If you’re a tester, and you’re not invited to attend planning sessions, stand-ups, or design meetings, you might be in a situation where testers are viewed as somehow apart from the development team. If you are invited to these meetings but you’re not speaking up, then you’re probably creating a perception that you aren’t really part of the team. If business experts are writing stories and defining requirements all by themselves, you aren’t participating as a tester who’s a member of an agile team.
