  124. 124. Lessons from Service Desk● Variation of personal kanban  Sticky notes at the side of the keyboard  One priority at once  Need business reason to change priorities  Record reason and number of times you had to revisit the task©LeanAgileMachineCreative Commons Licence
  125. 125. DevOps overload● Lots of last minute ● DevOps have no time to patches script deployments ● Have to deal with long,● Deployment like boring deployment buses, nothing for a documents few days then three ● Repeatedly swiched from come at once for the infrastructure work, same night vastly increasing time taken.©LeanAgileMachineCreative Commons Licence
  126. 126. Summary of Kanban● Visualse work● Manage WIP ● Helps you stay sane● Engage with business ● Show you are  Shared ownership productive● Encourage realistic ● Deal with micro- priorities management©LeanAgileMachineCreative Commons Licence
