- 3. Session Format • Short Intro to Mob Programming • Live remote mobbing • A little more intro and some questions • More live mobbing • Some references and more questions • Wrap up 3
- 4. Why Mob Programming? Business • Single Piece Flow – features faster to market • Features Faster to Market – faster feedback from customers • Faster Feedback from Customers – faster customer satisfaction • Faster Customer Satisfaction – happier customers – market dominance 4
- 5. Why Mob Programming? Code • Better quality code – fewer bugs – easier maintenance – faster enhancement • Why better quality? – people have ups and downs – pairing improves the ups and lowers downs – mobbing skyrockets the ups, practically eliminates downs 5 Working Alone From Mob Programming Guidebook by Maarte Pyhajarvi Mobbing
- 6. Why Mob Programming? People • Ability to break through large tasks easily • Team bonding through working together • Team members greatly improve skills • Shared ownership over decisions • Lowers risk of staff turnover • And more 6 Image from Mob Programming and Personal Satisfaction by Chris Lucian https://www.ChrisLucian.com/

- 8. Global Mob Programming Sunday’s Mob participants: 8 • Africa – Kenya • Europe – Denmark – Germany – Spain • USA – DC area – Michigan – Missouri – Utah – Washington State
- 9. “For an idea to get into the code, it has to go through some else’s hands.” – Llewellyn Falco Mobbing Roles 9 Hands Ideas Ideas Ideas Ideas Image from Mob Programming Guidebook by Maarte Pyhajarvi
- 10. Driver / Navigator Roles • Driver – Has hands on the keyboard and types – Does nothing without direction from Navigator • Navigator – Explains idea to be translated into code – Ideas flow from Navigator to Driver Level of explanation depends – Conceptual, if the Driver is more experienced – More detailed, if the Driver is less experienced 10
- 11. Other Mob Programming Roles • Other Mobbers – Those who are not the current Driver or Navigator – Ask clarifying questions – Share areas of expertise – Make suggestions, only if asked by the current Navigator in an Navigator Leads Strongly style mob – Make suggestions more freely in other style mobs – Prime Navigator always decides • Facilitator – Guides mobbing practices – Similar role to XP or Agile Coach – Doesn’t rotate with the mob 11
- 12. Mob Team Members • With Team Every Day, All Day – Always rotate between Driver and Navigator – Join as Other Mobbers when not Navigating or Driving • Occasional Mob Members – Product Owners, Business Analysts, Security, DBA, and other specialists, Managers – May be present only part of the day or rotate in and out of team 12
- 13. Remote Mobbing Rotation with Timer For Each Driver / Navigator • Practice TDD • Check in code whenever tests pass • Refactor as needed Switch on timer After Each Round • Micro Retrospective Mary Raj Tom Carlos Eva Selena (Driver) hands on keyboard 13 (Navigator) directs Driver Raj will be next Driver , Selena will be next Navigator Shared Repository
- 14. Micro Retrospective Questions • How did that feel? • What was the best thing that happened that round? – e.g. something that we want to do more of 14 “Turn Up the Good” - Woody Zuill
- 16. Test Driven Development Feedback Loop Write a test for new low level functionality Run the test and watch it fail (no code = test fails) Write just enough code to make the test pass Run the test and watch it pass Clean up complex or messy code Run test again to make sure it still passes Check in Code & Tests Check in Code & Tests 16 Red Green Refactor
- 17. Mobbing Beyond Coding • Story Mapping • Impact & Empathy Mapping • UI Design • Application Design • Database Design • Architecture • Dev Ops Pipeline • Troubleshooting 17 Top image from Jeff Patton Other images from Miro templates and examples
- 18. Two Common Questions • What about Testers, BAs, POs, SMs etc.? – If you are part of the team, you are in the Mob • Should we mob all day? – It depends on the team – Many successful teams mob continuously – Some teams mob for a number of hours daily – Some teams mob on really hard problems or to learn new things – Give mobbing a try 18 ?
- 20. Some Mob Programming Styles • Navigator Leads Strongly • Navigator Moderates and Decides • Navigator Listens and Decides • No Explicit Navigator 20
