- Heizer and Render advises that when analyzing and designing processes to transform resources into goods, the followingquestions should be asked:- Is the process designed to achieve competitive advantage in terms of differentiation, response or low cost?- Does the process eliminate steps that do not add value?- Does the process maximize customer value as perceived by the customer?- Will the process win orders?A Time-Function Map is similar to a flow process chart, but with time added to the horizontal axis. With time-function mapping,notes indicate the activities and arrows indicate the flow direction, with time on the horizontal axis.Heizer and Render advises that when analyzing and designing processes to transform resources into goods, the followingquestions should be asked:- Is the process designed to achieve competitive advantage in terms of differentiation, response or low cost?- Does the process eliminate steps that do not add value?- Does the process maximize customer value as perceived by the customer?- Will the process win orders?A Time-Function Map is similar to a flow process chart, but with time added to the horizontal axis. With time-function mapping,notes indicate the activities and arrows indicate the flow direction, with time on the horizontal axis. 1. Choose a process within your organization and construct a Baseline Time-Function MapA startup company is considering making a part by injection molding. The part is moderately complex and the volume of the part is about 10 cubic centimeters. Assume that the part is designed for injection molding and can be made with a two part mold. The company needs to make 250,000 parts made from ABS plastic. Once the mold is made it will take a worker 1 minute to make one part using the injection molding machine. The company will use contract manufacturing to produce the parts. Estimate the cost per part and explain how you came up with the number. (If you are stuck look at the Contract Manufacturing Cost per Unit section. Also keep in mind that there is no exact right answer, the goal is to come up with a reasonable estimate.) Contract Manufacturing Cost per Unit: It’s not uncommon to hire another company to perform some or all the manufacturing for a product. To estimate the cost use ((Cost of Parts and Materials) + (man hours) × $40)/.75
