Expert Use of PERT in Software Project Management

A software project is a complete software development process, from requirements collection through to testing and maintenance, performed according to the method of execution within a specified period of time to achieve the desired software product.

Software project management includes many activities, including project planning, software product scope determination, multi-cost estimating, scheduling of tasks and events, and resource management. Software project management may include:

  • Project plan
  • Scope Management
  • Project Estimate

PERT in software project management is a planning tool that calculates the time required to complete a project.

PERT represents the program evaluation review technique. PERT charts are tools for planning tasks within a project - it is easier to schedule and coordinate the team members who complete the work.

History of PERT Chart

The PERT chart was created in the 1950s to help manage the creation of US Navy weapons and defense programs. Although the PERT is being introduced into the Navy, the private sector has also triggered a similar approach called the "critical path."

In 1957, the NAvy special projects office created a PERT chart to assist Polaris nuclear submarine project.

Since then, it has found a home in a variety of industries, even the Winter Olympics in Grenoble in 1968.

The PERT in approaching the critical path came about the same time, developed from the scientific management created by Frederick Taylor, also known as Taylorism, which was later perfected by Henry Ford. But the use of the term critical path came from DuPont, who also developed the method in the late 1950s.

PERTs are similar to critical paths because they are used to visualize the timeline and the work that the project must do. However, with PERT, you can create three different time estimates for your project: estimating the minimum time each task will spend, the most likely amount of time, and the maximum time a task can take if things are not scheduled .

The PERT is calculated back from a fixed end date because the term of the contractor is generally not mobile.

How to Create a PERT Chart

When you create a PERT chart, the task or activity is indicated by an arrow on the chart. The milestone date of the project is represented as a node or circle.

A PERT event is a point that marks the beginning of one or more activities.

There are also some predecessors, they happen before some even numbers and a follow-up event, which happens naturally.

PERT has four settings for the time required to complete an activity in software project management.

  • Optimistic time is the shortest time to finish an activity.
  • Pessimistic time, the longest time to finish an activity.
  • The most likely time, this is the best estimate of the time needed to complete an activity, assuming there are no problems in software project management.
  • Expected time, which is the best estimate of the time required to complete a software development task or activity, assuming a problem.

Steps to Implement the PERT Chart

Determine the order and duration of the tasks that must be taken to complete the project.

Create a network map with arrows representing activities and nodes as frames.What is the critical path and possible slack?

PERT charts can be used before the project runs. They are a great way to help you make simple and accurate software project management estimates. Estimates may be very optimistic or pessimistic, but using the PERT chart will find the estimate more realistic.
