Example talking point:
Scrum is ideal in some settings but teams should be continuously learning and adapting in order to accomodate/solve their obstacles. That evolution is often a response to common pressures in the workplace — I’m thinking of (1) interruptions, or (2) time-based/event-based tasks which can take precedence over the tasks already in a sprint backlog, or (3) a need to comply with contractual obligations written in conventional and hardly-agile legalise. So when a team is interrupted, or must accomodate events outside their sprint plan - then what? Well, then they evolve to either solve or ignore those obstacles.
If we could watch a Scrum team evolve — like watching a flower blossom a la time-lapse photography — and also watch the evolution of teams in Six Sigma or XP environments, will they gradually begin to look more or less like each other…or would they all evolve toward becoming OpenAgile?
