Personally I think the idea of a summary document to accompany reports is a good one. The public are likely to be interested in what problems have been identified and what solutions are being proposed but should be spared the minute details. In reality it would be very difficult to write a full report in such a way that a wide audience are likely to read it. Objectively I can say that having compiled the last two CfPS Library Monitors' that reading 70 page reports with 50 recommendations takes real stamina. A punchy summary document would surely resonate with the public and serve as a press release to the media.
I think the point Dave makes about signposting is important as there is not much point in making a document accessible if nobody outside the council is going to read it.
I would be interested hear what steps (apart from uploading reviews into the CfPS reviews library) people are taking to ensure their reports have maximum public exposure.
Finally, I think it should be acknowledged that writing accessible documents that are free of jargon is actually quite difficult. The Audit Commission have been talking up their attempts to make OnePlace accessible to the public by using plain English so that may be a useful benchmark for you http://oneplace.direct.gov.uk/Pages/default.aspx
