In March 2003, the Strategic Investment Board Limited ("SIB" and "Strategic Investment Board") was established as a new company wholly owned by the Office of the First Minister and Deputy First Minister and funded through the Executive.
SIB's role is to inform and implement ministers' policy for public infrastructure in Northern Ireland. It does this by producing the Investment Strategy for Northern Ireland (ISNI); by supporting departments in the delivery of infrastructure projects and by promoting reform in infrastructure processes and structures.
