Our Original Mob Environment

Our Current Mob Environment

9. We help small businesses 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 small businesses 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 small businesses 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

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

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 small businesses 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 small businesses 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 small businesses 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 small businesses 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 small businesses succeed.
Moral Of The Story
• Collaboration is good
• When collaboration happens the solutions
pay for themselves
– Faster solutions
– Better quality
– Knowledge transfer
