You are the Project leader of one of the five (5) most important government projects in one country. Your objective is to complete the project on time and with no critical deviation in cost. You only have the project control team from your own company. The teams to develop the projects are from the following three subcontractors: 

• Contractor 1. You have worked with it, and you consider it a responsible and capable contractor. 

• Contractor 2. It is the first time you will work with them, and it is a new company with no previous background. 

• Contractor 3. You worked with this one two years ago, having a terrible experience, and you have information that they have not improved since then, but no other contractor was available for the job.
