This is a legal requirement under General Data Protection Regulation (GDPR) and fosters users? trust in the system. Transparency, when used correctly, is a tool to achieve this. The adoption of agile approaches, focused on coding and rapidly evolving functionality in situations where requirements are unclear or fast changing, poses new problems for the systematic elicitation and implementation of transparency requirements which are driven by, but lag behind, the functionality. We propose requirements patterns addressing GDPR?s principle of transparency by default, i.e., through a systematic and structured approach based on the artefacts of agile development. We present a case study using a SCRUM process to demonstrate the effectiveness and usability of the patterns.
