The 7 themes help organizations to identify key roles, responsibilities, and give very practical guidance illustrating how MSP can be used according to the reasons for a programme. The 7 processes provide a route through the lifecycle of a programme with an emphasis on the incremental nature of a programme enabling a cyclical progression towards the desired future state.
