This diagram illustrates the handoffs between Strategic Management, Business Process Reengineering, and System/Software Development as part of an overall improvement effort.
The funnel connotes that many options exist at the strategic management level, and that these options must be increasingly constrained and limited as the enterprise moves deeper into reengineering and systems development. This also illustrates the sensitivity of system development efforts to changes in the process being reengineered, and to the Mission, Vision, Goals, Performance Measures, Strategies, and Plans. A small change in a wider part of the funnel can have greatly magnified impact at the narrow end of the tunnel
