6 The Aquamark Framework is designed to examine whole of business process capability, documentation, and execution.

7 ACCOMPLISHMENTS

8 We Developed an Asset-Centric Strategic Plan We collected the thoughts and ideas of employees throughout MSD GE CAP Sessions & Level of Service Workshop Asset Management Boot Camp Week We brought in local universities and nationally-recognized experts University of Cincinnati (Net Present Value) Miami (OH) University (financial sessions) Xavier (OH) University (CIP workflow) We collaborated with the local USEPA office. Goal Areas 1. Infrastructure 2. Workforce 3. Stakeholders and Sustainability 4. Communications 5. Financial 6. Continuous Improvement

11 The Asset Life Cycle Maintenance Strategy needs developed prior to start-up Asset cared for by operations and maintenance. Care of the Asset New Asset Commissioned Operate Maintain Modify Asset No Longer Useful Create Asset Dispose Design Evaluate Plan Strategy Best Asset Design And Creation Develop the Optimal Asset Mix Source: Sustainable Asset Management, Roopchan Lutchman

12 Business need for new process Key O&M documents delivered after construction Maintenance strategy not in place for months after start-up Some equipment failed early in its life Operations, maintenance, and engineering poorly coordinated Past Documents were paper copies. Did not receive until weeks or months after start-up Documents not tied to asset or location numbers Process not in place to convert O&M documents into executable maintenance strategy Lack of baseline testing Routine maintenance (PM, PDM) not in place at start-up Contract requirements inadequate Engineering did not understand needs Maintenance and Operations not prepared to take over assets.

13 Process Development Team Based Approach Utilized Involved maintenance, engineering, and legal. Peer reviews External expert review Internal and external education Senior management Middle management Consultants

14 Barriers Eliminated Improved Standard Construction Project Specifications Improved Timelines Electronic Format Document Control library External Support Contracts put into place Funding Source put into place Process aligned with Organizational Strategic Plan

15 Business Objective, Goal and Strategies Business Objective Process Goal Ensure systems function properly throughout their life A Maintenance Strategy is in Place Prior to Start-up Strategies Asset Record Creation Detailed condition monitoring from commissioning to end of life Defined Work Management Task (PM) Align contractual documents with asset records Defined Spare Parts Requirements

28 Lessons Learned Define what you are trying to accomplish. Understand what you are going to use the tool for. Have the end result in mind. You may need to adapt existing workflows to align with new strategies. Prioritize the effort based on organizational need.

29 Lessons Learned (contd.) Communicate, communicate, communicate o Develop a communication strategy and keep at it o Revise strategy as needed o Involve as many as possible Get the right people in the right roles as soon as possible Plan for initial and follow-up training Do not get discouraged when people push back

30 Next Steps 1. Develop Master Capital Plans with desired levels of service per watershed. 2. SAMPs for high risk asset classes 3. Leverage data and tools to make better business decisions. 4. Goes without saying Continuous Improvement!
