Product design - ✔✔integral to the success of many companies and
differs significantly depending on the industry.
Contract manufacturer - ✔✔Companies that specialize in designing
and manufacturing products for other companies
Core competency - ✔✔The one thing that a firm can do better than
its competitors.
,The goal is to have one that yields a long-term competitive advantage to the
company.
Generic product development process - ✔✔0: Planning
1: Concept development
2: System-level design
3: Detail design
4: Testing and refinement
5: Production ramp-up
Planning - ✔✔often referred to as "phase zero" because it precedes the
project approval and launch of the actual product development process.
Begins with corporate strategy and includes assessment of
technology developments and market objectives.
,The output is the project mission statement, which specifies the target market
for the product, business goals, key assumptions, and constraints.
Concept development - ✔✔needs of the target market are identified,
alternative product concepts are generated and evaluated, and one or more
concepts are selected for further development and testing.
System level design - ✔✔includes the definition of the product architecture
and the decomposition of the product into subsystems and components.
The final assembly scheme for this is usually defined during this phase as well.
The output of this phase usually includes a geometric layout of the product, a
functional specification of each of the product's subsystems, and a
preliminary process flow diagram for the final assembly process.
, Detail design - ✔✔includes the complete specification of the geometry,
materials, and tolerances of all the unique parts in the product and the
identification of all the standard parts to be purchased from suppliers.
A process plan is established, and tooling is designed for each part to
be fabricated within the production system.
The output of this phase is the drawings or computer files describing the geometry
of each part and its production tooling, the specifications of purchased parts, and
the process plans for the fabrication and assembly of the product.
Testing and refinement - ✔✔Construction and evaluation of
multiple preproduction versions of the product.
Early prototypes are usually built with parts with the same geometry and material
properties as the production version of the product but not necessarily fabricated
with the actual processes to be used in production.
