What Is Swarming?
Swarming is a method in which multiple team members focus collectively on resolving a specific problem or completing a single work item, rather than each working on separate items in parallel.
In Practice
When a high-priority item is blocked or at risk, the team temporarily converges on it — pairing, sharing knowledge and clearing obstacles together — until it is done. Swarming reduces work in progress, shortens cycle time for critical items and spreads knowledge across the team. It is especially useful for urgent defects or items nearing a deadline.
PMBOK 8 Context
Swarming reflects the collaborative, team-centered mindset of the Team and Delivery performance domains in the PMBOK Guide, 8th Edition. It is closely related to self-organizing teams and pairing practices.
FAQ
How is swarming different from mobbing? Mob programming has the whole team work on one item continuously as a default; swarming is a targeted, temporary response to a specific item.
Does swarming hurt productivity? Short term it concentrates effort, but by finishing critical items faster and limiting work in progress it usually improves overall flow.
