I can vouch for that statement. A daily standup that exceeds 30 mins, a grooming and planning meeting that extends all 8 hours of a day in a sprint with unclear stories, surprise bug triage meetings ranging between 30 mins to 2 hrs, meetings where I cant possibly contribute, updating user stories with questions about the story, convincing people on why we shouldn’t be working on backend and ui without well defined contracts all account for over 30% to 60% of my time on a team with over 4 members.
