    Estimation anti-patterns: Fractal Estimation

    Fractal Estimation

    After the scope of the project has been constructed, some stories may be considered too large to fit into an iteration, so the team decide to split them into the smallest possible deliverable slices, re-estimating each slice. Of course, this is a bit like measuring the coast of Britain. The epic which was 13 points at project inception becomes 16 points of features, and 23 points of stories by the time it’s done in the sprints. Analysts wonder where this extra scope came from, while advocates of burn-down charts tuck the growing scope away somewhere where it won’t be noticed.

    The coastline of Britain gets longer as the increments in which it's measured get smaller.
