|---|---|---|---|---|
Purposedifferent | When many tasks need to be classified quickly, it sorts them by perceived effort and similarity. It reduces the effort of fine-grained estimation for large volumes. | When many people in a group too rarely get to speak, 1-2-4-All distributes thinking time more fairly. The format builds participation step by step and makes quiet or still-unformed thoughts usable faster. | When loud voices or hierarchy distort the idea search, the method creates a quiet entry into joint development. It gives everyone thinking space and gathers contributions without social brakes, making diversity more visible and easier to build on. | When a large batch of work needs a fast, rough estimate, it sorts items into predefined size buckets. It sorts work by value, risk, and delivery ability. The result is captured as a Bucketed Backlog, Relative Estimates, and Split Candidates. |
