If the ceremonies are in place and the work is not faster, you do not have an agile team. You have a calendar.
The useful question is where value stalls. Handoffs, approval chains, a framework argument, a leader who still wants a fixed scope and a fixed date.
Training helps when it uses the team's real backlog, and when leaders are in the room. Coaching helps when the new habits have to survive the first busy month.
What the hour is for
Frameworks are tools. Scrum, Kanban or a hybrid can all work. Orthodoxy does not ship.
Run the next step in a design thinking workshop on a live problem. If the bet is already named, test it in a lean startup product sprint. The check on a live draft sits in the critical thinking workshop.
Google's re:Work guide on team effectiveness is the study I still hand to a manager who thinks a tool will fix the room.
