The PERT distribution assigns very small probability to extreme values, particularly to the extreme furthest away from the most likely value if the distribution is strongly skewed. [ 6 ] [ 7 ] The Modified PERT distribution [ 8 ] was proposed to provide more control on how much probability is assigned to tail values of the distribution.
The PERT distribution is a special case of the four-parameter beta distribution. The uniform distribution or rectangular distribution on [a,b], where all points in a finite interval are equally likely, is a special case of the four-parameter Beta distribution.
PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F). The program evaluation and review technique ( PERT ) is a statistical tool used in project management , which was designed to analyze and represent the tasks involved in completing a given project .
The three-point estimation technique is used in management and information systems applications for the construction of an approximate probability distribution representing the outcome of future events, based on very limited information. While the distribution used for the approximation might be a normal distribution, this is not
Beta distribution is a combination of probability theory and statistics, most commonly used in project management for time allocation and to analyse random variables. Critical path drag is a project management metric used to schedule analysis and compression in the critical path method of scheduling.
