Acquisition Operating Framework (AOF)
The AOF is the authoritative source of policy and guidance on acquisition for the UK MOD and our Industry partners.
The AOF defines how we conduct, govern and control our Defence acquisition process and is a key enabler for improving our delivery to the Armed Forces and for producing greater value for money for the taxpayer.
