The best way to ensure that the client is effectively represented in the daily meetings is to provide them with the necessary agile knowledge and skills to participate and collaborate with the vendor team. This can be done by proposing a session for essential agile knowledge transfer, where the vendor project manager can explain the agile principles, values, practices, and tools that will be used in the project. This will help the client team to understand the purpose and benefits of the daily meetings, as well as their roles and responsibilities in them. The other options are not as effective as they either do not address the root cause of the problem (lack of agile knowledge), or they introduce unnecessary changes or delays to the project (realigning the project or recommending training programs). References: PMI Agile Practice Guide, page 14-15; PMBOK Guide, page 18-19
