Who is it for?
You should already have established how the issue affects people, and what you are trying to do about it. Next, you need to think in more detail about who it is for and what their needs are.
Who are your audience?
It is important to be clear about who you are aiming your information at. Sometimes your target audience will be determined by your organisation - you may have a clearly defined client group you are trying to reach. At other times, it will be determined by the issue or what you are trying to do. If you are trying to help clients deal with a problem or use a process, it may be that the problem is predominantly experienced by a particular group.
Information sometimes fails when it tries to cater for too broad an audience, or for no specific audience at all.
The more targeted and specific you are, the more effective your information is likely to be.
Once you have decided who your audience is, you need to work out what their needs are.
