Executive Summary: Pi??ata worked in IT department of diversified firm. Firm increment budget by 10 percent to all activity because all project were coming to late while people was working too hard and wants to relief. Result this approach failed, after this firm decide to give extra time and 10 percent for complete project on given time schedule but overall result failed. Nothing improved and project continued late from actual date.
Key Problems: The firm doesn’t have project buffer and wait for coming project. The firm’s guideline has squeezed down less than 50 percent. Employees who have worked more than six projects are quite from this firm because no hope of things getting better. Employees have tired due to hard work and day to day work with tight project deadline. Manager did not submit project work down stricter which show project budget, timeline, resource allocation and reporting schedule time to time as need.
Methodology: Pi??ata has passed PM exam and gave surprise to IT department, she represented her friend ideas to her manager like squeezing estimates and explained that CPM procedure by allocating the minimum amount of time to a task, so that the task stays regent and the resource will be fully dedicated on the task until it is done, also try to keeping a critical chain critical by making sure that the resource will be available at the end of the previous task(s) using buffers to counter variances In time costs. Seed properly, the Critical Chain approach is an extremely powerful means of gaining more predictability, productivity and speed from your project plans. The Five Focusing Steps or tasks of action which are applicable to any physical system are described below: 1 . Identify the system constraint. 2. Exploit the system constraint. 3. Subordinate everything else to the system constraint. 4. Elevate the system constraint, and 5. If, In the previous step, a new constraint has been uncovered, repeat the process.
She detail explained by using the process of Critical Chain Method, projects can be completed more quickly and with greater scheduling reliability. The difference between traditional and Critical Chain scheduling is in how uncertainty Is managed. In traditional project scheduling, uncertainty Is managed by padding task durations, starting work as early as possible, multi;tasking, and focusing on meeting commitment dates. The following bullet points illustrate some of the problems associated with traditional project scheduling: Padding task durations (providing worst-case estimates) Is done to ensure a high probability of task completion.
Starting work as early as possible, even when not scheduled, Is a response to worst- case estimates. When workers give worst-case estimates, they don’t expect to stay 1 OFF switching between them. The result is that everything takes a long time to complete and very little completes early. Firm’s Analysis: She told manager that we use CPM and will improve the project plan by ensuring hat it is feasible and immune from uncertainty or statistical fluctuations. It does this by aggregating uncertainty into buffers at the end of activity paths.
The Project Buffer protects the overall project completion on the critical chain path, and Feeding Buffers protect the critical chain from path merging. Buffer Management enhances measurement and decision making for project control. CPM implements required changes in resource behaviors, including elimination of date-driven activity performance and multitasking. CPM improves the focus of the Project Manager and performers. Projects that use CPM have a greatly improved record of schedule, cost, and scope performance.
CPM projects are normally complete in less than one half of the time of projects using previous planning and control methods. Action plan: Reduce the impact of changes on work already performed. Delay the project cash outlay, and give the project a chance to focus by starting with fewer simultaneous activity chains, allowing. The project team and processes to come up to speed, the improved measurement system for Critical Chain Project Management. Use buffers (that is, time) to measure activity chain performance. Size the buffers based on the length of the activity chain they protect.
Buffer sizing uses the uncertainty in the duration of the Critical Chain activities to size the Project Buffer. Likewise, uncertainty in the duration of the feeding chain activities determines the size of each Critical Chain Feeding Buffer. CPM sets explicit action levels for decisions. The decision levels are in terms of the buffer size, measured in days: 1. Within the first third of the buffer: no action. 2. Penetrate the middle third of the buffer: assess the problem and plan for action. 3. Penetrate the third: initiate action.
