1. Quality By Design

2. Quality by design
▸ is the practice of using a multidisciplinary team to conduct
conceptual thinking, product design, and production planning all at
one time.
▸ It is also known as concurrent engineering, simultaneous
engineering, or parallel engineering.
▸ Team for these processes consists of specialists. Suppliers of
process equipment purchased parts, and services are also
included on the team at appropriate times.
▸ Quality by design, or concurrent engineering, requires the major
functions to be performed at the same time. However sequential
engineering the traditional method depends upon the completion
of one operation to move on to another.

4. Benefits of Implementation of Quality By Design
▸ Faster product development.
▸ Better quality.
▸ Less work in progress.
▸ Fewer engineering change orders.
▸ Increased productivity.

5. Design for Six Sigma
▸ Define the project goals and customer deliverables.
▸ Measure and determine customer needs and specifications.
▸ Analyze to generate innovative concepts, and evaluate and select
the best concept for the design.
▸ Design details, optimize the design, and plan for design
verification and validation. This phase often
▸ requires simulations.
▸ Verify and validate the design reliability and capability to meet
customer requirements
