Definitions (2/3)
A Product Development Process is theentire set of activities required to bring anew product concept to a state of market
readiness. PD is the organization and management of
people and the information they developin the evolution of a product.

Definitions (3/3)
A Design Process is the set oftechnical activities within a PDprocess that work to meet marketing
and business case vision.

The Golden Triangle
Effectiveness of the design process is measured by:
2. Product cost
3. Product quality
4. Time to market (TTM)

The Design Paradox
The more you learn the less freedom youhave to use what you know.
CE relieves this difficulty.

Design Process Evolution
Craftsmanship one person coulddesign and manufacture an entireproduct
By the middle of the 20th century:over-the-wall approach.
From the late 1980s: concurrentengineering approach (CE).

Approaches to ProductDevelopment
Two fundamental approaches toproduct development:
Sequential /Over-the-wall approach Concurrent/integrated approach.
8/14/2019 1 Intro Dfma
12/27
Traditional way of developing products. Divided into a number of distinctphases.
Sequential approach

The Over-The-Wall Design
Method
8/14/2019 1 Intro Dfma
14/27
Advantages of sequential approach
Easy to manage and control, since theobjective of each phase is
predetermined.The process is scrutinized after each
phase is finished.
Reduces uncertainty to a minimumbefore each phase is begun.

Disadvantage of sequential approach
Being ill-equipped for advancing suchdevelopment objectives as speed and
flexibility.
8/14/2019 1 Intro Dfma
16/27
Advantage of integrated approach
Total development cycle is reducedwhile at the same time flexibility
increases.
8/14/2019 1 Intro Dfma
17/27
Various functions overlap.Total development cycle is reducedand flexibility is increased.

Concurrent Engineering (CE) CE emphasizes the integration of cross-functional TEAMS to develop the product.
The use of teams, including all thestakeholders, eliminates many of theproblems with the over-the-wall method.

The CE Design Team
A team may be defined as two or morepersons engaged in a common goal, whoare dependent on one another for results,
and who have joint accountability for theoutcomes.
The PRIDE principle should be followed inany product development project

Summary (1/2)
Product design is a part of theproduct development process.
PD must be centered on theCUSTOMER. The Japanese say: Listento the VOC!
Success at PD is measured by Cost,Quality, and TTM.

Summary (2/2)
Concurrent Engineering = earlyinvolvement of stakeholders
CE suggests an integrated productand process design (IPPD)
Early phases of design are the mostcritical to the design success.
