Communicating requirements to project participants is the key to establishing the basis for building a product to "conform to the requirements." Poor communication is often the cause of imprecise specifications that a vendor, subcontractor, or implementation team will be working on. The most critical point at which the communications have the chance for being misinterpreted is _.
A)During the planning phase when little is fully understood about the project's requirements
B)During close-out when all parties are attempting to terminate operations and move all assets
C)At meetings and conferences when the agenda limits the subjects to be discussed
D)The interface between the project team and suppliers of services or products
