Chapter $11$: Work System Design at Cruise International, Inc.

Details of Your Next Assignment

In this assignment you will work with Monita Terazzi, the head of the Housekeeping Services. Monita is concerned about the high turnover among Cabin Stewards$/$Stewardesses within her department. The normal scheduled work week for these crew members is $70$ hours. They are scheduled to work from $6$:$0011$:$00$ a$.$m$.$ and again from $5$:$0010$:$00$ p$.$m$.$ Currently each steward$/$stewardess is responsible for sixteen staterooms. Many of the departing stewards$/$stewardesses have complained that there is too much work to do during the scheduled hours and they often needed to work additional hours.

Monita wants you to do a work sampling to determine how the seventy scheduled hours are used each week. She has collected the following data from some preliminary observations.
