The keyword "scrum" also pops up, highlighting a shift towards agile methodologies in team management. Other key terms like "product backlog" and "product development" suggest a focus on designing and delivering better products, which is always a good thing. All in all, the Retrospective category is about taking a step back to move forward, with a focus on optimizing and refining whatever it is you're working on.
