For the company assigned by your instructor, prepare a control matrix for the purchasing and/or the receiving functions only, as appropriate for the case in question. Observe the following specific instructions:
a. Your choice of recommended control plans should come from this chapter plus any other control plans from Chapters 9 through 11 that are germane to your company's process.
b. Annotate the systems flowchart (either prepared by you in P12-2 or distributed by your instructor) to show the points where control plans are "present" (codes P-1 . . . P-n) or where they are "missing" (codes M-1 . . . M-n).
c. Because your explanations of the cell entries are as important as the cell entries themselves, pay particular attention to step 5 in "Steps in Preparing a Control Matrix," Exhibit 9.1 (page 287).
d. In the appropriate control goal columns of the matrix, (1) identify the specific resources of this process, for which we want to ensure security of resources, and (2) indicate the master data, for which we want to ensure update accuracy (UA) and update completeness (UC).
