Question

I already find a. I need help with b

Bill's Barbershop has two barbers available to cut​ customer's hair. Both barbers provide roughly the same experience and​ skill, but one is just a little bit slower than the other. The process flow below shows that all customers go through steps B1 and B2 and then can be served at either of the two barbers at step B3. The process ends for all customers at step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer.

b. What single activity is the bottleneck for the entire​ process? B what?

The image displays a directed graph with five nodes labeled as B1, B2, B3-a, B3-b, and B4. Each node has a number indicating a certain value or weight associated with it.

- **Node B1** has an associated value of 8.
- **Node B2** follows B1 and has a value of 10.
- From B2, there are two diverging paths leading to:
  - **Node B3-a**, which has a value of 15.
  - **Node B3-b**, which has a value of 10.
- Both nodes B3-a and B3-b converge into **Node B4**, which has a value of 9.

The graph visually represents how data or processes flow through the system from B1 to B4, with two optional paths (B3-a and B3-b) that can be taken after B2. The arrows indicate the direction of the flow, showing a choice between the paths leading to B3-a or B3-b before reaching B4.
