If your organization is following a more agile-centric methodology and there is no formal project management role, then who would manage a RAID log? In these cases, it’s typically the Product Owner and the SCRUM Master.
For the Product Owner, they can use RAID to manage their product, tracking risks, actions, issues and decisions needed to make the product succeed. For the SCRUM master or team lead, RAID tends to be more tactical, focusing on the things that help the agile team succeed, fueling those all-important retrospectives.
