When should PERT be used?
PERT charts are generally used before a project begins to plan and determine the duration of each task—so they don't have to show the actual dates of your project. They also do a better job of showing whether certain tasks need to be completed in order or whether they can be completed simultaneously.
Where is PERT and CPM used?
PERT (Program Evaluation and Review Technique) was first used in the development of submarines capable of firing Polaris missiles. CPM (the Critical Path Method) was used to manage the annual maintenance work in an oil and chemical refinery.
What is PERT analysis used for?
A PERT chart helps a project manager analyze a project's tasks and estimate the amount of time required to complete each task in the project. Using this information, the project manager can estimate the minimum amount of time required to complete the entire project.
Who uses PERT charts?
PERT charts are used by project managers to create realistic schedules by coordinating activities and estimating their duration by assigning three time estimates for each (optimistic, most likely and pessimistic). This makes PERT charts useful when planning projects where the duration of activities is uncertain.
When was PERT first technically used?

How is PERT used in project time management?
In project management, the Project Evaluation Review Technique, or PERT, is used to identify the time it takes to finish a particular task or activity. It is a system that helps in the proper scheduling and coordination of all tasks throughout a project.
What are the 3 time estimates used in PERT?
There are three estimation times involved in PERT; Optimistic Time Estimate (TOPT), Most Likely Time Estimate (TLIKELY), and Pessimistic Time Estimate (TPESS). In PERT, these three estimate times are derived for each activity.
Which one is used in PERT method?

PERT charts are used to diagram the activities required to produce a good, specify the time required to perform each activity in the process, and organize activities in the most efficient sequence.
Is PERT and CPM the same?
Key Differences Between PERT and CPM PERT is a technique of planning and control of time. Unlike CPM, which is a method to control costs and time. While PERT is evolved as a research and development project, CPM evolved as a construction project. PERT is set according to events while CPM is aligned towards activities.
How is pert CPM used in business strategy?
Frequently used together, PERT and CPM both provide valuable tools for project managers who want to coordinate various phases of a large-scale project without sacrificing time or money. Not only is PERT handy for exploratory projects, but it also uses critical paths to determine deadlines regarding certain milestones.

What is pancreatic enzyme replacement therapy and how does it work?
Pancreatic enzyme replacement therapy is the use of medications that contain enzymes to replace what the pancreas is no longer making or releasing. These medications contain proteases to digest protein, amylases to digest carbohydrates and lipases to digest fat. Digestion of protein, carbohydrates and fats helps prevent malabsorption.

You should swallow the capsules with cold or room temperature liquids. Enzymes are deactivated at high temperatures so do not swallow with hot beverages. Do not chew or crush the capsules as they can hurt your mouth. The capsules can be large and sometimes be difficult to swallow. If you are having trouble swallowing the capsules you can:
What if the PERT is not working?
Do not stop taking your enzymes if your symptoms persist - try increasing the dose and contact your medical team for help. The amount of enzymes you need to digest your food may seem high, however a normal pancreas releases 720,000 lipase units during a standard meal.
