What is PERT in Project Management? Project Management Guide

Week 8 1 week Sequential G J. For example, if activity 4 to 5 were reduced to 1 week, activities 4 to 8 and 8 to 6 would come onto the critical path. Each Activity should have unique event numbers. Here, it is assumed that the activity duration is fixed and certain. These activities listed in the order of precedence are given below: In this graph jobs are shown as arrows leading from one circle on the graph to another.

Difference Between PERT & CPM

It is aimed to reduce the time and cost of the project. You'll have some extra time to complete the other tasks 5, 6, 7, 8, and 9 if necessary. You can calculate this by starting at the last event and working backwards. Since we have a lot of information about a Normal Distribution, we can make several statistically significant conclusions from these calculations. In these, circles show events within the project, such as the start and finish of tasks. Obviously the 2nd path is the critical path and the project of budget presentation will take this much of time.

In this case, you could look at using two analysts in activities 2 to 3 and 3 to 4. To use it, estimate the shortest possible time each activity will take, the most likely length of time, and the longest time that might be taken if the activity takes longer than expected. It is not necessary to go into the theory behind the formula. All these jobs or activities must be separately listed. For example, software implementation requires the completion of critical activities such as hardware installation, programming, system testing and end-user training. All these relationships between the various jobs have to be clearly laid down. Both have their strengths and weaknesses depending on the kind of project they are being used to manage.

It is very similar to heuristic estimation. Each technique helps organizations to manage risks, mitigate delays and ensure efficient completion of projects. The Work Breakdown Structure, also developed by the U. This is known as the project graph or the arrow diagram. By trying out different project management systems, you can find the tools and techniques that work best for you and your team. These are some of the examples of the use of float to schedule an activity. A method to control cost and time.

In this method, first of all, a list is prepared consisting of all the activities needed to complete a project, followed by the computation of time required to complete each activity. Detailed analysis of supporting modules. This is a strong probability, and indicates that the odds are 16 to 3 that the project will be completed by the due date. It always consists of a horizontal axis that illustrates the time span of your project divided in days, weeks or months and a vertical axis that shows a list of all the individual tasks. The rule is to take the longer bigger of the two Earliest Starts. Suppose, we want to construct a project graph of the simple project of preparing a budget for a large manufacturing firm. The length of the task is shown above it.

Arrows are also sometimes called arcs. The , with its detailed records of time allocated and spent, provided a way for foremen and factory floor supervisors to track progress and measure worker efficiency. Likewise — and perhaps most important — both charts help managers in addition to providing a snapshot of areas that need improving. Week 5 3 weeks Sequential E H. A description of the task is written underneath the arrow. It proved to be a great communication medium by which thinkers and planners at one level could communicate their ideas, their doubts and fears to another level. Having computed the various parameters of each activity, we are now ready to go into the scheduling phase, using a type of bar chart known as the Gantt Chart.

Or, call our project management experts at 855 998-8505 for a free consultation. A network consists of series of activities called paths of network. If used in tandem with the other tenets of project management you could find yourself on the fast-track to project completion. An arrow running between two event circles shows the activity needed to complete that task. Remember, there is zero float on the activities which are identified in critical path.

The evolution of project management Ever since the Industrial Revolution, managers have been seeking better ways to manage projects and increase worker productivity. It allows the project manager who is often responsible for scheduling, and coordinating a series of complex tasks and activities, the ability to monitor the progress of a project. A what-if analysis identifies possibilities and uncertainties related to project activities. We have seen that the project of preparing the budget involves a number of activities. In the diagram, slack is represented in yellow. If the calculations are inaccurate, any delay will create a bottleneck and affect the final delivery date.

By convention, all arrows run left to right. Nordmeyer holds a Bachelor of Science in accounting, a Master of Arts in international management and a Master of Business Administration in finance. After that, the dependency between the activities is determined. The activities are represented by arrowed lines and events by circles. Dependencies are very important in the analysis of the critical path.
