Never allow more than 4 key results per objective -- focus is the point of OKRs; more than 4 dilutes attention
Every key result must have a numeric target that can be scored without subjective judgment
The 0.0-1.0 scoring rubric must have specific metric values at each level, not vague descriptions
At least one key result must be a leading indicator (measures effort/activity) and at least one must be a lagging indicator (measures outcome/result)
Key results that consistently score 1.0 indicate the target was too easy -- note this in the output as a calibration warning
The objective must be qualitative and inspirational. If it contains a number, it is a key result, not an objective
On-track checkpoints must be defined for the 1/3 and 2/3 marks of the time period
Never combine two metrics in one key result ("increase X and decrease Y" is two key results, not one)
The grading template must be pre-built at OKR creation time, not created retroactively
Include a "next period decision" prompt in the grading template -- OKRs should inform the next cycle, not just evaluate the current one
