estimation

Turns backlog, sprint work, and team flow into a tangible result by presenting the item, clarifying questions, and discussing deviations before estimating again.

Core question: How large is this item relative to our reference stories, and which assumptions or risks drive variance within the group?

Turns backlog, sprint work, and team flow into a tangible result by explaining the scale, choosing reference items, and marking large items.

Core question: Which size class does each item fall into relative to our references, and which items are so large that they must be cut before planning?

Turns backlog, sprint work, and team flow into a tangible result by preparing items as cards, building a relative size axis, and clarifying outliers and uncertainties.

Core question: How can the team place the items in a reliable relative size order and label the resulting groups?

Moves options, criteria, and risks toward a concrete result through "clarify the estimate object and unit", "collect independent estimates", and "document another round and the outcome".

Core question: Which range and expected value describe the estimation object most honestly under explicit expert assumptions?

Moves options, criteria, and risks toward a concrete result through "clarify the estimate object", "determine the optimistic value", and "derive the range, expected value, and risks".

Core question: Which realistic range from optimistic to pessimistic describes the estimation object, and which risks drive the difference between the three values?

Moves options, criteria, and risks toward a concrete result through "collect three values", "explain the formula", and "document the planning assumption".

Core question: What weighted expected value and confidence interval result from the three estimate values, and is that enough for the planning decision at hand?

Moves backlog, sprint work, and team flow toward a concrete result through "prepare buckets and scale", "place reference items", and "flag large or unclear items".

Core question: Which bucket does each item belong to relative to our references, and which items are so large or unclear that they need to be sliced or clarified before planning?

30-90 min

Moves group input, selection, and decision toward a concrete result through "make items visible", "clarify what the dots mean", and "discuss large or risky items".

Core question: Which items does the group indicate as especially effortful, risky, or unclear, and where are clusters or outliers that need discussion or discovery?

Moves backlog, sprint work, and team flow toward a concrete result through "explain the ideal day unit", "calibrate with a reference item", and "do not confuse it with calendar days".

Core question: How many ideal days are needed for this item under focused work, and what assumptions about interruptions, dependencies, and uncertainty are made?

15-60 min

Moves backlog, sprint work, and team flow toward a concrete result through "choose reference stories", "define the scale", and "interpret velocity only within the team".

Core question: How large is this item relative to our reference stories, considering scope, complexity, risk and uncertainty?

Moves backlog, sprint work, and team flow toward a concrete result through "clarify the planning question", "slice work smaller", and "calibrate regularly with reality".

Core question: Which planning decision do we need to make, and which flow data or slicing rules answer it more cheaply than an estimation ritual?
