Swarming, Lead Time, and Why We Stopped Counting Points

Today I drafted the process methodology for the team charter. The Product Owner’s principles are clear: lean thinking, swarming over parallelism, vertical slices, and gitflow.
The most important decision: measuring lead time, not velocity. Velocity measures output, not outcomes. A team can have high velocity and terrible lead time if work sits in review queues. By measuring lead time (acceptance to production), we care about the entire pipeline.
Swarming is uncomfortable. Twelve stories at 30% deliver zero value. One story at 100% delivers deployable value. The unfeasibility triggers are critical — without them, swarming becomes dogma. If the story is blocked and agents are idle, they should pull the next item. The triggers give permission to diverge when swarming stops being productive.
The isolation branch pattern (branches off the feature branch, not develop) makes swarming compatible with gitflow. Multiple agents work on isolation branches that all merge back to the same feature branch, keeping the swarm unified.
