Mistakes in fulfillment, driven by speed over accuracy, lead to unnecessary costs like reshipping, additional labor, and customer dissatisfaction. These errors become inevitable when there are insufficient checks and balances at key stages like picking and packing. Unlike initial shipping costs, correction costs accumulate, decreasing the operation's profitability and affecting customer trust. Over time, without a preventative model, the operational decay manifests as increased errors and lost revenue. Developing a robust preventative operating model with assigned ownership and SLAs mitigates these persistent issues.
