^ [[4 Project Organisation and Roles]] # 4.2  Project Organisation- Layers and Roles The diagram below provides an overview of the layers and main roles in project organisation from a project management point of view. ![[Fig 4.1 Project organisation.png]] Note that there is **only one project team**, which is composed of the people assuming the roles defined in the **Performing**, **Managing** and **Directing layers**. For the project to succeed, these people need to work together as a team. ## Business Governing Layer The Business Governing Layer determines the **vision and strategy for the organisation** as a whole. It consists of one or more management committees operating at a high or the highest management level. It is here that **priorities** are defined, **investment decisions** are made, and **resources** are allocated. ## Steering Layer The Steering Layer provides general **project direction and guidance**. It keeps the project focused on its objectives. It reports to the Appropriate Governance Body (AGB). ==The Steering Layer is composed of the roles defined in the **Directing** and **Management Layers** plus other optional roles==. ## Directing Layer The [[Directing Layer]] **champions the project and owns its [[Business Case]]**. It mobilises the necessary resources and ==monitors the project’s performance== in order to realise the project’s objectives. The Directing Layer **comprises the roles of Project Owner (PO) and Solution Provider (SP)**. ## Managing Layer The Managing Layer focuses on **day-to-day project management**. It ==organises, monitors and controls work to produce the intended deliverables and implement them in the business organisation==. Members of the Managing Layer report to the Directing Layer. The Managing Layer **comprises the roles of Business Manager (BM) and Project Manager (PM)**.
