After the changes have been implemented, continue to monitor the operations used in the development of the starting baseline data for the brewery.
Compare the new monitoring information against the starting baseline (i.e. before the changes were made).
Did the changes meet the goals? If yes, then this new data is the revised new baseline to measure further improvements against.
If not, consider and implement other priority changes. Then monitor and assess.
Monitoring activities can help provide new insights on 'cause and effect' between brewery operations and water management issues. Use these insights to update the priority list of improvement opportunities.
