When would you adopt the Continuous Delivery Lean life cycle?

The Continuous Delivery Lean life cycle is suitable when there is an experienced team working on a product or service where the requirements change frequently, potentially daily. This life cycle supports frequent deployments and quick feedback loops, making it ideal for environments where requirements are dynamic and evolve rapidly. Options A, D, and E do not align with the conditions that necessitate a Continuous Delivery Lean approach, as they involve either less experienced teams or slower-evolving requirements.
