What is one way to address substantial rework?

One way to address substantial rework is to regularly engage with the Customer and Business Owner, who are the key stakeholders of the Agile team. By involving them in the feedback loops, such as the Team and System Demos, the team can validate their assumptions, get early and frequent feedback, and incorporate changes as needed. This helps to avoid building the wrong thing or building it incorrectly, which can lead to rework and waste. References: SAFe for Teams Student Workbook: materials and exercises from Lesson 6; [v5.scaledagileframework.com/get-feedback/]; [v5.scaledagileframework.com/team-and-technical-agility/]
