Mobbing

A collaborative practice where several team members work together at the same time on a single work item, coordinating their efforts in real time.

Key Points

  • Whole team focuses on one item simultaneously to speed delivery and improve quality.
  • Roles often rotate (e.g., one person drives at the keyboard while others navigate), spreading knowledge.
  • Best for complex, high-risk, or ambiguous work; use timeboxes and breaks to sustain focus.
  • Reduces handoffs and rework; effective in co-located or remote sessions using shared tools.

Example

Facing a critical integration defect, the agile team schedules a 90-minute mobbing session. One developer drives at the shared screen while others propose test cases, refactoring steps, and deployment changes. The tester adds acceptance tests and the DevOps engineer updates a pipeline script. The team resolves the defect and moves the story to Done in a single session.

PMP Example Question

A cross-functional agile team is delayed by handoffs on a complex user story. The Scrum Master suggests a practice where several team members work at the same time on the single story, coordinating in real time and rotating roles. What technique is being recommended?

  1. Pair programming
  2. Swarming
  3. Mobbing
  4. Daily scrum

Correct Answer: C — Mobbing

Explanation: Mobbing is when multiple team members collaborate simultaneously on one work item, often rotating roles. Pair programming involves two people; swarming may involve many people but not necessarily working together at the same time and place on a single item; the daily scrum is a planning event, not an execution technique.
