EAC is what you should really be interested in because it is the only constant in a moving project. Therefore, these extended EV techniques must be considered in the same realm of accuracy as topdown estimating. They are useful, but only if you recognize the limitations and know what you are doing!But, as we said at the beginning, it is a lot more difficult to do in practice – and involves a significant amount of work. But, let39。s Project Budget responsibility? Once this Approved Project Budget is released to the project manager, a reverse process must take place to convert it into a working control document. That is, the money available must be divided amongst the various WBS WPs that, by the way, have probably by now been upgraded! This results in a project execution Control Budget or Project Baseline Budget, or simply, the Project Budget. In some areas of project management application it is referred to as a Project Cost Plan.? On a large project where different corporate production divisions are involved, there may be a further intermediate step of creating Control Accounts for the separate divisions, so that each division subdivides their allocated money into their own WBS WPs.? Observe that, since the total Project Budget received formal approval from Executive Management, you, as project manager, must likewise seek and obtain from Executive Management, via the project39。s project manager and will likely not include any of the allowances. An exception might be the contingency allowances to cover the normal variations in work performance.? The net sum thus arrived at constitutes the project manager39。ll e to in a minute. Either way, the result is an estimated cost of the total work of the project.Note: that project risk management planning is an important part of this exercise. This should examine the project39。s Concept Phase? Every project starts with someone identifying an opportunity or need. That is usually someone of importance or influence, if the project is to proceed, and that person often bees the project39。s ability to effectively control project costs.FootnoteI am indebted to my friend Quentin Fleming, the guru of Earned Value, for checking and correcting my work on this topic.The Business Case and Application for (execution) FundingIt is important to note that project cost control is most effective when the executive management responsible has a good understanding of how projects should unfold through the project life span. This means that they exercise th
