What is one of the Lean budget Guardrails?

This statement is one of the Lean budget Guardrails, which describe the policies and practices for budgeting, spending, and governance for a specific portfolio1. Continuous Business Owner engagement means that the Business Owners, who are key stakeholders for each Agile Release Train (ART), are actively involved in the planning, execution, and review of the value delivery1. They provide feedback, guidance, and approval for the PI objectives, features, and enablers, as well as participate in the Inspect and Adapt (I&A) workshop and the Program Increment (PI) system demo2. Continuous Business Owner engagement helps ensure alignment, transparency, and accountability for the value streams and ARTs1. References: Lean Budget Guardrails, Business Owners
