You work for a large engineering design firm that receives a contract to build a new multi-level sports and fitness complex. It’s a lucrative contract, but the hitch is that the project must be completed on a tight time frame with no cost overruns. In this situation, which of the following might your company do to best advantage?
A. Assign a single team to the project and involve the contractors as part of the in-house team.
B. Do the design work in-house and then have the design team contract out the construction work to the lowest bidder, to be managed by a team the contractor assembles.
C. Assign separate teams to the design phase, choose the best design, and then contract out construction to the bidder that best balances low cost with high qualifications.
D. Do the design work in-house and then have the design team contract out the construction work to the bidder with the best qualifications, to be managed by a team the contractor assembles.
