Design for Quality:

Product Excellence

Steps in Product Development

1. Idea Generation: Develop concept incorporating customer

needs and expectations.

2. Preliminary Concept Development: Study new ideas for

feasibility.

3. Product/Process Development: Evaluate design alternatives

and determining engineering specifications; test prototypes;

develop, test, and standardize processes.

4. Full-Scale Production: Release the product to manufacturing

or service delivery teams.

5. Market Introduction: Distribute to customers.

6. Market Evaluation: Market evaluation and customer

feedback to initiate continuous improvements.

Concurrent Engineering





Concurrent engineering is a process in which all major

Multifunctional teams, usually consisting of 4 to 20

members and including every specialty in the company.

The functions of such teams are to perform and coordinate

the activities in the product development process

simultaneously, rather than sequentially.

Concept Development and

Innovation





Concept development is the process of applying

scientific, engineering, and business knowledge to

produce a basic functional design that meets both

customer needs and manufacturing or service delivery

requirements.

Innovation involves the adoption of an idea, process,

technology, product, or business model that is either

new or new to its proposed...
