    familiar development environment. • A room with plenty of air. • Comfortable chairs. • A large whiteboard. • A tough problem for the team to work on together. R E C O M M E N D E D M O B S E T U P

    H T L E V E L • Only got a few hours? Working with an unfamiliar team? You may want to mob program a code kata. • Already working as a team? A non-obvious, challenging task that requires the whole team to participate will show the strengths of mob programming.

    E • Ever wished you had stake holders, domain experts, UX designers, operations, customers, or end users readily available to answer questions and clarify requirements and needs? Invite them!
  11. S K I L L L E V E L

    S • Mixed teams are a strength, not a problem. • Mob programming equalises differing skill levels swiftly. • Editor key shortcuts, domain knowledge, programming language constructs and concepts, and previously stumbled- upon pitfalls are all shared.

  13. H O W T O M O B • The

    driver works at the keyboard. • The rest of the team act as navigators. • After a fixed amount of time, e.g. 10-15 min, the driver is replaced. • Repeat until everyone has acted as a driver, then repeat from the top.

    R I V E R ’ S S E AT • Once you have finished your rotation as the driver, make a note of it.

    Need a break? Take one! The important thing is that the mob continues to work. Individuals can come and go as needed.

    • Each cycle is an excellent opportunity to perform various micro-experiments. • Not used to test-driven development? Try it! • Avoid using the mouse. • Try the strong pairing style of not letting the driver write anything unless instructed to do so by a navigator.

    I V E • End the session with a short retrospective. • What worked? • What can be improved? • What would you like to do differently? • Always turn up the good!

    • Found something that works really well given your context? Perhaps learnt something unexpected about you and your team? • Write about it on your development blog. • The Twitter hashtag is #MobProgramming. • Encourage others to experiment too!
