CPM or Critical Way Method is a step-by-step task management way to identify activities on essential path. The approach should be to schedule a project where we breakdown a project into tiny tasks and display all of them in the form of a flowchart and then calculate the project timeframe. CPM is the longest collection of duties in a task plan that must be completed promptly in order meet the deadline, in the event that one activity gets postponed the whole project gets delayed. It was designed probably about 1950 by Morgan R. Walker Wayne E. Kelly Jr. The critical path method originated at a personal sector although its equal PERT (Project Evaluation Review Technique) was developed by the ALL OF US navy likely around the same time. This process was presented as a partnership between Remington Rand Corporation and DuPoint Corporation. This technique or protocol is a project modelling strategy where we can schedule a couple of project actions. CPM can be utilized with a wide array of projects the not only limited to software development it can be used pertaining to maintenance, studies, product development, production, car service and so forth So if we have any kind of project with independent actions and mathematical calculations can use this protocol to spend resources and understand the booking of work in greater detail. The some main parts that should be taken into account while designing a CPM are as follows:
- We should have an obvious work breakdown structure with all the activities observed properly in ascending purchase.
- We must calculate each activitys time and the source that it is going to require.
- We need to be manifest of the end milestone and also the end stage of each activity and the previous or last activity.
- Once we are done with the above steps we can get a clear thought between the habbit of one activity on the other we are able to identify which will activity to offer more concern and determine the activity based on priority.
Therefore in CPM we need to stick to the above measures in order to obtain full precision. The above procedure helps us to identify the critical actions and essential path. The CPM identifies tasks which can be critical and arranged in order where the project is supposed to be finished. Once we have done that their easier to discover the longest time it will require to complete a project and the shortest the perfect time to complete a project. We can improve our job timeline depending on the critical path technique. Some assignments may have one critical route while others may have multiple critical pathways.
The various advantages of Important Path Approach are as follows:
- aHelps us to comprehend the essential activities of the project.
- Helps us in imagining the activities of the project so that while presenting we can make the client or perhaps the project director understand the tasks resources and timeline in a better way. (Its simpler to visualize than imagine).
- CPM not merely helps us to identify solutions and responsibilities but it also assists us to identify the total period that the job is going to decide on complete.
- Helps the project manager predict and understand the time that a job is going to decide to use complete and the parts where the project achievement delayed helping him to change and set aside free float (free assets and time) to that particular node/activity to meet the project deadline.
The various applications of Critical Route Method happen to be as follows:
- It was first used in missile-defense construction job.
- It is used for software and hardware product.
- Used in RD for most of computer software.
- Utilized in RD to get software and hardware development.
