4. And the frustration continued…

1. Chaos at production because of frequent deliveries
2. Lot of manual work resulting in deployment issues and downtime
3. Still works in silos, no end-to-end ownership
4. Lead time between development completion to customer delivery

1st Way – System Thinking
http://itrevolution.com/wp-content/uploads/2012/08/first-way2.png
Understand and increase the flow of work, from left to right

1st Way – System Thinking
1. Make work visible – Kanban or Sprint board
2. Limit WIP – context switching and multitasking
3. Reduce the batch size – annual vs monthly release schedule
4. Reduce the number of handoffs – horizontal and vertical both
5. Continually identify and elevate our constraints
1. Environment creation
2. Code deployment
3. Test setup and run
6. Eliminate Waste in the value stream
1. Partially Not Done work
2. Extra processes
3. Extra features
4. Manual work

2nd Way – Amplify the feedback loops
Create short feedback loop that enables continuous improvement, right to left

2nd Way – Amplify the feedback loops
1. See problems as they occur – GM car manufacturing
2. Swarm and solve problems to build new knowledge – Andon cord
3. Keep pushing quality closer to the source – testing, approvals, deployments etc.
4. Enable optimizing for downstream work centres – internal customers

3rd Way – Continuous Experimentation and Learning

3rd Way – Continuous Experimentation and Learning
1. Enabling organizational learning and a safety culture
2. Institutionalize the improvement of daily work – Technical debt, Alcoa case study
3. Transform local discoveries into global improvements – reinventing the wheel
4. Inject resilience patterns into our daily work - RBS
