Since the Software Engineering Institute published the Capability Maturity Method Integration (CMMI) in 2003, many software firms have implemented it to enhance its software quality assurance and international collaboration. Analysis and design phases are two important phases for the software development. The artifacts of these two phases mainly represented using the structured technique or the object-oriented technique. This study proposed a methodology which provides guidelines to compare the artifacts of these two techniques for an embedded system. The research methodology is articulated using the design science research methodology. A usability valuation with a real-world embedded system case is performed to demonstrate its applicability. The results provide evidences to enhance our understanding about the strength and weakness of these two nalysis and design techniques.

Structured technique is the traditional and the popular systems analysis and design language. With the rapid progress and development of information technology, embedded systems have penetrated into most of the equipments which we used daily. Over the past few years a considerable effort has been made in modeling the platform independent model (PIM) for business information systems. However, the detailed guideline for modeling the PIM of embedded systems is lacking. This study proposed a PIM modeling methodology with structured technique for embedded systems. The structured modeling process is consisted of three parts: requirement modeling, process modeling and module modeling. For each part, its modeling tool, modeling processes and rules are provided. The research methodology is articulated using the design science research methodology. A usability evaluation is performed to demonstrate its applicability with a real-world embedded system case. The evaluation results indicated that with this proposed method, the system developer can easily and effectively analyze and design the embedded systems with structured technique.
