At CanGo the workloads are likely to vary among the different days of the week. Debbie has determined the historical pattern for demand and has described the data in a Demand Memo to Warren.
Let's see how well you answered the questions.
| 1. |

The key to this problem is to allocate the overall hours for the week (400) to each day to determine how many hours are required each day. Then divide by 8 hours per worker to give the desired number of workers. The following table details the calculations.

After reviewing Debbie's information, Warren notes that there are problems in simply translating orders into workers. For example, as Debbie mentions in the video, CanGo now operates with a skeleton crew on the weekends because the courier trucks don't operate then. Take a look at Warren's Memo.
Make the necessary adjustments in the workload requirements in the memo and then recalculate the number of workers needed each day. |

In the video, Warren also mentions a heuristic for scheduling workers to make sure that they have off two days a week. Read the Heuristic Memo that Warren describes in a memo to Debbie. Debbie has prepared a table of the first shift employees along with the worker requirements for each day using the original daily requirements.
Use the heuristic to schedule workdays and days off for this shift. There is a problem with this Scheduling Heuristic. Can you figure out what it is? |

The following table gives the solution to this problem. The most obvious difficulty with this schedule is that only two workers (Edna and Zack) have consecutive days off. Since most employees desire consecutive days off, this may cause some grumbling from the workers.
