Data cart - designing a tool for the GDPR-compliant handling of personal data by employees

Employees who process personal data as part of their job play a critical role in protecting privacy. They are expected to follow strict data protection guidelines and protect personal data adequately. However, few studies have addressed the needs of these employees in terms of appropriate tools to assist them in complying with privacy laws. To develop a suitable tool, we used a human-centred design approach and held a series of eight workshops with 19 employees from two German public institutions. Based on the metaphor of a data cart, we developed a concept for a tool that supports employees in data management and data protection compliance. Qualitative usability testing revealed that participants expected the tool to raise their data protection awareness, reduce errors, and increase work efficiency. Our findings also suggest that if Privacy by Design becomes an integral part of digitalisation, employee perceptions of data protection may be positively altered. Employers, IT engineers, and researchers benefit from gaining insights into ways to improve the usability of data protection compliant personal data management tools. Simultaneously, we highlight how they can improve and promote compliance.
