Break Down the Problem

1. Identify the key stakeholders involved in a project who are responsible for adhering to customer milestones.
2. Evaluate the roles of each option provided (Functional managers, the Project team, and Project manager) in relation to meeting those milestones.

Relevant Concepts

1. Functional Managers: Oversee specific departments and may influence timelines but are not directly responsible for project milestones.
2. Project Team: Executes the work and must adhere to milestones throughout the project's lifecycle.
3. Project Manager: Primarily responsible for planning, executing, and closing projects, ensuring all team members and functional managers work towards agreements, including timelines.

Analysis and Detail

1. Functional Managers might support the project but are not formally accountable for milestone adherence.
2. The Project Team plays a direct role in executing tasks to meet milestones laid out in the project plan and reports to the Project Manager.
3. The Project Manager oversees the project, manages the team, and enforces adherence to milestones established by the customer.

Verify and Summarize

Given the roles, the Project Manager and the Project Team have direct accountability for meeting milestones established by the customer. The Functional Managers do not directly adhere to the milestones but support their achievement.

Final Answer

The correct answer is b. All the choices. Each role contributes to some extent in adhering to the agreed-upon milestones, making it a collective responsibility among all parties involved.
