Consider three contract types we have studied: lump sum, unit price, and cost plus. Provide three scenarios that call for contracts – one for each contract type. In a written narrative, describe your scenarios and address the advantages and disadvantages of the contract type used. Papers should be 3-4 pages long, not including cover page and reference page, typed, double-spaced, written in APA style, with 12-point font and 1-inch margins.
