"How many registers should I open today?"
A common question in retail. Can you explain the reasoning behind that decision?
Tenmaya Store Co., Ltd. is practicing "data-driven store operations" that go beyond shift creation, starting with time-based sales data. They introduced the shift management system "R-Shift" to their cashier department in the spring of 2023, and it's been about three years now. To mark this milestone, we interviewed the operational managers to learn about the changes that have occurred in the field and the reality of their initiatives.
## A Company That Has "Implemented" Data Utilization: Tenmaya Store
Tenmaya Store, which has supported Okayama
Tenmaya Store is a community-based supermarket chain with stores primarily in Okayama. While they have honed their on-site capabilities over many years, they have also been early adopters of data utilization.
They not only optimize shift operations for cashier duties but also utilize data for automatic ordering and sales floor management, thereby enhancing the accuracy of overall store operations. A key characteristic is that they haven't just advocated for DX but have deeply embedded it into their daily operations. As a result, they have consistently maintained a sales per person-hour level of approximately 19,000 to just under 20,000 JPY. Compared to food supermarkets of similar scale and in similar trade areas, they achieve high productivity.
