Problem 1:

Current Process: The flowchart shown below depicts a repetitive process. Each box represents a workstation with one worker assigned to complete each task. Therefore, there are a total of five workers for the current process.

Task 1: 3 Min --> Task 2: 2 Min --> Task 3: 4 Min --> Task 4: 6 Min --> Task 5: 3 min

Proposed Process Change 2: A second proposal would hire an additional worker to join the existing five workers. Three workers would be trained and resourced to carry out jobs made up of the current Tasks 1, 2, and 3; similarly, the other three workers would each be trained and resourced to complete the work of the current Tasks 4 and 5

1. What is the cycle time of the process ( in minutes per unit)?
2. What is the output rate (in units per hour) for the process (i.e., process capacity)?
3. What is the labor productivity (in units per labor hour) of the process?
4. What is the percent change in labor productivity between the current and the second proposed process design? ( the labor productivity for the current process is 2 labor units per labor hour)
