14 The strategic case for greater transparency is strong. If it is to do more than satisfy public rights to public information, however, and contribute fully to objectives set for it including accountability, service improvement, and growth, then the Government needs a firmer grip on measuring the success of the initiative. While it has begun to gather evidence of usage and benefits arising from the use of open data, it has not yet positioned this within a wider, systematic evaluative framework. Evidence on benefits should be considered alongside information on costs and risks to secure best value from the large stock of public data, match the range and presentation of data purposefully to fulfil specific objectives, ensure that risks are identified and mitigated, and secure value for money.
