An analogy for explaining why value-creation work and value-protection work aren't a trade-off: value creation (new features, innovation) is like discretionary spending — Netflix, eating out — while value protection (tech debt, compliance, keeping the lights on) is like cost-of-living spending — rent, utilities. A household budget funds both simultaneously; neither is "extra" once the other is covered.
Used to argue that Three Buckets of Product Work: New, Existing, Protect Value aren't competing priorities to be traded off against each other, but parallel line items that both need standing budget. Pairs with First Rule of Tech Debt: you can only budget for tech debt once it's named out loud.
Use it with stakeholders who frame tech-debt/protect-value work as something to fund only after innovation work is "done" — reframe it as a parallel, non-negotiable budget line, the way rent doesn't wait for discretionary spending to be approved first.
