Key Performance Indicators are used to monitor and compare the performance of NWSDB with other foreign Water Authorities. They can also be used to compare the performance of various Regional Support Centers within the Board. The Cooperate Plan prepared for the period from 2007 to 2011 stipulates targets for each RSC and the Board. Board has started to monitor the performance indicators commencing from January 2011. Indicators are generally prepared for each quarter. Following table shows Key Performance Indicators for western Central RSC together with RSC target and Board overall Target.
