DMAIC Project INE-3600

Autumn 2020

Individual report delivery October 12th 2020 at 8.00 AM

Case description

You already know the hot dog stand of Sasha and Andy from exercise 1.

Sasha and Andy has decided to improve their business by doing an improvement project, and you are

now hired as consultants for the improvement project. The problem they are facing is the growing

demand for their product during opening hours and especially around lunchtime.

At the same time they have to think about the quality of their product. Every day they have to throw

away hot dogs because the skin has “cracked” during cooking.

Critical questions given by Sasha and Andy are for instance:

? 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?

your set up.
