Prepare a RFP for a real-world project that you have participated in. Optimally, this would be an actual business or government project. But if your experience is limited, you may develop the RFP for a relatively complex personal project that would involve interaction with at least one contractor.
Consult the relevant sections of Chapter 2 and Chapter 3 in the Gido and Clements textbook for information about preparing a RFP.
