Concurrent engineering is a strategy where all tasks involved in product development are done simultaneously through collaboration between individuals, groups, and departments. It involves customer research, design, marketing, accounting, and engineering working together. The key aspects are communication through formed teams and management support. The benefits are reducing time to market by 25% or more, lowering capital investment by 20% or more, and increasing product life cycle profitability.

Why Concurrent Engineering?
 Pace of market change has increased
 Companies must keep pace with changing
markets
 Decisions made sooner rather than later
 Reduces/eliminates repetition of tasks
 Reduces waste and reworking of design
 Product quicker to market
 Maximises company profit
 Company operates more efficiently

Case study 1: Desktop computer
Design Stage:
•The design could specify the following
•Reusable components e.g. monitor, keyboard
•Recycled materials where possible
•Minimise toxic materials used
Manufacture:
•Use ethical work practices and sources for raw materials
•Use ‘clean’ manufacturing processes
•Minimise transport of components and materials
•Implement quality procedures to minimise waste etc.
Use:
•Low power consumption
•Serviceable items rather than replaceable e.g. disk drive, peripherals etc.
Disposal:
•Design for disassembly – use easily dismantled fixings etc.
•Identify materials used for recycling
•Minimise mixed materials to facilitate separation later

Example:
A washing machine to last for ten years in normal use.
Expected typical household use: three times a week for a wash
cycle that will last for 2 hours on average.
What type of test should be used?
How long must the machine survive during the test?
Total hours life required for the machine is:
2 hours/wash x 3 washes/week x 52 weeks/year x 10 years = 3120
hours
Use a quantitative accelerated test. Run the machine constantly for
3120 hours

15. Concurrent Engineering
Benefits
Reduces time from design concept by 25% or
more.
Reduces Capital investment by 20% or more.
Continuous improvement of product quality.
Increases Product Life Cycle Profitability.

16. Concurrent Engineering
Summary
Concurrent Engineering: Simultaneous
development of product and process.
Most important aspect is communication and
formation of teams.
Management support is vitally important.
Don’t be afraid to change current processes and
technologies.
