Deterioration in skill level

The project tool is only as good as the effort used to create it, and
the common errors that occur between progress updates refer to progress percentages decreasing between updates, actual dates changing from ‘it started to hasn’t started’ to a ‘revelation that it started six months ago and we forget to record the actual start or record any progress in the six months.’

Other changes are in duration, both original and remaining, the latter appears to be forgetfulness of the planner when using a physical percentage update method which requires both a percentage and number of days to be entered into Primavera. Any error in the progress update can result in producing an unrealistic forecast completion and or critical path.

So with the deterioration in skill level resulting in increasing errors, the project tool for time can not be relied upon when actual data required for the progress updates is incorrect.

Hope this helps !
