Can anyone tell me how to assign percent weight for different phase of a project for producing a Project S-curve. I have a percent weight as Engineering:Procurement/Fab:Construction:Commissioning = 25%:15%:55%:5% which I need to assign to each phase S-curve and get a overall Project S-curve. e.g. suppose I have a % complete for engineering as 40%, the contribution it will make to overall progress as 40*25%=10%. Please help its really urgent.
