This chapter describes the development of a system to assist teams in determining which problems to address and what data to collect in order to incrementally improve business processes. While prototyping is commonly advocated for expert system development, this project used a structured development methodology comprising requirements analysis, knowledge acquisition, and system development. The knowledge acquisition phase resulted in a logical model, which specified the decision task and suggested a system structure. The field prototype developed from this model uses procedural cuing to guide decision makers through a decision making process. The system provides decision support, interactive training, and expert advice.
