Outcomes framework for infrastructure

How difficult can it be to write an outcomes framework for infrastructure orgs..? Basically we need:

1. 3-5 output indicators for each service are (volunteer centre, funding advice, governance, HR etc) and then we need to link them to the individual orgs.
2. customer satisfaction feedback (in the interim an annual survey, longer term google places or something).

Then we have two pages at the end of the year that says; we helped 400+ orgs to get better, do more work and help individuals to change their lives. simples..?
