A tire manufacturing company decided to improve the rubber extrusion process of tire products. The leadership set the primary goal of reducing wasted material in the process. The idea was to improve the rubber extrusion process, particularly in the mixing, preparation, and construction departments. To follow the DMAIC methodology, considering the information provided and the stage of affairs described, what should be your first step? Prepare a project charter to define the problem accurately Prepare a measurement plan for the possible causes Prepare a list of improvement ideas to solve the problem Prepare a detailed analysis of data on the possible causes The mixing department in a tire manufacturer receives raw materials from the supply management area and transforms them into compound sheets. These sheets are used in the preparation department on five extrusion lines that focus on the tire tread and sidewall extrusion. From the extrusion, the items move to the construction department. The company wants to improve the rubber extrusion process of tire products. In using the information to prepare a SIPOC diagram during the DMAIC Define phase, which of the following is correct? Compound sheets are outputs of the process The customer of the process is the mixing department The SIPOC customer is the construction department A supplier in the SIPOC diagram is the extrusion department
