To ensure a successful transition to scrum, which step could an organization have taken?

Coaching the teams on scrum practices is essential for a successful transition to scrum because it helps team members understand the framework's principles, values, and specific roles. This guidance is critical for fostering a shared understanding and ensuring that everyone is aligned with scrum methodologies. Through coaching, teams can learn how to effectively collaborate, engage in ceremonies like daily stand-ups and retrospectives, and understand the importance of artifacts such as the product backlog and sprint backlog. This foundational support enables teams to apply scrum effectively, leading to improved performance and project outcomes.

In contrast, providing extensive documentation may hinder agility rather than facilitate it, as scrum emphasizes working software over comprehensive documentation. Implementing agile software immediately can overwhelm teams that are not yet prepared for such changes, leading to confusion and resistance. Additionally, changing all roles in the organization could disrupt existing team dynamics and create resistance rather than fostering a supportive environment for scrum practices. Therefore, coaching is the most effective strategy for easing the transition and preparing teams to thrive in a scrum framework.
