Tosoh Adopts TechTouch to Support SAP S/4HANA Adoption and Improve Around 23,000 Annual WBS Registration Tasks

TechTouch Inc. announced that Tosoh Corporation, a comprehensive chemical manufacturer, has adopted TechTouch to support user adoption of its core ERP system, SAP S/4HANA. Through the implementation, Tosoh aims to eliminate confusion in WBS registration tasks for project management, which total around 23,000 cases annually, reduce users’ psychological burden, cut input workload, and improve data accuracy. As background to the implementation, Tosoh has positioned “strengthening existing businesses through the use of digital technologies” as one pillar of its DX strategy in its medium-term management plan. As part of this effort, the company is renewing its core system to SAP S/4HANA to strengthen the business foundation across the group and accelerate decision-making. In the chemical manufacturing industry, work such as capital investment, maintenance, and renovations is often managed on a project basis, making WBS registration a frequent task in the project management (PS) domain. However, this area involves many complex input operations, including WBS linkage and project-specific date definitions, creating a significant burden for frontline employees. With around 23,000 WBS registration opportunities each year, hesitation and errors in operation can not only increase input workload but also hinder accurate, real-time data accumulation, potentially delaying project management and decision-making. Tosoh therefore concluded that, in order to fully realize the benefits of its system renewal, it needed an environment where frontline employees could operate the system intuitively, without confusion or unnecessary burden. The company decided to introduce TechTouch, which can guide operations in real time directly on the screen without relying on manuals. A key factor in the adoption was TechTouch’s ability to display real-time navigation within the system. This was highly evaluated as a way to move away from the traditional approach of operating systems while referring to existing manuals. In particular, even for complex procedures involving actions such as right-clicking and drag-and-drop, which are difficult to judge mechanically, TechTouch enables users to complete tasks without confusion. This usability was seen as essential to reducing workload at the frontline. The ability to implement guides with no code is also expected to enable agile improvements that reflect on-site needs. With TechTouch, Tosoh has established an environment that reduces users’ psychological burden during complex operations and supports intuitive work execution. For approximately 23,000 WBS registration tasks per year, real-time navigation is expected to reduce the time spent searching manuals, prevent input errors caused by uncertainty around items such as date definitions, and reduce inquiries to the information systems department. Going forward, Tosoh will visualize the workload reduction effects in this large volume of registration work and shift the time created toward higher-value tasks, accelerating DX across the organization. A representative from Tosoh’s IT Management Division said that the implementation of SAP S/4HANA is an important initiative for strengthening the company’s business foundation. At the same time, for complex tasks that occur daily in the field, such as WBS registration, Tosoh recognized the need for a more intuitive and less burdensome operating environment. Through the introduction of TechTouch, the company expects to reduce input workload, suppress operational errors, and improve both frontline productivity and data accuracy. Tosoh is a comprehensive chemical manufacturer whose corporate philosophy is to “contribute to society by realizing happiness through chemical innovation.” Since its founding in 1935, the company has provided products and technologies that support the foundations of society and industry, centered on vinyl, isocyanate chains, petrochemicals, and specialty products.
