Effective visual signals are important for effective management improvement: lean thinking emphasizes such ideas. Top 5 Rules of Effective Measurement Boards is an excellent post on how to make measurement effective.

Post the important data for everyone to see. Review the data as changes are made and see that the changes had the desired result. Update the measures when appropriate (for posting visibly – you will of course be measuring more than the few measures that belong on measurement boards).
