Engineering change order – a revision to a drawing or design released by engineering to modify or correct a part concept development phase – 1st phase of a project development effort. Here a company identifies ideas for new of revised products and servicesDFM, product design for manufacturability – the systematic consideration of manufacturing issues in the design and development process, facilitating the fabrication of the products components and their assembly into the overall product serviceability, testability – serviceability the ease with which parts can be replaced, serviced, or evaluated. Testability the ease with which critical components or funtions can be tested during production pre-sourcing & pre-approving suppliers – process of preapproving suppliers for specific commodities or parts robust design, variation – design of products to be less sensitive to variations including manufacturing variation and misuse, increasing the probability that they will perform as intended.QFD, quality function deployment, roof –graphical tool used to help organizations move from vague notions of what customers want to specific engineering and operational requirements “house of quality”product development process & consumer –concept dev. Planning, design and dev, commercial preparation, launch development funnel, sequential, concurrent – a process in which the product or service idea must clear specific hurdles before it can go on to the next dev phase.design development phase – 3rd phase here the company starts to invest heavily in the development effort and builds and evaluates prototypes line balancing – technique used in developing product-based layouts, as would be found in a production line or group technology produced in large enough volumes to justify keeping a finished goods inventory. assemble to order – products that are customized only at the very end
