This publication introduces the Minimum Viable Skillsets (MVS) methodology, which defines essential profiles for research data professionals—individuals whose roles involve creating, collecting, or using research data, often as evidence. Each MVS profile centres on key elements of a role that supports Open Science. This briefing outlines the purpose, scope, and structure of these profiles. It addresses questions from Competence Centres regarding how MVS profiles can be utilized in skills development and the collaborative approach behind their creation.
