The pugh method3 l.jpg
The Pugh Method

  • Problem definition

    • Identify design criteria

    • Customer’s voice in process

    • Quality Function Deployment (QFD) process


The pugh method4 l.jpg
The Pugh Method

  • Goals:

    • Overcome negative features or shortcomings of design

    • Find different ideas to satisfy criteria

    • Exploring alternatives

The Pugh Method

  • Economic advantages

    • Reduce cost in design process

    • Limit change later by better design

    • Invest effort early, benefits later


Ten cash drains in product development l.jpg

Technology push/where pull?

Disregarding voice of customer

Eureka concept

Pretend designs

Pampered product

Hardware swamps

Here’s product / where’s factory

“Always made it this way”

Need for inspection

Give me targets; get out of my way

Ten Cash Drains in Product Development


Pugh method l.jpg
Pugh Method

  • Process, phase one

    • Criteria: develop list of evaluation criteria

    • Design concepts: original design concepts brainstormed

    • Evaluation matrix: each design evaluated against datum, add new concepts

    • Analysis of each round, adjustments and establish new datum, repeat

  • Process, phase two

    • Better design: weak designs dropped, continue process, designs developed in more depth/detail, criteria refined

    • Superior concept: process converges on a strong consensus. Team committed

Pugh Method

  • Criteria

  • Conceptual design

  • Evaluation matrix and process

  • Evaluation of first round results

  • Fewer but better designs

  • Convergence to superior design
