What caused the gap between the units produced and those delivered to distributors

during the second quarter of $2020?$ How did the order fulfillment issues identified by

Steven Lee contribute $($or not$)$ to the gap observed during the second quarter of $2020?$

Hint: Answer using the concept of the bullwhip effect and identify the elements that contribute to

it in this case. Use both qualitative and quantitative approaches to explain the issues identified by

Lee and diagnose Mech Tech$$s supply chain concerns.
