For every headline measure, define the business question, formula, unit, denominator, period, inclusion and exclusion rules, source tables or events, owner, refresh time, and known limitations. Terms such as active customer, qualified opportunity, completed work, recognized revenue, and automation success need company-specific definitions rather than assumed common meaning.
Link measures to the events that change them. A sales stage change, invoice, payment, delivery confirmation, support resolution, or release decision can carry different operational and financial meaning. Event lineage lets reviewers investigate movement and prevents the reporting layer from becoming an untraceable second ledger.
Name the expected direction only when the business logic supports one. A lower support backlog may reflect better resolution, lower demand, missing intake, or bulk closure. A higher pipeline may reflect growth, weaker qualification, or delayed cleanup. The dictionary should help readers ask which explanation has evidence before the narrative assigns meaning.
