Since the Software Engineering Institute (SEI) published the Capability Maturity Method Integration (CMMI) in 2003, many software firms have implemented it to enhance the software quality assurance and international collaboration. The CMMI is now considered to be the price for entry to run a software business. However, implementing the CMMI is complex and necessitates an implementation methodology. In Taiwan, most of the software firms implement the CMMI with the help from the consultants. It is expensive especially for a small and midsize firm. Therefore, the purpose of this study is to develop a feasible CMMI ML 2 implementation methodology based on two cases that have successfully implemented the CMMI ML 2. This study utilizes the systems development research method to investigate the CMMI ML 2 implementation methodology including, the implementation procedure, the stakeholders and the needed training and the needed documentations for each implementation phase. Finally, a case study is used to validate our results. With this methodology, the small and midsize firms can more easily and systematically implement the CMMI ML2, thereby reducing the cost and risk in implementing CMMI.

Our modern information society has produced many sophisticated requirements for the development of information systems. A new challenge is the study of hybrid information systems that combine traditional information systems with knowledge-based systems. This new generation information system is considerably more powerful than a simple extrapolation of existing system concepts. It is easy to imagine the advantages of powerful knowledge-based systems with efficient access to several large databases, and of large traditional information systems with added intelligence. Due to the complex nature of hybrid information systems, it is umealistic to expect that they can be developed using one standard method. The use of several independently developed methods has a number of drawbacks, such as inconsistency, redundancy, amount of effort required and possible loss of information. In an attempt to provide at least a partial solution to this problem. this thesis describes a new integrated methodology for developing hybrid information systems. This methodology combines the method for developing traditional information systems with the method for developing knowledge-based systems. The new methodology provides a hybrid lifecycle process model to combine the conventional waterfall process with rapid prototyping and model-based approaches. The proposed methodology integrates four eXlstmg methods using two integration approaches: intra-process and inter-process. In the requirements analysis phase. a structured method is applied to function analysis, an information modelling method is applied to data analysis, and a knowledge acquisition method is applied to knowledge analysis. An intraprocess approach is then used to integrate these techniques using consistency rules. In the design phase. the new methodology uses an inter-process approach to transform requirements analysis to object-oriented design by a transformation algorithm. Finally, an object-oriented method is applied to the design and implementation of hybrid information systems. Using the new methodology, a hybrid medical information system for dizziness (HMISD) was developed, which combines components of traditional medical information systems with components of medical expert systems. The construction and development of this software are described in detail. The system can support activities in hospitals including registration, diagnosis, investigations, drug management and clinical research. It provides assistance to hospital doctors and general practitioners. The performance of HMISD is evaluated by testing ninety three real patient cases and taking two investigations from medical staff and patients. The evaluation results show that HMISD is of good quality and that most of its users are satisfied. Three approaches are used to evaluate the proposed methodology: analysis of the development of HMISD, comparison with existing methodologies using CMD and expert evaluations. The evaluation conclusions indicate that this new integrated methodology can take advantage of the four existing methods and also remove some of the limitations of each individual method. It is applicable to the development of traditional information systems, knowledge-based systems, and large and complex hybrid information systems.

The introduction of the functional safety standard ISO 26262 was motivated by an increasing demand to ensure reliability and correctness of safety-critical systems in the automotive industry. However, the adoption of this standard in the automotive industry is hindered by a number of obstacles. Scania is an industrial partner in the VeriSpec project which studies these obstacles and proposes relevant tools and methods compliant with academic and industrial needs. This thesis is within the scope of the VeriSpec project, and aims to address one of the project’s goals, which is to provide tool support for a pattern-based requirement formalization process. The Specification Property System (SPS) proposed by Konrad and Cheng is a patterning method that provides automatic translation of system properties into temporal logics. The SPS also helps in restricting the introduction of ambiguities and inconsistencies in system specification properties. However, the adoption of the SPS in the industry is hindered due to some issues. These issues are, a long learning curve, Constrained Natural Language (CNL) ambiguities, and the lack of tool-support for real-time SPS patterns. In this thesis, a qualitative research study with a literature survey has been performed to find and select state-of-the-art supportive methods to provide feedback on the formalized requirements’ semantics. The Scania Specifier tool has been extended and modified to support a requirement formalization process using the SPS qualitative and real-time patterns. In addition, three supportive methods that resulted from the research study have been integrated into the Specifier tool to provide different feedback options for the users. Finally, the performance of the Specifier tool and the feedback of the supportive methods have been evaluated. The outcome of the study shows that the feedback of the supportive methods helped in guaranteeing the intended behavior of the requirement developers. In addition supportive methods’ feedback enhanced user-friendliness, and aided the users in shortening the SPS learning curve. Finally, an additional outcome of the study is in the form of a number of suggestions and emerged patterns with regard to the SPS usage and supportive methods’ feedback.

The purpose of this article is twofold, first to promote the use of patterns in the analysis phase of the software life-cycle by proposing an outline template for analysis patterns that strongly supports the whole analysis process from the requirements analysis to the analysis model and further on to its transformation into a flexible design. Second we present, as an example, a family of analysis patterns that deal with a series of pressing problems in cooperative work, collaborative information filtering and sharing, and knowledge management. We present the step-by-step evolution of the analysis pattern virtual library with active agents starting with a simple pinboard. In this paper we propose that using patterns in the analysis phase has the potential to reducing development time by introducing reuse already at the analysis stage and by improving the interface between analysis and design phase. To quantify our proposal we present results from the Virtual University project of the Vienna University of Economics and Business Administration, where the analysis patterns developed in this paper were used to implement several information systems.

Even though Scrum is nowadays widely known in the Software Industry field and its theoretical frame extensively described in the literature, its implementation is far from being straightforward. As a matter of fact, the literature describes a meta-process that new practitioners must adapt to their project specific constraints. However, this practical aspect is crucial and very scarcely tackled. To that extend, this thesis work describes the difficulties we faced while putting Scrum into practice and how, through the study of the project contextual factors, the insight of a Proof Of Concept and the support of a couple of agile practices, we worked it out.
