The Iteration Retrospective is a core event in SAFe® and Scrum where the team reflects on the past iteration to identify ways to improve processes, collaboration, and effectiveness. One of the most powerful ways to transform retrospective insights into action is by writing improvement Stories.

An improvement Story is treated like any other backlog item—it is estimated, prioritized, and included in the upcoming iteration backlog to ensure continuous, measurable progress toward higher performance. This approach aligns with SAFe’s focus on Relentless Improvement, a pillar of the SAFe House of Lean.

From SAFe guidance:

“Teams record improvement items as stories and include them in the next iteration backlog. This ensures that improvement work receives visibility, commitment, and action.”

Thus, the correct answer is B. By writing improvement Stories, as it ensures improvement actions are tangible, trackable, and continuously implemented.
