Quаrters, Inc. is а cоmpаny that sells maps оf the U.S.A. that have pre-fitted hоles corresponding to the recently release quarters with state emblems on the back. The maps are display cases and collectors guides for families or individuals participating in the program. Six months ago the marketing manager requested a new system that would allow retailers of the maps to order them in packs of fifty over the Internet. Three retailers are local and have volunteered to participate in a half-day evaluation of the new system. The new web-based system is almost complete. As the IS testing manager you have been assigned the task of testing the new system. Describe the four methods for interface evaluation and make a recommendation on the appropriate method or methods that would best fit the system described.
