EARNED VALUE...
S P P S have international experience with the application of Earned Value Management and can produce EV metrics as required.
Earned Value Management is an approach where actual work and the value of work-completed is identified and evaluated to establish whether the project is on track. It indicates how much of the budget and time should have been spent, with regards to the amount of work done to date.
EVM requires the cost of work in progress to be quantified. This allows a comparison of how much work has been completed against how much was expected to be completed at a given point.
EVM provides an objective way of measuring performance and predicting future outcomes, enabling significantly improved progress reporting and in turn, enabling the Project Management team to make cost, schedule and task duration judgments earlier than would otherwise be the case.
