Digital services for communication and collaboration are now used in almost every project. From a data protection perspective, however, their use must be well thought out and clear agreements, measures and instructions must be in place to ensure the security of the data processed there.
The project partners usually agree on the internal use of communication and collaboration services at the start of the project. In practice, detailed information about data processing is often not provided. However, as soon as people outside the project use these services, you must fulfil the information obligation as specified. For example, if you invite external parties to your video conferencing solution, you as the controller must provide the data subjects with appropriate data protection information.
The same applies here: document all data protection-relevant topics. These can serve as a basis for future projects.
