Welcome to the PMP Exam Tutorial! We hope you will take something from these pages that will help you pass the exam. Each page of the tutorial is dedicated to one knowledge area. On each page the processes that are part of the knowledge area are described and their relationship to the overall project model are... [Read More]| ProjectEngineer
Top Down estimating is a project estimating technique whereby the overall project is estimated first, and individual tasks are apportioned from it. You start from the top of the pyramid and work downwards. This type of project budgeting usually occurs when there is a fixed budget and/or the scope of the project must fit within...

Project estimating is one of the most important aspects of project management. By their very nature, projects have fixed budgets and their owners want to know how much they will cost. Hence, project estimating begins prior to project initiation and estimates are usually updated at important project milestones. A Rough Order of Magnitude estimate, often...

In 1986, the NASA Space Shuttle Challenger exploded spectacularly upon take-off in front of one of the largest live TV audiences in history (to that time). The investigation concluded that several tiny O-rings that sealed the rocket booster to the fuel supply failed. These O-rings were about 1 foot in diameter. Just like the tiny...

Bottom up estimating is the project management technique of estimating individual tasks and then combining them into an overall project estimate. Often the individual project team members who will be performing the task provide the estimates, because they are in a better position to estimate a task that they will be working on. Types of...

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...

Analogous estimating uses the actual data from a previous project as the basis for estimating the current project. For example, the previous fence cost $75/foot therefore this one should cost about $100/foot. Many different variables can be compared, such as: scope cost budget duration Measures of scale: Size, weight, length, etc. Work units: Number of piles driven,... [Read More]| ProjectEngineer
