Most quality programmes ask managers to review a handful of calls per person per month. The sample is small, the criteria drift between reviewers, and the time cost is real.
What results is a score that nobody fully trusts and everybody spends hours producing.
When every call is assessed against the same criteria, the discussion moves from whether the sample was fair to what the pattern means.
It also removes the reporting burden entirely, which is usually the part teams resent most.
