Yoshinoya Co., Ltd., a leader in the food service industry, has overcome numerous crises through a diverse range of management strategies. However, major management challenges remained, including communication loss among stores and employees. To become a company where employees can proactively solve problems through smooth communication between staff, crew, and headquarters, they introduced an interactive Time and Attendance Management System.
Company-wide implementation of an interactive Time and Attendance Management System focused on information sharing among employees
A corporate culture that “keeps its employment promises.” Introduction of an interactive Time and Attendance Management System.
Although proper labor management was attempted, shift management and staff support across stores were manually handled, making systematization difficult. Yoshinoya operates over 1,000 stores, and information sharing among headquarters, sales departments, and individual stores was extremely challenging. Therefore, they considered introducing an “interactive Time and Attendance Management System” as an all-participation labor management approach aimed at improving communication between stores, crew, and headquarters. The “Yoshinoya Way” values each individual’s role and pursues value through “daily improvements.” The top management priority was to promote communication among stores, crew, and headquarters.
Choosing a system development partner: the decisive factors were proven track record and responsiveness to needs
A wide variety of requirements were raised, including task-specific communication functions and functions to accept requests from crew members. However, building a system focused on “communication” required custom development beyond the capabilities of standard commercial packages. Also, a partner with extensive experience in the food service industry was preferred. GulfNet, which has implemented store systems for many companies in the food and distribution industries, was selected as a candidate.
The key to the system was how effectively communication between employees and stores could be achieved. Although it is a Time and Attendance Management System for stores, it required an interface that allowed smooth information sharing between employees, stores, and headquarters. With over 1,000 stores and more than 20,000 employees including part-timers, the system had to be scalable and operate without causing frustration.
In selecting a partner, advanced development capabilities to meet customer needs were emphasized. A proven track record in the food service industry was also important. As a result, GulfNet, which provides store systems to many companies in food service and distribution, was selected. Yoshinoya had a clear need: “We want to build an interactive Time and Attendance Management System that enables over 20,000 employees to participate in labor management.”

Customer Feedback
“When considering this system, we started by evaluating whether to go with a scratch-built solution or a packaged system. Because we faced the challenge of short development and implementation time, we chose to customize an existing package. During system concept development discussions, key points included: linking with automatically calculated average number of daily customers based on past performance data, reducing workload in optimal shift and schedule creation, improving the speed of information sharing through schedule adjustment functions across stores (support assignments), and controlling monthly labor hours by aggregating actual performance with planned future shifts.
As we searched for a proven package, we discovered ‘Gulf CSM Time and Attendance Management’. As a base package, it was ideal. Although customization and add-on development were necessary, the SE team fully understood our concept and approached the development with genuine enthusiasm and dedication.”
