Planning adjustments are agreed upon during the management review and problem-solving meeting in the PI planning event. The management review and problem-solving meeting is a session that occurs at the end of day one of the PI planning event. In this session, the management team reviews the draft plans of all the teams in the ART, identifies any issues or risks that need to be resolved, and proposes any changes or adjustments that are necessary to achieve the program objectives. The management team then communicates their feedback and recommendations to the teams on day two of the PI planning event.  References : PI Planning, Management Review and Problem-Solving

SAFe describes DevOps as:

“DevOps tries to bridge the gap between new Features and stable solutions… DevOps joins development and operations to enable continuous delivery.”

This integration supports both speed and stability in software delivery.

“Precisely specify value by product” is central to Lean thinking. Lean thinking is a philosophy and a set of principles and practices that aim to eliminate waste and optimize value delivery. Value is defined as anything that a customer is willing to pay for or that meets their needs or desires. Value is specified by product, which means that each product or service should have a clear and explicit definition of what value it provides to the customer and how it differs from other products or services. Specifying value by product helps avoid ambiguity, confusion, and inefficiency in the value delivery process.  References : Thriving in the Digital Age, SAFe Principle #1

From the Agile Manifesto as stated in the SAFe Workbook:

“Customer collaboration over contract negotiation”

This is one of the four core value statements that define Agile methodology.

From the Workbook’s Portfolio Kanban section:

“Once an Epic is approved with a Lean business case, it moves to the ‘Ready’ state in the Portfolio Kanban system, provided it receives a ' go ' decision from Lean Portfolio Management (LPM).”

This marks the transition from analysis to readiness for implementation.

SAFe Principle #10 emphasizes:

“Organize around value” and states that enterprises must continuously adjust their organizational structure to optimize for the flow of value when market demands change.

This means reorganizing the network around the new value flow is the recommended approach.
