Okayama-based supermarket Tenmaya Store has introduced the 'R-Shift' management system in its checkout department. This move towards data-driven staffing has increased productivity and eliminated person-dependent processes. Having used the system for about three years, the company maintains a high sales per person-hour of nearly ¥20,000, setting an example of successfully embedding DX into on-site operations.

"How many registers should we open today?"

This question, common in retail, begs another: can you explain the reasoning behind your decision?

Tenmaya Store Co., Ltd. is practicing "data-driven store operations" that go beyond just creating shifts, starting with hourly sales data. In the spring of 2023, they introduced the shift management system "R-Shift" to their checkout department, and it has now been about three years. To mark this milestone, we interviewed the operations managers to learn about the changes that have occurred on-site and the reality of their initiatives.

### ■ Tenmaya Store, a company that has "implemented" data utilization

Tenmaya Store is a community-based supermarket chain centered in Okayama. While they have honed their on-site capabilities for many years, they have also been early adopters of data utilization.

They use data not only to optimize shifts for checkout operations but also for automatic ordering and sales floor management, thereby increasing the precision of their overall store operations. A key characteristic is that they haven't just promoted so-called DX, but have firmly rooted it in their fieldwork. As a result, they have consistently maintained a sales per person-hour level of approximately ¥19,000 to just under ¥20,000. This demonstrates high productivity compared to other food supermarkets of similar size and in similar market areas.
