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

Copyright ©2017. All Rights Reserved

1st Way – System Thinking1. 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 constraints1. Environment creation2. Code deployment3. Test setup and run

6. Eliminate Waste in the value stream1. Partially Not Done work2. Extra processes3. Extra features4. Manual work

2nd Way – Amplify the feedback loops

2nd Way – Amplify the feedback loops1. 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
