Mob programming is a collaborative software development technique where the entire team works together, simultaneously, at the same computer. Developed in the early 2000s, it emphasizes refactoring code in a group setting to foster healthy discussions. A questionnaire provided insights into experiences with mob programming, highlighting its impact on software quality and team dynamics.

3. Historical Background
In early January, 2000 Hohman’s team began a series of weekly developer
lunches. The team was in a transition toward using many of XP’s suggested
lightweight practices. As part of and in order to facilitate this transition,
they developed a collaborative method called mob programming. The term
“mob programming” is whimsically derived from the term “pair program-
ming,” and indicates the practice of refactoring code in groups larger than
two developers. The purpose for this refactoring focuses less on writing
code that we will use later and more on encouraging healthy discussion.

4. Definition
Mob Programming is a software development approach where the whole
team works on the same thing, at the same time, in the same space, and at
the same computer [1]. Mob Programming, as Zuill [2] describes, is similar
to pair programming [3], where two persons work on the same computer
and collaborate on the same code at the same time. Mob also resembles
the Randori [4] style of programming popular at Coding Dojos that is used
during sessions to learn new Technologies [5].
