  2. Risk Appetite advanced

    A board sets an appetite of at most two customer-visible material incidents a year. Engineering ships about 3000 production changes a year with a change failure rate near 15%. Roughly how many material incidents does that imply, and which lever actually closes the gap?

  3. Risk Appetite advanced

    A board's risk appetite statement allows at most four hours of customer-visible unavailability per year for the payments API.
