Product Details

Dooly County Doughnuts (DCD), a south Georgia based doughnut shop, faces capacity issues as its sales continue to grow. As its doughnuts continue to increase in popularity, DCD must gain a better understanding of its current operational capacity. The DCD case captures three key concepts: capacity analysis, batches/setup times, and Little's Law. In particular, the case works well as a first time introduction to Little's Law. This case is suitable for an undergraduate or MBA introductory operations course, and works well as exam case. The material fits particularly well in a course module on process analysis. An example sequence could include: Pancho's Burrito (OM-1555), NoBull Burger (OM-1479), Dooly County Doughnuts, Czech-Mate (OM-1390), and Stonehaven (HBS 696-048). The material could be complimented with activities such as the face game and a teaching note on process analysis (e.g., OM-1556).

1) Understand the importance of operations in supporting growth objectives; 2) Analyze operational capacities for a number of different process configurations; 3) Understand how the choice of batch size can affect capacity; and 4) Introduce students to Little's Law.
