Timeboxing discussions is a key Agile development practice that supports efficiency, focus, and predictability in team events and collaboration. A timebox sets a maximum duration for an activity, ensuring that meetings or working sessions remain purposeful and do not overrun.
Agile and SAFe both emphasize timeboxing for events such as Iteration Planning, Daily Team Syncs, Iteration Reviews, and Retrospectives. This discipline encourages concise communication, prioritization of topics, and respect for everyone's time.
From SAFe guidance:
"Agile Teams use timeboxing to help ensure meetings are effective and efficient, maintain focus on outcomes, and support a predictable rhythm for collaboration." Other options such as sequencing processes or exploring diagnostics do not represent standard Agile team development practices. Facilitating meetings is a Scrum Master responsibility, not a development practice.
Thus, the correct answer is D. Timeboxing discussions.
