• Tracking costs for the care of elderly for a Primary Care Health Trust (or whatever they are called these days)
  
• Bookings for a particular Citizen's Advice Bureau
• Tracking people, contact details and committees and posts for a particular Anglican diocese

These are all examples of systems that I have come across in recent weeks where a specific part of a loosely joined organisation is solving a specific problem which could benefit the whole organisation. Other people in other parts are doing the same thing and could probably benefit from that particular system, but what seems to be lacking in each of these cases is the central organisation to co-ordinate IT efforts. Not that going that way would be easy. If you had to do a system that satisfied 20, 30 or 500 clients, rather than one, then it would take longer, cost more and deliver less. There has to be a middle way though.
