End to end on the longest path: about 5.1 d of proposed target service levels. Gates wait for the people named; bars with a fading end have no fixed length.

Steps
  1. Define scope and question
    Scope · You · instant
    Entities: countries, ADM areas, sites or assets · Question and decision the index serves · Risk-chain components to cover
    Index Studio
  2. Select indicators

    Each input's licence checked for the use · Coverage per entity measured · Gaps flagged, never zero-filled

The canvas shows where a request stands at the marked job; it is an illustration, not the status of a real request. Durations are proposed target service levels. Select a job for its steps, the people who act, the technology it runs on and what it produces.
