Is Concurrent engineering is the name of the
game?
Although the waterfall model is a useful tool for introducing
design controls, its usefulness in practice is limited. The model does
apply to the development of some simpler devices. However, for more
complex structures or devices, a concurrent engineering model is more
representative of the design processes in use in the industry and is key
to success in any industry, where design and manufacturing come together
“and stay together” from concept to finished parts, systems, and
vehicles, reporting from both the manufacturing and engineering
perspectives. In a traditional waterfall development scenario, the
engineering department completes the product design and formally
transfers the design to production. Subsequently, other departments or
organizations develop processes to manufacture and service the product.
Historically, there has frequently been a divergence between the intent
of the designer and the reality of the factory floor, resulting in such
undesirable outcomes as low manufacturing yields, rework or redesign of
the product, or unexpectedly high cost to service the product. One benefit of concurrent engineering is the involvement of
production and service personnel throughout the design process, assuring
the mutual optimization of the characteristics of a device and its
related processes. While the primary motivations of concurrent
engineering are shorter development time and reduced production cost,
the practical result is often improved product quality.
The objective is to eliminate multiple design
revisions, prototypes, and re-engineering efforts and create an
environment for designing right the first time. The major
perceived disadvantage of concurrent engineering is that it increases
the time spent in preliminary design, when the design staff is anxious
to finalize details and release drawings. Design for manufacturability
is the process of proactively designing products to optimize all the
manufacturing functions: fabrication, assembly, test, procurement,
shipping, delivery, service, and repair, and assure the best cost,
quality, reliability, regulatory compliance, safety, time-to-market, and
customer satisfaction. An unbalanced view leaning too far towards
Concurrent Engineering will produce a surfeit of activities involving
teams, quality circles; ISO 9001, process modeling, QFD, and the DFX
acronyms (Design for Manufacture), Assembly, Decommissioning, etc. Concurrent Engineering is a long-term
strategy, and it should be considered only by organizations willing to
make up front investments and then wait several years for long-term
benefits. Definition Concurrent engineering is a business strategy
which replaces the traditional product development process with one in
which tasks are done in parallel and there is an early consideration for
every aspect of a product's development process. Strategic Plan of
Concurrent Engineering recognized as a strategic weapon that businesses
must use for effective and efficient product development.
Concurrent engineering encompasses a range of practices
and techniques. From a design control standpoint, it is sufficient to
note that concurrent engineering may blur the line between development
and production. On the one hand, the concurrent engineering model
properly emphasizes that the development of production processes is a
design rather than a manufacturing activity. On the other hand, various
components of a design may enter production before the design as a whole
has been approved. Thus, concurrent engineering and other more complex
models of development usually require a comprehensive matrix of reviews
and approvals to ensure that each component and process design is
validated prior to entering production, and the product as a whole is
validated prior to design release.
Concurrent engineering is only a set of
process objectives and goals that have a variety of implementation
strategies. Definition Concurrent engineering is a business
strategy which replaces the traditional product development process with
one in which tasks are done in parallel and there is an early
consideration for every aspect of a product's development process.
The Concurrent Engineering Approach is a business strategy which
replaces the traditional product development process with one in which
tasks are done in parallel and there is an early consideration for every
aspect of a product's development process.
The process must be updated and revised on a
regular basis to optimize the effectiveness and benefits in the
concurrent engineering development process. Increased Performance
Companies recognize that concurrent engineering is a key factor in
improving the quality, development cycle, production cost, and delivery
time of their products. For example, if manufacturing representatives
are present early in the development cycle, the design can reflect
fabrication requirements and cost can be reduced. The service uses concurrent engineering
methods to bring together marketing, product design, manufacturing and
business expertise to support the successful design and innovation of
products and processes, is a philosophical approach to the way
engineering should be carried out and is theoretically defined as a
systematic approach to the concurrent design of products and their
related processes, including manufacture and support. The key to
such an approach appears to lie in whether employees see it as
manipulation or as an honest desire to communicate and understand their
viewpoint. Concurrent Engineering is the relatively
recent term applied to the engineering design philosophy of
cross-functional cooperation in order to create products which are
better, cheaper, and more quickly brought to market. Concurrent engineering is the name of the
game. |
