Percentage Progess checking

To what "system" are you referring ?

Progress can be either a measure of time or effort (manhours). Since time and effort are not linear across the span of a project, I prefer and recommend that you measure progress in terms of manhours.

You can only qualify the overall percent complete if you can qualify the degree of accuracy in the estimating. Even then, you are assuming that the remaining schedule will stay within the margin of error recorded up to that point in time. This may or may not be a safe assumption.

If you are using P3, there is a simple way to note project percent complete (using remaining durations.) Just run a CPM report. At the bottom (around the fifth line from the bottom, I believe,) there will be a listing of Project Percent Complete. Good luck!

Using duration as weighing factor, you can check by computing manually using the formula (Sum of OD - Sum of RD)/Sum of OD.

OD - Original Duration
RD - Remaining Duration

For resource units the formula is AQ/BQ

AQ - Actual Quantity
BQ - Budgeted Quantity

For cost, the formula is AC/BC

AC - Actual Cost
BC - Budgeted Cost

You can check all these data by printing reports.

Thank you all for the reply

Well what I want to calculate is the overall percentage progress of the total project which P3 gives us when we summarize the whole project

Cause for that we are relying on the system.

I agree there could be weightage factors like Cost,Qunatity
but say that for a simple Schedule with no resource planning how would you calaculate the overall progress or how does the system calculate the overall summarized progress.

what do you mean by "system"???

I think by "system" he means the software (P3 in this case).

Without resource planning, you are limited to measuring time. This is not a useful measure IMHO.

However, for each task, you can calculate:

Hours Elapsed / Hours Scheduled * 100 = Percent Complete

When calculating percent complete as a measure of time, each task is weighted the same, so average the percents complete across all tasks to find the total.
