration) / Summary Current Original Duration] * 100
