One thing we have found to be useful is to first have a good, credible, regular system of information on service delivery. This takes considerable (years of) efforts, patience and some incentives to make it happen. However, once you have this system and stakeholders believe in its credibility, it is gradually used. The information system will need to be simple and online as far as possible to make it really useful. Such a system also helps create a culture where regular and useful information is available when needed.
