Man Hours versus Time S Curve

Hanson,

Time S Curve is based on duration, whilst Manhours is based on Labour Resources. In order to develop a "progress curve' based on manhours, you need to resource load your programme, meaning you need to evaluate each activity task and assign resources against it. First you need to know the quantum and production rates involve for each task, then you need to identify resources required and how much resource you need to finish a task.  If you do not know how, you need to talk to your construction team and get an idea concerning the size of a team for each activity task.  Once you have all the data in your hand, you can start resource loading the programme. Whoever did the programme, must have assumed something in order to get the duration, if not, then you need to review the duration based on your production rates and resources and amend the duration if necessary.

Once you have finish resource loading, you can copy and paste the mandays or manhours distribution in P6 to your excel file and produce a progress chart.

Best of luck,

Daniel

Hi Hanson

You can simplify Daniel's excellent advice by creating just one resource called "Hours" and apply that to every task and modelling as advised.

You can allocate the relative trade to the task by using codes - then you can create individual S curves by filtering on the code.

I believe Hanson made it very clear what he is looking for;

Man Hours versus Time S Curve = Cumulative Man Hours on the vertical axis plotted against time on the horizontal axis. The S refers to the shape and gives you the clue to the requirement for it to be a cumulative function of mh values as they accumulate with time.

I do not believe he is looking for a "Duration S", a meaningless curve of no real value at all.

Hanson,

Assuming that you already have a resource loaded programme and your scheduling mimimum time is a day, then probably the data in your P6 programme is in Mandays (Budgeted Labour). To calculate your manhours simply multiply mandays x working hours/day.

Hi Raphael,

Actually, I have seen some companies manage their projects successfully just based on time and experience, especially where labour is cheap and resources is unlimited.

Good to hear from you!

Simple way to create Man-hour versus time.

in the gant chart shwo labour units instead of bars ,copy the total in the excel sheet and draw the s-curve.
