Enhancing the ESIM (Embedded Systems Improving Method) by Combining Information Flow Diagram with Analysis Matrix for Efficient Analysis of Unexpected Obstacles in Embedded Software

In order to improve the quality of embedded software, this paper proposes an enhancement to the ESIM (Embedded Systems Improving Method) by combining an IFD (Information Flow Diagram) with an Analysis Matrix to analyze unexpected obstacles in the software. These obstacles are difficult to predict in the software specification. Recently, embedded systems have become larger and more complicated. Theoretically therefore, the development cycle of these systems should be longer. On the contrary, in practice the cycle has been shortened. This trend in industry has resulted in the oversight of unexpected obstacles, and consequently affected the quality of embedded software. In order to prevent the oversight of unexpected obstacles, we have already proposed two methods for requirements analysis: the ESIM using an Analysis Matrix and a method that uses an IFD. In order to improve the efficiency of unexpected obstacle analysis at reasonable cost, we now enhance the ESIM by combining an IFD with an Analysis Matrix. The enhancement is studied from the following three viewpoints. First, a conceptual model comprising both the Analysis Matrix and IFD is defined. Then, a requirements analysis procedure is proposed, that uses both the Analysis Matrix and IFD, and assigns each specific role to either an expert or non-expert engineer. Finally, to confirm the effectiveness of this enhancement, we carry out a description experiment using an IFD.14th Asia-Pacific Software Engineering Conference (APSEC\u2707), 4-7 Dec. 2007, Aichi, Japa

An analysis method with failure scenario matrix for specifying unexpected obstacles in embedded systems

This paper describes an analysis method with failure scenario matrix for specifying unexpected obstacles in order to improve the quality of embedded systems. Although embedded software has become increasingly large in scale and complexity, companies are requiring the software to be developed within shorter periods of time. Therefore, the quality of the software is bound to suffer. This problem is one of the most serious concerns in a coming age of ubiquitous embedded systems. In order to improve the quality, it is very important to specify the forbidden behavior of embedded systems. The forbidden behavior of unexpected obstacles is analyzed by using a matrix and scenarios. This paper provides a detailed description of the analysis method used, in particular the cause, phenomenon, and goal in the scenario, relating them to each other by using a matrix.Proceedings of the 12th Asia-Pacific Software Engineering Conference, December 15-17, 2005, The Grand Hotel in Taiwa
