After a company adopted agile for innovation projects, some team members consider certain agile ceremonies unnecessary. What should the project manager have done before the project started?

The correct answer is preparing an inception deck and clearly explaining the purpose and benefits of agile ceremonies. Before starting an agile project, it's crucial to ensure the team understands the "why" behind agile practices. An inception deck, or similar project charter, provides a foundational understanding of the project's vision, goals, and the chosen methodology, including the value of agile ceremonies. This proactive communication helps build buy-in and prevents resistance. Discussing with the sponsor or product owner to convince or require adoption is reactive and less effective than upfront education. While a survey might gauge willingness, it doesn't address the root cause of potential resistance, which is a lack of understanding of the benefits.
