What is the evaluation and program control technique?
Program evaluation and control technique (PERT) is a project management system that resembles a dynamic development of interconnected processes. It is used to coordinate the diversified elements of the project and their respective effects on costs, time and each other. The evaluation and control technique provides an adaptive overview of these dynamic elements than traditional graphs of static projects and time axes. The evaluation and review technique of the program, originally developed for extensive military-industrial projects, is used in large and small organizations that require coordination of resources, teams, costs and deadlines to achieve reserved results. In practice, the implementation of tasks depends on the ongoing project requirements, team decision -making and other external restrictions. The primary task in the development of the PERT plan is to determine critical activities on which all other Activitan depends. This is sometimes referred to as a critical way (CPM) method.
The graph itself consists of three main elements - nodes, darts and roads - assembled in various tree formations. Nodes identify key elements of the project such as department review, research and development or public launch of a new product. These nodes are associated with the arrows and the arrows determine the sequence of the phases to which the project will go. Some nodes will have more arrows dependent on their results, with decisions or perhaps current activities. The advantage is that the observer can immediately see which project elements will be influenced directly by the processes of the node.
The project path is not necessarily linear or static, as one could find in neat vertical stripes of Gantt's chart. The chain is just as strong as the weakest link, so the graph using the technique of evaluation and control of the program is only as current as its longest way. This path represents a minimum timeframe to complete the project; Therefore, it is called a critical way. This path will be an area noJvíce concern for a project manager who deals with unforeseen delays and unexpected costs.
6 By clearly assessing these nodes, the manager can better recognize potential problem areas and processes with the introduction of "slip" into even highly complex projects. By comparing paths with less meaning with a critical way, managers can identify not only certain milestones and terms, but also the "Slack" areas that provide more torque rooms.by forcing project managers to create a firm understanding of the critical elements in the project and supervise the dependence of the relationship between the evaluation and evaluation of the program among the nodes provides a clearer understanding of the complex project. This could lead to greater team coordination, more efficient communication activities and a more efficient process or object evaluation. Computers help analyze more complex plans. Due to the clear times and goals of the initial/goal they process known elements using algorithms to perform as possiblemore positive forecasts.
Given the complexity and dynamic nature of Pert planning, the best results with proven industrial methods can be found, where processes and expectations are generally known. Unforeseen circumstances or difficulties, the range of completion and butterfly effects sometimes make a short job of any well -laid plan. A well -prepared project manager can use the evaluation and program control technique not only to coordinate a huge number of elements, but also to minimize the most likely area of risk to achieve a successful project outcome.
