Key stats

40.9 average weekly hours worked in PSA December 2024 data
NIST supports periodic access review

Headline finding

A quality sample is useful only when its dimensions are explicit. Speed, tone, policy adherence, evidence, and escalation should be scored separately so a strong average does not hide a dangerous defect.

Evidence and method

PSA hours are contextual rather than a service promise. NIST control principles inform reviewer access and sampling records. We recommend a stratified sample across routine, returned, and escalated cases.

Sampling design

Select cases by channel, age, outcome, and exception status. Record the rule applied, customer impact, evidence link, reviewer decision, and coaching action. Increase sampling after a material defect.

Key takeaways

Set a quality floor before optimizing speed. Keep compensation, refunds, and policy exceptions with an authorized owner unless the written workflow says otherwise.

FAQs

Is a five-case sample always enough? No; risk and defect history should determine the sample. Can customer sentiment replace policy review? No; it is one signal.
