Dear sir,

when we update the schedule in particular month, we change the early start & finish dates to actual start & finish dates.

But in the activity form for each activity, there are "Res" & "cost" icons which have "actual to date" options.
Shouldn't we enter the actual cost & actual manhours in this table ?
I think then only we can compare the planned manpower & cost curves with the actual manpower & cost curves.

or is there another way ?

This is continuation to our discussion above.
I have prepared the planned manpower vs actual manpower curve.
My actual manpower graph is falling below the planned graph.

But my schedule is showing delay of 10 days ( negative float).

My manager is saying when our actual graph is falling below the planned,
then we are progressing faster. Why then there is a delay.

Please reply.

Regards

the actual manhours can be updated automatical based on progress the costs can not.

Your manager saying that when your actual graph falls below the planned that you are progressing faster.

That may or may not be true.

If you are talking about manhours then what he is saying is that you are expending less manhours than planned to do the work.

Same hold true for the costs curve. That you are spending less money than originally palnned to install the work.

A few questions
1. How accurate is the planned bugeted manhours & costs
2. How accurate is the actual reporting of the cost and manhours.

On the other hand I can look at the graph and say that you are behind schedule because the estimate was not accurate and that you are not spending enough manhours to perform the work.

Same for cost you can be underspending your planned budget because you are not spending enough manhours. 

If you are behind schedule I would bet its sceniro #2

Dear sir,

thanks for the prompt reply.
But i am very sorry to say that i made a mistake in describing the issue.
Actually, my actual manpower & cost curves are falling above the planned
ones & it is showing 10 days delay (negative float)

then I offer this response

You are inefficient you are spending more manhours than you should do to the same amout of work. Your work factor is over a 1.0 A perfect as planned workfactor or perfromance factor would be 1.0 you are over a 1.0 menaing it is taking you longer than anticipated to do the work. 

You are spending too many manhours and therefore you are OVER budget and will not complete the project within budget or the required time.

In other words you are spending 1.5 manhours to earn 1 manhour.

It's like converting a dollar to a Euro you lose money in the conversion.
you give them $1.00 and you only get back $0.760512  Euro

it takes $1.31 dollars to equal $1 Euro so you are .31 cents or 30% inefficient.
