  8. 8. SCRUM didn't work
  9. 9. SCRUM didn't work Sprint planning was a challenge • Organisational - 5 teams with totally different tasks • Defining the scope with so many variables, dependancies not controlled by the teams
  10. 10. SCRUM didn't work Problems with deliverables from external vendors • Deadlines - frequent delays • Functionality - does not work or works not according to specs, or is unstable
  11. 11. SCRUM didn't work Other problems with vendors • Communication • Long time for problem resolution • Rotation of team members
  12. 12. SCRUM didn't work Problems with schedules of internal providers • Need to fit into other schedules not fully consistent with our • Fight for compromises and giving higher priority to our tasks
  13. 13. SCRUM didn't work Changing requirements from business and internal clients
  14. 14. SCRUM didn't work Lot of unexpected 'fires' which broke sprints
  15. 15. SCRUM didn't work (additional afterthought) Agile methodology means less paperwork and formalities which unfortunately works to our disadvantage with vendors
  16. 16. ...the outcome was: • Sprint plannings were long and boring for most people (the same with retrospections) • None of the sprints were finished in time and in some none of the backlogs were done • Frustration - our, in our teams and internal clients, strained relations with vendors • Deadlines not met
  17. 17. We decided to do something about it... Step 1 • We stopped Sprint planning in favour of quick planning in individual teams • Every team had individual backlog and sprint • We losened a little the sprint concept and everything related to it • We started to prioritise tasks on daily bases according to what was more urgent • We started to define new states for tasks which waited for something independent of the team
  18. 18. ...as it later turned out we were approaching ScrumBan • Breakthrough at first Agile Warsaw meeting entitled Scrum vs. Kanban • It turns out this is the tool which we need • We have noticed that we started using certain practices naturally • Pity that we discovered Kanban so late
  19. 19. SrumBan worked much better Step 2 - migration to ScrumBan • We stopped sprints and planning in favour of ad-hoc planning and estimation on daily basis • Limit to number of WIP tasks per person • Highest priority for fuckups and errors • Reorganising the teams - 3 teams: devel, telco, operations • Individual task states for each team
  20. 20. Task board - Telco
  21. 21. Task board - Devel
  22. 22. Task board - Operations
  23. 23. ScrumBan - observations • We had the pleasure of working in the new arrangement for 2 months • Decreased level of frustration with the process was evident • Increase in productivity and quality of work of the teams • Shorter time from submission to delivery of task • ScrumBan did not solve all of our problems but it did solve most of the problems associated with the process, increasing the comfort of work
  24. 24. Questions ?
