Projects can involve large numbers of people often from different departments, functions and divisions of the business. The project manager is accountable for the project but this does not mean they are solely responsible for all the work involved. A Responsibility Matrix is used to define who in the organisation is responsible for individual work elements and deliverables. By forming a matrix with the work breakdown structure and the organisational breakdown structure, responsibilities can be assigned to lower level tasks. Each task is assigned a WBS and OBS code, the department responsible, the person responsible, and the scope of work required.
