In project management, like most things in life, there is no free lunch. If you want to finish sooner, you will have to cut the project scope. If you want lower costs, you have to cut expenses. If you want higher quality, you have to pay more. This constant tug of war is called the Triple Constraint, also known as the Project Management Triangle, or the Iron … [Read more...]
Three point estimating is a technique which utilizes an optimistic and pessimistic estimate to determine the ideal estimate value for a project task. It is a shoe-in for PMP exam questions, which is not likely to change anytime soon. It allows known risks to be quantified and built in to the project budget. Formula There are two generally accepted formulas for three … [Read more...]
Parametric estimating is a guaranteed inclusion on the PMP Exam. This article is assured to give you at least one point (but more likely four or five). Parametric estimating is a project estimation technique whereby a unit rate is used and multiplied by the number of units. For example: A house building project is estimated at $120 per square foot A contractor … [Read more...]
Earned value results are very easy to report to senior management or other stakeholders. Generally the recipient needs some basic training regarding the meaning of the numbers, but this is not a major undertaking. We break down the typical reporting methods into three categories: Small projects Medium-size projects Large projects Small Projects For small … [Read more...]
The VAC is a forecast of what the variance, specifically the Cost Variance (CV), will be upon the completion of the project. It is the size of the expected cost overrun or underrun. In many situations the project manager must request additional funding as early as possible, or at least report the potential for an overrun. The VAC represents the size of this … [Read more...]
The To-Complete Performance Index represents the efficiency level, specifically the CPI (Cost Performance Index) that will make the project finish on time. It can be a powerful indicator because it is generally easy to ascertain if your people will be as productive as the indicator tells you. There are two ways to calculate the TCPI: To achieve the original … [Read more...]
In earned value analysis, the Estimate At Completion, usually abbreviated EAC, is the estimate of the final project cost given the past performance of the project. Thus, it allows the project manager to see what the final project cost estimate is. The EAC is one of four calculations in the Earned Value Management which allow you to forecast the future performance of … [Read more...]
In earned value analysis, the Estimate To Complete, usually abbreviated ETC, is the expected remaining cost to complete the project. It is not the final overall project cost (that's the EAC), rather it is the expenditure from now to the end of the project. It does not include what has already been spent. Thus, it allows the project manager to compare the funding needs … [Read more...]
Earned Value Management is the secret to project success! If you are passionate about having projects finish on time, on schedule, and with all other project success criteria satisfied, you must learn how to use it. Earned Value Management is a project control technique used by project managers to keep projects on schedule and budget. Earned Value analysis gives the … [Read more...]
The real benefit of the earned value method is in the early warning signal it provides. In my previous life at a large engineering company, I saw many project managers get to a monthly billing cycle before they realized the project was behind, and even then they would rationalize it by deciding their project team was going to be more efficient in the next cycle. Suffice … [Read more...]
