Where do ideas for systems development projects come from? Problems, and suggested solutions to problems that bubble up through the organization. Strategic analysis of the organization and its business situation. Serendipity -- bright ideas out of nowhere, or accidents that spark ideas about great opportunities.

Three Ways to Bring IT to Bear on the Business Process automation problem analysis vs. root cause analysis Process improvement duration analysis, activity based costing, benchmarking Business Process Reengineering outcome analysis; breaking assumptions, technology anal. Activity elimination; Proxy benchmarking, process simplification For each: As-Is models?; improvements; To-be models
Five primary concepts that make up reengineering (Davenport) A “clean sheet of paper” approach to org design and change An orientation to broad, cross-functional business processes, or how work is done. The need for, or possibility of radical change in process improvement Information technology as an enabler of change in process performance Changes in organizational and human arrangements that accompany change in technology.

Davenports Lessons: Implementation is harder than Design. Big Risks of Failure Clean sheet of paper is expensive. Top down hits rocks when it changes the way people do their work. The big lesson is still that we must focus on improving our business processes Information Technology is only useful if it helps people do their work better (and perhaps differently)
Stoddard and Jarvenpaa’s comments: Distinguish between Design and Implementation. Design must be radical (to be reengineering) Radical Implementation is tough unless: self contained units an acknowledged crisis, battle for survival deep pockets [excellent project management skills ability to borrow from outside willingness to use revolutionary path] Incremental Implementation translate it into a series of operation crises make it pay its way fit into an organization culture of continuous improvement
