The Auditor General for Wales is investigating the Welsh Government's investment in super-fast broadband services.
Huw Vaughan Thomas is carrying out a value-for-money review of the £425 Superfast Cymru programme, which is designed to deliver fibre-optic services nationwide.
The Wales Audit Office is seeking to answer the question: 'Is the Welsh Government's approach to rolling out broadband infrastructure to households and businesses likely to deliver its intended benefits?'
It will consider the effectiveness of the current strategy and targets, the financial planning and governance structures for the programme, the contractual arrangements with BT for Superfast Cymru, the procurement processes and therisk management arrangements.
Around 1,000 households and businesses will be surveyed in the two areas where there has been significant progress on fibre broadband so far - Blaenau Gwent and Gwynedd.
The project team is also inviting members of the public to get in touch with any experiences they may have had of the Superfast Cymru programme.
A final report is due to be published by the Wales Audit Office by the end of 2014.
