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.

Object-Oriented analysis and design approach has become the mainstream of today¡¦s systems development technique. The Class Diagram in Unified Modeling Language (UML) is the major tool for modeling the class structure in the object-oriented system analysis and design process. Once the class diagram is constructed, class normalization needs to be performed to eliminate the anomalies for the designing a database. However, the detailed guideline for performing class normalization is lacking. Therefore, this study presents a class normalization methodology based on object normal forms proposed by Ambler (1996). Two real-world cases are presented to illustrate the concepts, application, and the advantages of using the proposed method. Using this methodology in class modeling will help system developers normalize the class design in advance, and thereby enhance the efficiency and effectiveness of system development.

Process modeling has become an essential part of many organizations for documenting, analyzing and redesigning their business operations and to support them with suitable information systems. In order to serve this purpose, it is important for process models to be well grounded in formal and precise semantics. While behavioural semantics of process models are well understood, there is a considerable gap of research into the semantic aspects of their text labels and natural language descriptions. The aim of this paper is to make this research gap more transparent. To this end, we clarify the role of textual content in process models and the challenges that are associated with the interpretation, analysis, and improvement of their natural language parts. More specifically, we discuss particular use cases of semantic process modeling to identify 25 challenges. For each challenge, we identify prior research and discuss directions for addressing them.

This thesis deals with the topic of  model-based design and application of simulation in system design. In the introduction, the thesis discusses the history of software development process and outlines the current status. The aim is to demonstrate a model-driven design on a case study of conference system. There will be presented formalisms of DEVS and OOPN  together with experimental tools PNtalk and SmallDEVS that allow to work with these formalisms. The resulting model of conference system will be deployed as part of a web application using a framework Seaside in the Squeak environment.
