The document discusses how Lean principles can be applied to continually improve IT service delivery. It provides three examples:
1) A government agency used Lean tools like failure mode analysis to standardize support patterns and improve incident response times.
2) A bank used value stream mapping and metrics to identify weak links causing outages and reduce customer retention risks.
3) A gaming company insourced their service desk after finding outsourcing introduced waste and higher support costs. Lean helped reduce waste and costs while improving service.
