A performance report is easy to consume.

Performance has little ambiguity.

Performance is comparable and convertible.

Performance is fair.

Not that non-performance, or non-measurable issues or descriptions are not
important. They’re meant to highlight the scenarios where performance can be
more useful.

1. A performance report is easy to consume

Performance metrics are numbers. Reading a number is much easier than reading a
passage. For example, it probably takes an engineer 1 second to consume the
performance rating as a number from 1 to 5. It probably takes the same engineer
at least 1 minute to read the full, 500-word feedback summary.
