Create an Enterprise Project Type with Project Server 2013

Starting with a definition, what is an Enterprise Project Type (EPT)?

This is the definition I found on office.microsoft.com website:

In Microsoft Project Web App, an enterprise project type (EPT) represents a wrapper that encapsulates phases, stages, a single workflow, and Project Detail Pages (PDPs). Each EPT represents a single project type.

The schema below explains what an EPT contains and the hierarchy of each elements:

From bottom to top, to create an EPT, you first need to create Enterprise Custom Fields, Project detail pages (that might contains custom web-parts), workflow (with phases that contain stages) and finally the EPT.

Using PERT to calculate task duration in Microsoft Project

What is the PERT technique?

Following the definition found in Wikipedia, "the Program (or Project) Evaluation and Review Technique is a method to analyze the involved tasks in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project."

For those who passed or are preparing for the PMP exam, you should know the famous formula to calculate the expected duration of a task. This is also known as the "three point estimate".

Calculation of the expected time (TE): the best estimate of the time required to accomplish a task, accounting for the fact that things don't always proceed as normal (the implication being that the expected time is the average time the task would require if the task were repeated on a number of occasions over an extended period of time). The formula is:

TE = (O + 4M + P) ÷ 6
