Definitions (1/3) • Product: A term used to describe all goods, services, and knowledge sold or shared.

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

Definitions (3/3) • A Design Process is the set of technical activities within a PD process that work to meet marketing and business case vision.

General Phases of PD

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 you have to use what you know. • CE relieves this difficulty.

Design Process Evolution • Craftsmanship – one person could design and manufacture an entire product • By the middle of the 20th century: over-the-wall approach. • From the late 1980s: concurrent engineering approach (CE).

Approaches to Product Development • Two fundamental approaches to product development: – Sequential /Over-the-wall approach – Concurrent/integrated approach.

Sequential approach

– Traditional way of developing products. – Divided into a number of distinct phases.

The Over-The-Wall Design Method

• Advantages of sequential approach – Easy to manage and control, since the objective of each phase is predetermined. – The process is scrutinized after each phase is finished. – Reduces uncertainty to a minimum before each phase is begun.

• Disadvantage of sequential approach – Being ill-equipped for advancing such development objectives as speed and flexibility.

• Advantage of integrated approach – Total development cycle is reduced while at the same time flexibility increases.

Concurrent/integrated approach

– Various functions overlap. – Total development cycle is reduced and flexibility is increased.

• Comparison between traditional and simultaneous development processes.

Concurrent Engineering (CE) • CE emphasizes the integration of crossfunctional TEAMS to develop the product. • The use of teams, including all the stakeholders, eliminates many of the problems with the over-the-wall method.

Controllable Variables in CE

The CE Design Team • A team may be defined as two or more persons engaged in a common goal, who are dependent on one another for results, and who have joint accountability for the outcomes. • The PRIDE principle should be followed in EXCELLEN any product development project CE DISCUSSIO PURPO RESPEC NS SE INDIVIDUA T LS

The concept of Product Life Cycle

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

Summary (2/2) • Concurrent Engineering = early involvement of stakeholders • CE suggests an integrated product and process design (IPPD) • Early phases of design are the most critical to the design success.
