I’m after some thoughts on Earned Value.
At the moment my Contractor progresses his progressed baseline each month. This will include updating % and most likely extending the Original duration of a task.
For this months Cost value report, I have asked the contractor to justify his % Complete Earned, for the cost code of EG; which is essentially the pilling works, and the work associated with it.
Within his programme, he has divided the east side into Zones, example EG1 being, Ground works in zone 1. These work activities as covered with level 3 tasks, resource loaded ( no cost). Summarising these activities is a hammock, which contains the cost for the EG1 works..
What the contractor does each month is to progress these activities and stretch the duration’s to match the Forecast finish date that he requires to show. Then to summarise by EG1, to replicate the summarised data on the Hammock, for his BCWP for that Zone.
The problem we have is that since P3 summarises the Level 3 activities by the formula [(Sum of the Original Duration - Sum of the Remaining Duration) / Sum of the Original duration ] x 100, gives a negative percentage. Since the majority of the duration’s are now greater than the OD, when summarising, the roll up shows zero %... So, whatever the contractor displays in his Hammock, as %, cannot be backed up. (unless he recalculates his OD, by calling it the sum of OD + RD)
From this, should the contractor be progressing the baseline, with % complete only, without the influence of the RD being greater than the OD?
What are your thoughts, and what have you seen other contractors use?
