What is the method of critical way?
The critical way (CPM) method is a way to divide comprehensive projects into lists of activities and determinations that are decisive for maintaining the project as planned. This method was developed in the 1950s and was used for complicated programs of the government and private industry, which were for unspecified reasons for schedule plans. A critical way as defined by a method as a number of events called activities that must be completed in the correct order and time.
Construction or other projects may contain thousands of separate activities that occur before the task. Drawings must be created, construction sites must be prepared and many other events must occur before the construction starts. During construction, the foundation and the construction framework must be completed before the start of interior work. Some activities may occur simultaneously, but some have to wait for the previous activities to be completed. All these assumptions are used in the critical way.
Calulations criticismThe timing of the path can be done manually, but can be quite difficult due to many interactions of activities. An easier way to create a CPM is to use a computer table. Since the end of the 20th century, there has been commercial software that creates a critical way as the result of manually entered information about activity.
CPM development requires the use of assumptions because the project usually did not start when the message is created. The process will start the process of a project manager or programmer by writing all known activities from start to finish. Activities are restricted if they exist, which may be the oldest calendar date that the activity can run or the latest date that can be completed. These data limitations prevent motion operations in the model and limited activities are often part of the critical way.
along with any fixed calendarmrains, all activities must be provided fromHad duration or days or weeks needed to complete. Activity may have a long duration, such as placing the steel building or completing the interior, which can cause a critical way to affect. Software programs available for modeling critical ways will show when the activity has been extended for the estimated time. The duration of activity can also affect the critical path if it takes longer than the estimated project time. These results are summarized in the software message when all data has been inserted.
Another function of software for the critical way is to determine how people are used. Each activity can have a resource, person or group, assigned. The activity usually includes the name of the source and how much time in a percentage is needed for activity. Messages can show when the source is needed more than they are available; For example, employees who are needed after 150% of their assigned time. These restrictions allow project managers to move resources as needed to take upIt was inadequate or excessive use of staff during the project.
Complex projects may have cost estimates included in the CPM report. The activities may be stated with estimated completion costs and any additional costs if the activity is delayed or extends the due date. Changes in the critical path resulting in a delay or expansion of the project will have a visible impact on the total cost of the project.
CPM commercial software is often useful because it can easily show changes in a critical path for real -time activities. When the activity changes according to the date or duration, the project manager can enter changes to the project plan and immediately see the effects on the overall project plans and critical ways, sources and costs. The critical way will provide the most accurate results by regularly entering the project for the project, as it continues and changing the activity and duration into actual data and completion of the time.
