This answer is based on the best practice of conflict resolution in project management, which is to use a collaborative or problem-solving approach that seeks a win-win outcome for all parties involved12.

The velocity chart typically shows the amount of work completed over time.

A focus group is a technique that involves bringing together a group of stakeholders and facilitating a discussion to elicit their opinions, needs, and expectations about the project. This technique can help to gather requirements from stakeholders in an interactive and collaborative way1, p. 67

The statement of work (SOW) would be the next document that a project manager should update once the
need to procure goods and/or services is identified. A SOW is a document that defines the scope, deliverables,
schedule, and terms and conditions of a project or contract. A SOW typically includes information such as
purpose, scope of work, location of work, period of performance, deliverables schedule, applicable standards,
acceptance criteria, special requirements, and payment schedule. A SOW can help to establish a common
understanding and agreement between the client and the service provider on what needs to be done and how it
will be done.
