Outcome orientation - you measure products by business outcomes, not technical output: defining outcome-driven metrics with stakeholders, tracking product KPIs (adoption, usage, quality, service levels, cost-to-serve), producing usage reporting and portfolio scorecards, and telling credible value stories. A portfolio of real product artifacts - you have personally authored the working documents of this discipline: product one-pagers and business cases with quantified ROI, PRDs with acceptance criteria, data contract and semantic specifications, metric dictionaries with agreed formulas and owners, adoption and usage dashboards, and sunset/retirement plans.
