38. Traditional ITIL Processes
• No Test Driven Development
• Lack of verification
• No Feedback Loops
• Disjointed from other activities
• Task focused, not state focused

41. A Better Way Forward
• Testing and verification at each step
• Feedback loops built in
– Success/Fail
– Code Review
• Changes automatically flow into lower
environments
• Focuses on maintaining the state, not tasks

42. A Better Way Forward
• Leverages the Software Development Lifecycle
• Eases the compliance burden
• Process built in, not bolted on
• Achieves the goal on ITIL without the overhead

43. CLAMS
• Collaboration
• Lean
• Automation
• Measurement
• Sharing

44. Lean and Agile
• Operations Sprints
• Kanban
• Small Batches
• A/B Testing
