create a DMAIC approach to this coffee shop case study

Fever Beverages is a typical coffee shop which operates at Batangas. Recently, the general manager is facing a challenge about not meeting their target lead time of serving the hot coffee of 15 minutes. The lead time starts from order taking until order serving. The staffing model of the shop has one cashier, one barista and a guard. The number of staff, equipment and raw materials has been found sufficient. Based on initial data analysis, the volume of customers has been stable. Because there is a need for the lead time to improve as to retain its customers and to even grow, a problem solving effort has been started using the Lean Six Sigma DMAIC approach.
