  3. Concurrent Engineering • Design teams include others in addition to engineers • Manufacturing experts • Marketing and sales professionals • Reliability experts • Cost accountants • Lawyers • Concern with all these areas and their impact on the design is concurrent engineering.

  4. -ilities • Concurrent engineering demands consideration of the complete life cycle of the product, process, or project. • Design for: • Manufacturability • Affordability • Reliability • Sustainability • Quality

  5. Can this Design Be Made? (DFM) • The design of a product has an ENORMOUS impact on its manufacture. • A basic DFM methodology • Estimate the cost for a given alternative • Reduce the costs of components • Reduce the costs of assembly • Consider the effects on other objectives • If not acceptable, revise the design • REPEAT …

  6. Design for Assembly (DFA) • Limit the number of components • Using standard components • Use a base component on which other components can be located • Use components the facilitate retrieval and assembly • Maximize accessibility during manufacturing and maintenance

  7. Affordability • Engineering Economics • The time value of money • Money obtained sooner is more valuable than money obtained later. • Money spent sooner is more costly than money spent later. • Design decisions made today will translate into streams of “financial events” in the future.

  8. Arthur M. Wellington’s definition of engineering “the art of doing that well with one dollar which any bungler can do with two.”

  9. Reliability • To an engineer: the probability that an item will perform its function under stated conditions of use and maintenance for a stated measure of a variate. • Incidental failure • Catastrophic failure • Maintainability • Parts easily accessed and repaired • Redundancy

  10. Sustainability • One generation’s progress can be the next’s nightmare. • Environmental responsibility is incorporated directly into the ethical obligations of engineering. • Air and water quality • Energy consumption • Disposal • Life cycle assessment analysis • Inventory • Impact • Improvement

  11. Design for Quality • All of the –ilities are components of the design for quality • A quality design satisfies all constraints • Fully functional within the performance specifications • Meets the objectives as well or better than alternative designs • All the work of the design process is directed to design for quality.
