Utilize slide 11 from the lecture material and calculate:

- worktime & utilization for both Andy and Sasha

- capacity based on the assumption that Andy is working 100%.

Return your answers in an essay form along with answers to questions:

- Help Sasha and Andy figure what to improve:

How can utilization be improved?

How can cycle time be reduced?

What has to be done to serve 75 customers?

What has to be done to serve 100 customers?
