A publicly traded Mexican grocery store and department store chain, which also operates stores in California, Arizona, and Nevada, required the support of RGIS.
THE CHALLENGE
The supermarket chain required support from RGIS to complete internal audits within all stores, as the internal audit team had limited budget and team capacity. The requirements were as follows:
- To complete internal audits in all 262 stores
- Double the 10% internal audits completed
- Audits to be completed in sales, stock, incomes and expenditures
- Accurate reporting for all audits
Why RGIS?
Customers use RGIS for internal audits to extend audit coverage with independent, objective expertise without increasing internal headcount. This provides accurate insight into compliance, risk, and operational performance across locations.
