Carroll and Campbell [2] and Suchman [11] have also argued that software embodies user work processes, but stopped short of examining the profound implications for organizations and businesses. They need to respond to accelerating change in the world by improving their work processes continuously , and in some cases by reengineering them completely. Often(More)
We present the case study of a complex, mixed-initiative scheduling system to illustrate <i>Work-Centered Design</i> (WCD), a new approach for the design of information systems. WCD is based on theory of distributed cognition and extends established user-centered methods with abstract task modeling, using innovative techniques for work ontology and(More)
Our objective was to demonstrate how software methods for information systems can function as an integral part of advanced methods for re-engineering and continuously improving business processes. We report the feasibility of version 0.3 of the tools for a User-Centered Development Environment with Distributed Application Services. Our approach was to(More)
We describe our work on a User-Centered Development Environment (UCDE). UCDE is based on emerging, object-oriented software technologies, and its purpose is to investigate how software development can function as an extension of business process improvements. We focus on a method to develop business-oriented components (BOCs). BOCs are software objects that(More)
There is critical, nation-wide need to improve health care and its cost. Health information technology has great promise that is yet to be realized. In this panel four noted experts will discuss key issues that should drive health IT, and the challenges for the CHI community to play a leading role.
This paper introduces a new, model-based design method for interactive health information technology (IT) systems. This method extends workflow models with models of conceptual work products. When the health care work being modeled is substantially cognitive, tacit, and complex in nature, graphical workflow models can become too complex to be useful to(More)
