Real World Example
te: R. R. Donnelley & Sons
Project: Convert 18,000 users dispersed across 200 facilities throughout the world from a dozen major e-mail systems into one standardized system.

Real World Example
te: London Ambulance Service
Project: After two failed attempts, develop an ambulance dispatching system capable of handling a million calls per year based on 800 vehicles, million residents, million tourists, dispersed over 640 square miles.
Results: the number of ambulances on the way within three minutes doubled; the number of ambulances on the scene within 8 minutes tripled. Lives are being saved.
Lessons Learned: encourage munications; involve the team in planning; break the project into manageable pieces.
