I DEAS & S OLUTIONS FOR T UTORIAL E XERCISES GSOE9810 PRODUCT AND PROCESS QUALITY IN ENGINEERING Discussion Questions Chapter 7 Question 6 Concurrent engineering refers to the practice of performing steps in the product design process simultaneously rather than sequentially. The benefits of concurrent engineering primarily include communication and speed. By working on products and processes simultaneously, fewer mistakes are made and the time to get concept to market is reduced drastically. Question 9 On page 214, the text asks: Now that we have designed it, can we make it? Another name for this situation is “as designed – as built” situation. No matter how well a product has been designed, it must able to be successfully manufactured. Operations people need to be involved in the design process. Traditionally, these departments were isolated from each other. If the communications are made simple, a better product will be produced. Question 11 Today’s complex products are generally constructed of many sub-systems. These sub- systems must operate together. For example, in a car you will have the fuel system, the transmission, the drive train and the cooling system. These systems operate interactively. A point where they do not interface well could spell failure. The “over-the-wall” syndrome occurs when the engineers who are responsible for producing the various sub-systems do not effectively communicate. Department A designs system A and then throws it “over-the-wall” for Department B to design system B. The Design For manufacture (DFM) method directly addresses this potential problem. Under DFM, there is an established procedure for multiple departments working on the same product. There is also a procedure for re-working a design that does not fit with another assembly or system optimally. Questions 16 Some months ago, the author brought his wife’s minivan into the dealership for some scheduled maintenance. While they were in the process of doing the paperwork, the auto technician pulled off a list of all maintenance that should have been performed and which items had not been done on their car. By using the vehicles Product ID Number (PIN), they were able to identify all of the maintenance that any dealership had performed on the van.
