A project that you are managing is into six months of its accomplishment andthe planned duration is also six months. You are now reviewing the projectstatus. The actual cost of Activity A and B are RM 200,000 and RM 100,000respectively. The planned value for Activity A and B are RM 180,000 and RM80,000 respectively. The Activity A is 100% complete whereas Activity B isonly 75% complete. (a) Formulate the problem to determine whether the project is on-time and on-budget after six months using the Earned Value Analysis (EVA) method. (b) Generate the expected “cost at complete” and “time at complete” to finishthe project at this pace. (c) Present two initiatives to be undertaken by the project manager to improvethe situation based on Q4(b).

The North Carolina Department of Transportation is undertaking a construction project to widen a large section of interstate highway near Charlotte, NC, which includes the construction of a number of new bridges, interchanges, and overpasses. The first step in the project is the appointment of a project manager and the development of a project team, some of which will be departmental employees and others will be private consultants and operatives. The team of a project of this size also requires a large support staff with varying technical skills. Once the team is selected and the staff is in place the first task is to select a primary contractor to manage and oversee the actual construction. The following table gives the standard activities required for the planning and scheduling of this process.

The client of a project has requested the project team to crash 8 hours of time. The table below provides the necessary information about the possible project crashing. (a) What is the crash cost for 8 hours of time-savings? (b) Assume the team calls the client and asks for a project extension, reducing the amount of time they need to crash. The project team has a $20 crash budget. Is the budget sufficient to crash 4 hours of time?

A project is scheduled to complete in six months duration. There are two activities in the project. The actual cost of Activity 1 is SAR 300,000 and that of Activity 2 is SAR 200,000. The planned value of these activities is SAR 280,000 and 150,000 respectively. On reviewing, the current project status is Activity 1 is 100% completed and Activity 2 is only 75% completed. (i) Perform the earned value calculations of the above project scenario and fill the given table. Activity Month 1 Earned Value Planned Value Actual Cost Cost Variance Scheduled Variance Cost performance Index Schedule performance Index (ii) What do you infer about the project schedule and cost based on your calculations?
