Workflow structuring and reengineering method for design process

A short lead time for product commercialization is a critical advantage in the era of highly challenging competitions. It is more difficult, however, to shorten the design process rather than manufacturing process since the underlying design activities in process and related data are often interlinked and quite uncertain, and the attempts to perform the design activities concurrently increase the complexity of the design process.

In case the targeting process is well-structured and easy to be managed, many approaches have been proposed and it is the best way to use the well-known reengineering method such as crashing the bottle-neck activity. However, they have only concerned mainly about well-defined procedures, not an operational-level sophisticated workflow.

As a means to effectively manage and accelerate the design process, a process or workflow model needs to define complex relations such as iteration or coupled dependency in design process in order to coordinate the sophisticated process effectively. And, the acceleration approaches based on the operational-level information needs to be discussed.

Firstly, in order to develop an appropriate model that effectively captures the operational-level characteristics in design process, we define the workflow including the control and data flow with an incidence matrix called Workflow Matrix (WfM). Secondly, a workflow structuring method is developed for identifying the reengineering issue and it also transform the complex design process into a well-structured workflow. Finally, we analyze the design process with WfM and suggest reengineering strategies to improve the design process.

A methodology and tool environment for process analysis and reengineering

Most private and public organizations have recently turned their attention to the process by which they operate, to improve service and product quality and customer satisfaction. To support business process reengineering, methods and tools for process modeling and analysis are required. The paper presents the ARTEMIS methodology and associated tool environment for business process analysis for reengineering. In the ARTEMIS methodological framework, business processes are modeled as workflows and are analyzed according to an organizational structure perspective and an operational structure perspective. With these two perspectives, the analyst can plan reengineering interventions based on the degree of autonomy/dependency of organization units in terms of coupling, and the inter-process semantic correspondences, in terms of data and operation similarity, respectively. The ARTEMIS methodology and associated tool environment have been conceived and applied in the framework of the PROGRESS research project. In the paper, we report on a reengineering case study of this project involving the Italian Ministry of Justice.     

Representing Navy tactical computer system knowledge for reengineering and integration

This article describes an ongoing project in representing knowledge about Navy tactical computer systems. The primary concern is for their continuing evolution and/or integration with other tactical systems. Following an introduction to this class of application and a review of how the Naval Surface Warfare Center is addressing the issue of extending the investment in these systems, the software process is examined and two alternative, incompatible paradigms are presented. The latter, which relies on the use of software knowledge, is described briefly, and an environment that implements this paradigm is presented as a proof of concept. Because the transfer of this paradigm to the desired Navy applications will not be completed in the near future, the article concludes with the presentation of a general framework for classifying Navy reengineering projects that should improve assessment and also aid in the building of a knowledge base to support the improved process model.Mr. Blum's work was supported in part by the U.S. Navy, Space and Naval Warfare Systems Command (SPAWAR) under contract N00039-89-C-0001, task VMAR9 with the Office of Naval Research (ONR) and the Naval Surface Warfare Center (NAVSWC).Ms. Moore's current affiliation is with the Defense Information Systems Agency, Arlington, VA 22204-2199.
