For years I've helped individuals and organizations solve gnarly problems through data (even wrote a book about it). Most industries have standard success measures (sales, productivity, customer satisfaction, etc.) and those are a great place to start. Here is a brief list of common KPIs and how to think about them.
From 67% satisfied customers (bad)
to 92% satisfied customers (much better)
~ On a project to improve long-standing poor customer satisfaction the data revealed policies that prevented customer service agents from giving customers what they wanted.
~ I re-wrote those policies (with product team buy-in) and identified technical training that would raise the standard of service.
~ Over a few months, customers consistently scored the team higher in customer satisfaction due to the changes.
All actions in an organization should either drive revenue in, or drive cost out. Which one is yours?
