Hitachi Solutions, Ltd. (Headquarters: Shinagawa-ku, Tokyo, President: Eiji Morita / hereafter, Hitachi Solutions) has introduced the iPaaS 'Workato', which enables all types of data integration and automation on a single platform, to major general contractor Shimizu Corporation (Headquarters: Chuo-ku, Tokyo, President: Tatsuya Niimura, hereafter, Shimizu Corporation).
Under its 'Medium-Term DX Strategy', Shimizu Corporation has been working on building a data utilization platform as the core of its strategy, but faced challenges in integrating data scattered across various systems such as on-premise and the cloud.
Therefore, they introduced Workato, which features over 1,000 types of connectors and links SaaS, on-premise, and generative AI, advancing the implementation of data integration processing. With the support of Hitachi Solutions, they are operating various automation recipes in-house and expanding use cases utilizing generative AI. For example, they have realized a mechanism that analyzes system maintenance notification emails using an LLM*1 and automatically notifies operators via a chat tool depending on the degree of urgency. The company places high expectations on Workato as the internal standard environment for data integration and AI utilization, and is working to accelerate data utilization on a company-wide scale and business automation leveraging AI.
Hitachi Solutions will continue to promote DX through the utilization of AI together with Shimizu Corporation and contribute to the realization of SX management.

■ Implementation Effects
1. Integrates data scattered across diverse systems from on-premise to the cloud, realizing the automation of business processes utilizing AI.
2. Enables even frontline personnel to develop recipes using no-code/low-code, promoting the internalization of business automation by employees.
3. Builds a platform for future AI utilization that can flexibly integrate with diverse systems while achieving both shortened lead times through development efficiency and governance.
■ Background
DX in the construction industry is an essential initiative from the perspective of improving productivity and addressing labor shortages. Shimizu Corporation has promoted DX under the concept of a 'Digital General Contractor' within its 'Medium-Term DX Strategy'. Among these, building a data utilization platform is one of the most important measures at the core of various initiatives.
At the company, because data was distributed across multiple systems, it previously took a lot of time to extract data as the location of the necessary data and the contact points for inquiries were unknown. As a first step in developing the data utilization platform, they introduced a data virtualization solution to realize an environment for managing the latest and accurate data. However, as data utilization progressed, cases that could not be fully handled, such as the collection and processing of large-scale data and data integration between cloud services, became apparent.
Therefore, Shimizu Corporation adopted Workato, which can integrate diverse systems, anticipating the establishment of in-house development by employees. In addition to the abundant connectors and ease of development, the extensive know-how possessed by Hitachi Solutions was highly evaluated, leading to its adoption.
■ Comments from the Customer
We have received a comment from Mr. Yoshitaka Okazaki, General Manager, Advanced Technology Application Department, DX Management Promotion Office, Shimizu Corporation.
'We felt a sense of security because Hitachi Solutions shared their own experience of utilizing Workato internally. Moving forward, in addition to using it as a mechanism for data utilization, we also plan to use it as an AI agent environment. To support diverse use cases, we want to continue thinking and working together with Hitachi Solutions, who possesses a wide range of expertise, in the future as well.'
