- 9. We help smallbusinesses succeed. The Best of Times • First iteration ½ team worked as a mob • Second iteration 2 mobs • Dev & QA Combined in each mob – Write Test Cases – Code – Pair Test – Cross Mob Code Walk – Cross Mob Test in proofing
- 10. We help smallbusinesses succeed. The Worst of Times • Lost resources – Lost a developer to another team – Scheduling issues around the holidays • Collapsed to one mob – Lost black box testing ability – Same people all day every day – Lost QA interest in mob – Drivers weren’t rotating
- 11. We help smallbusinesses succeed. Bringing it to the Team • After holidays team reorg new members wanted to try mobbing • After 1st iteration they were hooked • Big team – back to 2 mobs, sometimes 3

- 13. We help smallbusinesses succeed. Why Mob Programming works? • Focus • No/Less context switching • Quiet development environment • No waiting around for someone to become available • Decision makers are in the room or available • Collaboration • Not getting stuck • Always someone to work with • Knowledge transfer

- 15. We help smallbusinesses succeed. Mob Size • <= 4 Developers feels right – Larger groups should consider splitting into multiple mobs • 1 QA per mob is ideal – Having a QA present brings quality to the forefront of development – QA is aware of what areas of the code are affected – Heightens Dev / QA collaboration
- 16. We help smallbusinesses succeed. Rotating Drivers • Tried naturally • Tried timers • Depends on task at hand – Bugs fast enough to switch at end of task – Stories we use timers and a driver order written on a white board
- 17. We help smallbusinesses succeed. Velocity • When experimenting with Mob Programming one requirement was to meet or exceed our established velocity • We found 2 mobs could meet that velocity • When collapsed we achieved the same velocity as well • This is where mobbing shines
- 18. We help smallbusinesses succeed. Personalities • The same people crammed in a room for long periods of time magnifies personality conflicts • Most developers have enjoyed this approach but we have a few that prefer other approaches • Loudest voices drown out softer ones • Without a driver policy some people rarely drive
- 19. We help smallbusinesses succeed. Smell • Several Bodies + Closed Room + Heat From Computers + Random Food = Smelly Environment • Air Fresheners • Open the door • Don’t eat in the mob room
- 20. We help smallbusinesses succeed. Moral Of The Story • Collaboration is good • When collaboration happens the solutions pay for themselves – Faster solutions – Better quality – Knowledge transfer

Editor's Notes
- #4 Mob programming is a team of developers and QA all working on the same issue at the same time, in the same place, all the time.

- #9 Meeting room with a conference table A large flat screen television with a long VGA cable Everyone brings their own computers
- #10 Goofing off in first iteration solved in retrospective Really high team morale from trying something new and having success
- #11 Despite all of this productivity still remained high Lower team morale
