The electronic system in automobiles has become more important in providing
safety, comfort and entertainment, at the same time less harmful to the environment.
Due to the fact that there are varieties in automobile electronic devises, product
development has become more complex. For example, shortening product development
period while maintaining quality and fulfilling requirements of each company are all
important issues. The development of automobile electronic products cannot only
emphasize on functionality but also need to be more customer-oriented to fulfill the
needs and expectations of the users. The initial phase of product development should
focus on confirming the types of products with clients in order to develop and
manufacture into what have been expected.
The goal of product development expected by the market has obvious differences
with the actual products that have been manufactured. The reason for the differences is
the emphasis on functionality during the initial phase of product development. Also, the
development process has focused mainly on technological development instead of
customer expectations and the changes that occur during the product life cycle, which
brings in the need for “Requirements Management.” Problems such as large amount of
development cost, compensation, loss of order and reliability can be resolved through
the application of “Requirements Management.” Through observation and interviews
with management team and project managing engineers, what is lacking is the method
of demand analysis for system engineer of suppliers during the demand analysis stage to
better analyze customer needs and to combine with existing system; thus managers can
utilize the requirement analysis method to familiarize with the product. In addition,
system engineers can better distribute resources and confirm demands.
Based on the architecture-oriented model for auto electrical products, demand
analysis method can clearly integrated different aspects, including structural and
behavioral. These statistics can be utilized in the following phases during project
development, such as system design, production, testing, and proofing stages, especially
where integration with software, electrical and structural system is important and
complex for the development of auto electrical products. The architecture-oriented
model can maintain consistency and can be traceable along with the requirements
model.
