at this stage it might not possible … The optimistic schedule is 12 weeks, the most likely schedule is 16 weeks, and the pessimistic schedule is 26 weeks. Your Analysis … We wish you good luck with your Project Management Certification journey! Accurate time estimation is a skill essential for good project management. WE ARE CONNECTED ~ Follow us on social media to get regular updates and opinion on what's happening in the world of project management. You typically develop a budget in stages — from an initial rough estimate to a detailed estimate to a completed, approved project budget. Project charter 3. ANSWER: FALSE *13.45 Gantt charts contain information as to the time taken by each activity, but not the sequential dependencies of the activities. The Project Schedule is the Platform for Both Schedule Risk and Cost Risk Analysis. I always tried to find the answers in the books but estimation is difficult subject to understand. To compare the simple paybacks or internal rates of return between projects, an estimate of the cost of each project is made. Identifying risks The inputs of cost management include, 1. Once we know how long each activity will take, we can use this information to understand the duration of the project. Time estimates often determine the pricing of contracts and hence the profitability of the contract/project in commercial terms. Years ago I worked on a large effort to reengineer a distribution center for a major retailer. In a usual scenario, the project estimate is done by conducting estimation workshops with the stakeholders of the project, senior team members who could give valuable inputs to the estimation exercise. If you underestimate time, not only do you miss deadlines, you can also put other people under unnecessary stress. Creating Work Breakdown Structure (WBS) 2. Also, if the project deadline is defined as a certain day (as it almost always is) then project control will be very complicated if you’re tracking against some other unit. 7. Assumptions 4. Contact with other customers, suppliers and contractors. Estimate the time to complete each sub phase. The dotted line shows a steady expenditure over the lifetime of the project. An important aspect of variance analysis is Once more detail is learned on the scope of the project, this technique is usually followed where high-level chunks at the feature or design level are estimated and are decomposed progressively into smaller chunks or work-packets as information is detailed. The best way to review the job is to just list all component tasks in full detail. To begin with, estimate the time needed for each task rather than for the project as a whole. Teamwork isn't something that just happens. Indirect Cost. The learning curve is another factor that should be taken into consideration. Critical Path Analysis The work needed to complete the project needs to be broken down and all activities need to be defined. Also make sure that you have allowed time for: These factors may significantly lengthen the time and cost needed to complete a project. In a usual scenario, the project estimate is done by conducting estimation workshops with the stakeholders of the project, senior team members who could give valuable inputs to the estimation exercise. Broad participation in preparing estimates 3. In the (unlikely) absence of any control measures or spontaneous changes in individual behaviour, we would expect a peak in mortality (daily deaths) to occur after approximately 3 months (Figure 1A). This technique gives more accuracy in project estimation. Variable Cost. If a project needs to be completed repeatedly, it is obvious that it will be completed faster the more times it is completed.
