Common questions
What shrinkage pattern raises suspicion?+
A rate that is consistently higher at one location, for one product category, or under one manager than comparable peers, rather than the absolute shrinkage level on its own.
What non-fraud causes must be ruled out first?+
Ordinary breakage, spoilage, administrative counting errors and legitimate supplier shortages, before an elevated rate is attributed to theft or deliberate fraud.
