In this situation, the project manager should communicate with the client about the third-party supplier's situation and request payment. This is because the agreement was that payment would be made after the organization receives payment from the client. By explaining the situation to the client, the project manager can potentially expedite the payment process and prevent the withdrawal of team members from the project, thereby minimizing project disruption.

Explanation:
The PMM is an organization-approved approach for project management that is used on every project. It is not part of the project scope statement, which describes the project scope, major deliverables, assumptions, and constraints. It describes the project's deliverables and the work required to complete them.

The agile leader should speak directly with the team member about improvements and commit to an agreed-upon time frame. This is the best option because it shows the agile leader's respect and empathy for the team member, as well as the willingness to help them overcome their challenges and grow their skills. By speaking directly with the team member, the agile leader can also understand the root cause of the problem, provide constructive feedback, and agree on a realistic and achievable plan for improvement. This option also aligns with the agile values of "individuals and interactions over processes and tools" and "responding to change over following a plan"1.
The other options are not as effective as option D. Option A is not supportive and may demotivate the team member and create resentment. Option B is not appropriate and may embarrass the team member and lower the team morale. Option C is not relevant and may not address the team member's specific needs and gaps.
