Placewrite, Inc., an independent outplacement service, helps unemployed executives find jobs. One of the major activities of the service is preparing resumes. Three word processors work at the service typing resumes and cover letters. Together they handle about 120 individual clients. Turnaround time for typing is expected to be 24 hours. The word-processing operation begins with clients placing work in the assigned word processor's bin. When the word processor picks up the work (in batches), it is logged in using a time clock stamp, and the work is typed and printed. After the batch is completed, the word processor returns the documents to the clients' bins, logs in the time delivered, and picks up new work. A supervisor tries to balance the workload for the three word processors. Lately, many of the clients have been complaining about errors in their documents-misspellings, missing lines, wrong formatting, and so on. The supervisor has told the word processors to be more careful, but the errors still persist.
