A cumulative flow chart shows a testing bottleneck in a self-organizing team. The team identifies a testing skill gap. What should the project manager do to address this?

The project manager's role in an agile environment is to serve the team and remove impediments. By supporting the team in identifying an approach, the project manager empowers the self-organizing team to find their own solution, fostering ownership and continuous improvement. Asking the development team to slow down only masks the problem and reduces overall throughput. Providing training to the entire team or onboarding a new team member are potential solutions, but these should be identified by the team as the most appropriate course of action, not dictated by the project manager. The project manager facilitates, not dictates.
