At project kickoff the sponsor stresses that demonstrating product benefits is critical. Because the project has high uncertainty and expected changes, what approach should the project manager propose?

An agile approach is best suited for projects with high uncertainty and expected changes because it allows for iterative delivery and continuous feedback. This enables the project team to demonstrate product benefits early and frequently, aligning with the sponsor's emphasis. Developing requirements and designs for faster releases is a good practice but doesn't address the underlying uncertainty and need for iterative feedback as effectively as an agile approach. Outsourcing might bring expertise but doesn't inherently solve the problem of managing high uncertainty and changing requirements. A predictive approach, while good for reducing ambiguity in stable environments, is ill-suited for projects with high uncertainty and expected changes, as it relies on upfront planning and fixed requirements.
