Traditional ITIL Processes

• No Test Driven Development

• Lack of verification

• No Feedback Loops

• Disjointed from other activities

• Task focused, not state focused

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

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

CLAMS

• Collaboration

• Lean

• Automation

• Measurement

• Sharing

Lean and Agile

• Operations Sprints

• Kanban

• Small Batches

• A/B Testing
