Answer:
30.8 %
Explanation:
Manufacturing cycle efficiency refers to proportionate time that a product spends in value adding activities and process as compared to the entire time it is in the supply chain. The only value adding activity we can assume is when the actual manufacturing takes place thus the 4 days.
We can calculate total time by adding all the days the product was with the company such as
Total time spent in the supply chain = 4 + 4 + 3 + 2 = 13 days
so,
Manufacturing cycle efficiency = 4/13 = 0.3077 or 30.8 %
Hope that helps.
