The project management team makes and carries out decisions.

To gain commitment to decisions, 3 differing interests must be represented on the Project Board:
- Business Executive - Focuses on whether the end project deliverable will offer "value for money".
- Senior User(s) - Focuses on whether the end project deliverable will offer something that is "fit for the users' purpose".
- Senior Supplier(s) - Focuses on whether the end project deliverable "can be done".
There are also essential roles in a project management team for monitoring all aspects of the project's performance independently of the Project Manager and dealing with requests for change and off-specifications. These roles are called Project Assurance and Change Authority respectively and are the responsibility of individual Project Board-members. Sometimes, the Project Board delegates these roles to other people who are independent of the project management team.
Other optional roles are Team Manager(s) and Project Support.

If you cannot afford them, their responsibilities fall to the Project Manager.
Once you have designed the team structure, put names to the roles and make sure each person signs up to their role's specific responsibilities.
