A written internal standard for quality control process makes onboarding new account managers far quicker and reduces avoidable errors.
Why quality control process matters on the Meta 4

Seasonality interacts with quality control process more than most forecasts allow for, so a rolling review beats an annual one.
Functional testing of a sample from each batch is standard practice.
