1. Question 1
Posh Nails
Katie Posh runs an upscale nail salon. The service process includes five activities that are
conducted in the sequence described below. (The time required for each activity is shown in
parentheses):
Activity 1: Welcome a guest. (1 minute)
Activity 2: Clip and file nails. (3 minutes)
Activity 3: Paint. (5 minutes)
Activity 4: Dry. (10 minutes)
Activity 5: Check out the customer. (4 minutes)
Three servers (S1, S2, and S3) offer the services in a worker-paced line. The assignment of tasks to
servers is the following: S1 does Activity 1. S2 does Activities 2 and 3. S3 does Activities 4 and 5.
The drying process does not require server 3’s constant attention; she/he needs to only escort the
customer to the salon’s drying chair (equipped with fans for drying). The time to do this is negligible.
There exists only one drying chair in the salon.

The Gamer Company is a video game production company that specializes in educational video
games for kids. The company’s R&D department is always looking for great ideas for new games.
On average, the R&D department generates about 25 new ideas a week. To go from idea to
approved product, the idea must pass through the following stages: paper screening (a 1-page
document describing the idea and giving a rough sketch of the design), prototype development,
testing, and a focus group. At the end of each stage, successful ideas enter the next stage. All other
ideas are dropped. The following chart depicts this process, and the probability of succeeding at
each stage.
