The business scorecard just seems like it is measuring a set of key results. If it’s a KPI the team is trying to achieve then how is that different than a key result?
For example I’m sure Doerr recommends regular syncs on the status of your KRs.
They are intended to be both a way of reviewing the work in a planning period, and also determining what is red and needing attention within the planning period.
Tactical/team-facing KRs could be measured daily if you need to, though the CEO wouldn’t want that report.
