Post-implementation management of CASE methodology

Information system development methodologies and supporting CASE technology (collectively referred to as CASE methodology) are being widely used in organizations to improve the productivity and quality of the software development process. This paper reviews the implementation lifecycle of CASE methodology and suggests that the post-implementation stage is the most critical for ensuring its successful use and incorporation within an organization. Effective management of the post-implementation stage requires CASE methodology to be considered as a socio-technical innovation. The paper describes the key post-implementation processes and mechanisms for the monitoring of these processes. Finally, a field study is outlined to illustrate how these concepts have been applied to the management of a CASE methodology in a software development organization. The focus of our discussion is the framework for post-implementation management – the specific implementation guidelines for CASE methodology resulting from any such exercise are beyond the scope of this paper.     

An information processing framework for understanding success and failure of MIS development methodologies

Organizations seeking to improve systems development performance have implemented a variety of project methodologies. The success of these efforts has been mixed. Some organizations have found that implementation of a systems development methodology leads to on-time, within budget project completions with improved productivity; others have experienced reduced productivity. This paradox can be explained by viewing both systems development and the methodology development in terms of two key information processes - uncertainty reduction and equivocality resolution. Project methodologies that are implemented with the procedures, definitions, and policies necessary to reduce the uncertainty and resolve the equivocality associated with the systems development process can be successful only if the management of the process allows those mechanisms to be fully utilized. Implementation experiences with a particular methodology in different environments discussed here demonstrates that equivocality resolution during the implementation process is critical to realizing improved productivity. Suggestions for management action necessary to resolve equivocality during the implementation of a systems development methodology are discussed.     

Application of a Methodology for the Development and Validation of Reliable Process Control Software

This paper discusses the necessity of a good methodology for the development of reliable software, especialy with respect to the final software validation and testing activities. A formal specification development and validation methodology is proposed. This methodology has been applied to the development and validation of a pilot software, incorporating typical features of critical software for nuclear power plant safety protection. The main features of the approach indude the use of a formal specification language and the independent development of two sets of specifications. Analyses on the specifications consists of three-parts: validation against the functional requirements consistency and integrity of the specifications, and dual specification comparison based on a high-level symbolic execution technique. Dual design, implementation, and testing are performed. Automated tools to facilitate the validation and testing activities are developed to support the methodology. These includes the symbolic executor and test data generator/dual program monitor system. The experiences of applying the methodology to the pilot software are discussed, and the impact on the quality of the software is assessed.

An integrated product and process development methodology: Concept formulation

Life cycle engineering, or integrated product and process development (IPPD), is a new trend of research and application in industry and academia. In our previous work, a generic framework was proposed to provide a means for an integrated consideration of the performance optimization issues in a product’s lifetime. Based on this generic framework, this paper proposes and presents an integrated product and process development methodology. Important concepts of the methodology are introduced, and an application procedure is provided to illustrate the systematic application of the methodology to real product and process development. Finally, we provide a brief report of our application of the methodology to personal computer development.
