Program Evaluation and Review Technique/Critical path method Essay

Project management triangle is the symbol that represents the money, date and setting items in a project, which has been modeled by Harold Kerzner. Given the wide align of project management tools available, the key to selecting the right one is to on a lower floorstand that diametric tools atomic number 18 needed along the different stages of a project manners cycle. Graphical displays such as gantt-charts usually make the information behind to identify and we can easily use it for tracking cost, schedule and performance. Gantt charts are used for exhibiting program progress or defining specific toy required to accomplish an objective.They often include such items as lean of activities, activity duration, schedule dates, and progress-to-date. PERT also is used which stands for Program military rating and review technique. It is also called critical path method. It is an event-oriented mean aid, usually computerized used to estimate project duration when there is hesitanc y in estimates of duration times for individual activities. It helps the project team to show the activities that must be completed to implement a decision.A bend Breakdown Structure is a results-oriented family tree that captures all the work of a project in an organized way. WBS breaks down project into major(ip) modules by breaking down into activities and, finally, into individual tasks. Identifies activities, tasks, resource requirements and relationships between modules and activities. The strand benefit of WBS is its effective aid in the planning process. As WBS evolves, it becomes easier to revise and update plans. Responsibilities can be assigned at different points of the WBS hierarchical tree, both managerial and technological.The primary(prenominal) rule behind crashing activities is to analyze the normal activity costs and costs under maximum crashing and to find the shortest times with crashing. And we must realize that new paths whitethorn become critical and mak e sure that all of the alternatives are true. And the main rationale to use PERT or CPM is the approach of timing. With CPM, we define that activities render certain completion times with minimal deviations. With PERT approach, we assume that activities gull average completion times with a standard deviation, therefore time is an uncertainty.
