An article by Barclay Blair called Pulling out the red pencil: one more last time on the definition of Information Governance? links to various posts about what IG does and does not mean.
93% of those asked agreed on the definition put forward by the Information Governance Initiative, which was:
The activities and technologies that organisations employ to maximise the value of their information while minimising associated risks and costs.
None of us but Barclay is likely to read all the linked posts, but I particularly commend those by George Parapadakis which are referred to in Barclay’s article.
