Job Design Ø the act of specifying the contents and methods of jobs • what will be done in a job • Who will do the job • how the job will be done • Where the job will be done Ø Importance • Organization’s are dependent on human efforts to accomplish their goals • Many job design topics are relevant to continuous and productivity improvement Ø Objectives • Productivity • Safety • Quality of work life
Concurrent Engineering Ø the simultaneous development of project design functions Ø is a method of designing and developing engineering products in which different departments simultaneously work on the different stages of engineering product development. Ø open and interactive communication existing among all team members for the purpose of: Ä reducing time to market, Ä decreasing cost, and Ä improving quality and reliability
Design for Manufacturing and Assembly Greatest improvements related to DFMA arise from simplification of the product by reducing the number of separate parts: 1.During the operation of the product, does the part move relative to all other parts already assembled? 2.Must the part be of a different material or be isolated from other parts already assembled? 3.Must the part be separate from all other parts to allow the disassembly of the product for adjustment or maintenance?
Types of Processes • Conversion- changing iron or into steel • Fabrication- making car bumpers from plastic • Assembly- assembling a car • Testing - computer boards-not a fundamental process
Process Flow Structures • Job shop - small batches of a large number of different products. -printing, machine shop, tool & die • Batch shop - standardized job shop, products produced in batches -clothing • Assembly Line - parts move from station to station at a controlled rate -microwaves, cars • Continuous Flow - continuous versus discrete flow -beer, paint
