You are a general manager of the large construction project. Contract has both financial incentives for finishing on time or early also large penalties if project is completed late. To get project done on time or early that project planning using formal timeline is essential. You ask project manager to address following problems:

1. In terms of developing timeline, what do you mean by critical path of PERT chart?

2. As project manager you know that fastest possible time project can be completed is known as critical path. This implies that any delay in any step of projects critical path, will hence delay overall project. On a particular project, step B is part of critical path; step C and D both are not. Suppose that all of these steps, B, C, and D are at risk of being delayed due to some issue (could be lack of people, lack of materials, equipment downtime - it makes no difference).

How would manager go about prioritizing correction of problem existing in B, C, or D? Should manager address issue in step B first, step C first, or step D first; why?

3. Once repair is finished in step #2, how would go you about prioritizing repairs at other two steps?
