Key Benefits of QFD

Quality Allows organization and leveling of requirements Helps optimize product and process designs

Cost Streamlines requirements iteration process Reduces number of engineering changes

Shortens product development cycle

Communication Emphasizes the Voice of the Customer Provides common language and data base

Promotes understanding of multi-discipline requirements

Documentation Provides continuous, comprehensive evaluations and sensitivities

Produces a detailed/living documentation trail

When Is QFD Helpful

Multiple customers or users

Conflicting customer priorities Multiple disciplines involved

User requirements not quantifiable

Everyday p roblems!

Multiple feasible solutions

Solutions conflict with each other Solution not yet quantified

Decision Analysis Using QFD

Articulate and define problems - WHAT specifics are desired?

Determine relative importance of each to the owner

Survey the range of solutions - HOW are specifics achieved?

Access value/importance of solutions Decompose solutions into next set of WHATs and HOWs

Each assessment and decis ion

is documented.

A l l steps are easi ly traced

QFD is a structured, matr ix-based process for

exploring solutions to complex problems

a Sequence of Steps

0 Identify scope, constraints, and groundrules

1 Identify the customer requirements (WHATs)

2 Prioritize customer requirements

3 Identify the competing solutions (HOWs)

4 Relate HOWs to WHATs

5 Correlate the competing solutions (HOWs)
