Together with Hollu Systemhygiene GmbH, we have developed the digital hygiene manager NOA. NOA unites and connects processes, team and knowledge and thus offers the highest level of hygiene safety in operations, in the hotel & catering industry and meets the strict requirements in retirement and nursing homes. With the digital hygiene manager NOA, the customers of Hollu Systemhygiene GmbH always have an overview of the hygiene processes in their business. Resources can be used more economically, NOA shows in real time which adjustments need to be made. Even complex hygiene measures are greatly simplified by NOA. Employees have access to digital cleaning plans and step-by-step instructions. New staff can be trained quickly and easily. The tasks completed and measurements taken in NOAguide, as well as the messages transmitted, are immediately available in the software and can be used for further measures. With the connection of IoT devices from the fall of 2020, further features await that will help cleaning personnel in their daily work.
