Donner Company – Case Study Outline
1. How does Donner compete?
2. What would I see if you took me on a tour of the Donner production facilities? Let’s follow a typical 8-board panel through the process. What are the steps involved and how long will each take? [see flowchart]
3. What design decisions did Plummer make in setting up the process represented in the flowchart? What operating decisions must be made on a daily basis?
Technology choice. What are the economics of the decisions of when to use CNC router vs. punch press? Micronic vs. manual drill?
Dry film photoresist photoresist capacity capacity analysis. What is the capacity if given an order size of 8 boards? What is the bottleneck?

Capacity is not an absolute number, but is dependent on factors such as: _______________, _______________, _______________, _______________, _______________. _______________.
Labor times, as well as capacity, depend not only on the size of the order, but the mix of other products in the shop at the same time, their priorities, and on what equipment is available.
