Be aware of the wider information environment. Does what you are proposing to produce fill an information gap – or complement and support existing related resources produced by your own organisation / sector or which may be available more widely?
Consider if you really need to produce a new resource. Where possible, consider adapting existing resources (with permission and acknowledgement) so that they are suitable for your audience.
Also consider whether you can signpost your users to existing sources of information, services and support – either as well as, or instead of, producing new material? For example, you may be producing information on clinical issues for people who might also have wider information needs about available financial help or other quality of life issues.
