10、 duration of the critical pathfar the projectAccording to the CPM Activity on Node diagram above:We could caculate the critical path isSo, the total day would be cost is5+2+11+3=21 (days)REQUIREMENT 2c.(c) What conclusions can you draw from the CPM diagram?We can conclude that the main workload and

11、cost concentrate on the reliability testing. Only to ensure the testing completed on time , the whole project can not be postponed and the projects processing can be balanced by tracing the critical path.REQUIREMENT 2d.(d) Discuss the assumptions, limitations, mid implications for using the CPM as a

12、n approachfor scheduling this project?Critical path method is paramount when attempting to manage the progress of a project. If a portion of the project needs to be shortened, also known as fast tracking, the project manager can order more of the activities to take place at the same time. Using the

13、critical path method, a manager can also increase the productivity of an individual activity by crashing the critical path. This means that additional resources are added to shorten the duration of the activity. Overall, the best advantage of the critical path method is the ability to speed up or sl

17、 What can you conclude about the project duration from analysis of the PERT network diagram?According to analysis the PERT Charts critical path, we know tliat Module decomposition audit and result of audit is the key point of the project. So, if we can control the time spend on Module decomposition

18、audit, it can be narrow the whole projects time.REQUIREMENT 3d.(d) What are the primary concenis that a PM must consider in using PERT for project scheduling?The indetermination that makes use of PERT to carry on an item management to adjust main considerated time, particularly lie in to time of con

20、ct management process is to identify risk and control risk. Through the transfer of risk to prevent, avoid, reduce and use of five strategies for effective risk management. In any project there is a risk, risk is a kind of uncertainty, the risk may lead to project failure, effective risk management

21、can reduce this possibility. However, the risk of project feilure are not necessarily factors. So risk management can not completely eliminate the possibility of project failure. But can effectively reduce this possibility.REQUIREMENT 4b.(b) identify prima/y sources cf risk inherent in this projectT

22、he risk of the project can be broadly defined as the source of the following:1. Technical risk, lack of training, methods, tools and technical understanding is not enough, not enough experience in the field of application of new technologies and development methods, the method does not work correctl

23、y2. Cost risk, though company officials promised regardless of cost, but did not explicitly limit the specific costs3. Human resource risk, project organization and division of responsibilities is not scientific, the absence of other staff4. Communication-related risks, including with customers, executives and team members a common problem among5. Time or resources available on the date of the estimation error; on the distribution of the floating lag time or poor managementREQUIREMEN
