FC method: a practical approach to improve quality and efficiency of software processes for embedded system revision

摘要

We introduce a design method for revising embedded software system. Engineers can accept requirements changes of hardware components and functions reasonably because design documents are managed in small unit. We can apply this method stepwise because this method can be coped with a development process that heavily depends on the hardware structure. We report an application of this method in our company so as to validate it. From the application, we can confirm that the quality of software was improved about in twice, and that efficiency of development process was also improved over three times.
