A new systems development project is being planned for the Reindeer Christmas Supplies Company. The invoicing, cash receipts, and accounts payable modules are all going to be updated. The controller, Kris K. Ringle, is a little anxious about this project. The last systems development project that affected his department was not very successful, and the employees in the accounting department did not accept the new system very well at first. He feels that the systems personnel did not interact sufficiently with the users of the systems in the accounting department. Prepare a memo from Ringle to the head of the information systems department, Sandy Klaus. In this memo, provide some suggestions for including the accounting personnel in the systems development project. Give some very persuasive arguments why prototyping would be helpful to the workers in the accounting department.
