Definition
...practice of using a multidisciplinary team to
conduct conceptual thinking, product design, and product
planning all at one time.pg. 349

Benefits
Faster product development Better quality Less work in progress Fewer engineering change orders Increased productivity Decreased time to market pg. 353
Teams
Take advantage of existing experience Emphasize early high-quality decisions Support customer requirements Feedback constraints Efficient management of risk and change as
product moves from design to sales. pg. 353
Communications Models
Organizational StructureWho talks to whoStraight line hierarchy (traditional)Cross-talk hierarchy (TQM structure/Information paths)pg. 356
Straight Line Hierarchy

Tools
TQM philosophiesComputer networksISO standards (9000 and 14000)
Total Productive Maintenance
Quality function deployment
Information Technologies (IT)
Electronic meeting software
Enterprise resource planning software
pg. 359
Production Tools
Robotics CAD/CAM/CMC Just-in-time production Virtual planning and manufacturing software Lean Manufacturing Advanced measurement and verification
pg. 356
Misconceptions and Pitfalls
Not simultaneous design and production Not a “quick fix” or “magic formula” for success Does not require multiple tests of product until
optimum design achieved. Not to replace or be confused with inspection
protocols and programs
pg. 371
Misconceptions and Pitfalls
Avoid using team members improperly Avoid promises to meet unobtainable goals or
schedules Avoid tight tolerances or stringent requirements
for one-pass design Avoid changes in product during design phase Avoid business as usual with “low-bid” vendors Avoid automation before simplification
