Daiwa House Industry Co., Ltd. is a pioneer of prefab housing. Daiwa House aims to support people ' s lives, not only through their core business of detached single-family homes but recently through the development of rental housing and commercial facilities, and even home care services and lifestyle-supporting robots. Daiwa House, which will celebrate its 60 years anniversary in 2015, has established the management strategies of promoting global business development and boosting group partnerships to achieve further growth and offer superb value-added products to meet diverse needs. Daiwa House is particularly focusing on China, America, Australia, and Taiwan, as well as emerging economies such as Vietnam and Indonesia. As the IT system supports these management strategies, Daiwa House makes advanced use of the latest technologies. Currently, the company uses systems like SAP at a centralized data center in Japan. All their offices, in Japan and overseas, need to access it, so the infrastructure connecting them is a lifeline for their business. However, issues had started to arise. " Especially recently, with more cloud utilization, more CAD use and more teleconferencing, the amount of image, video, and voice data being exchanged had really ballooned, " says Mr. Kyoji Kato of Daiwa House Industry Co., Ltd. The company instituted a priority control between core systems data and image, video and voice data in order to eliminate any delay in mission-critical data such as accounting information, but was not able to keep pace with the rapid expansion of traffic, resulting in delays eve n in accounting while less important things like audio quality could not be assured either.
