In today's construction industry, collaboration between the construction site and the office is considered crucial, and the use of a wide variety of IT devices and cloud services (SaaS) is essential for streamlining operations. However, the increasing number of devices and services used is also increasing the burden of managing them.

The Planning Section of the Management Department in the company's Corporate Administration Headquarters, which handles the role of the company's information systems department, had long been struggling with the management of IT assets and accounts. The company has approximately 420 full-time employees and about 100 temporary staff and staff from partner companies, totaling 520 users of its internal systems. In addition to each employee being provided with a PC, the total number of devices under management, including tablets, smartphones, and communication SIM cards used at construction site offices, amounts to approximately 1,000.

Previously, device and account management was entirely handled using multiple Excel files. Ken Tominaga, chief of the Planning Section, Management Department, Corporate Administration Headquarters, recalls, "When I joined the Company, the first thing I encountered was this proliferation of Excel files. There was a separate ledger for each device and service, including PCs, smartphones, SIM cards, and various SaaS accounts, and each had a different format. Because all of this was managed manually, omissions and forgotten updates frequently occurred."
