Emerging Business Conditions
Emerging Business Conditions http://www.colbertnation.com/ Source: http://www.colbertnation.com/the ‐ colbert ‐ report ‐ videos/425692/april ‐ 22 ‐ 2013/tiny ‐ triumphs ‐‐‐ infrastructure ‐‐‐ river ‐ pollution
Emerging Business Conditions • Increasingly stringent regulations • Aging infrastructure • Flood planning disconnected from water quality planning • Customer base not aware of all services provided • Changing Boards and Councils • Limited resources • Key employees are retiring • Renewed focus on accountability
Approach
What is Asset Management? • Clearly communicates – What we need & why we need it – Long term funding needs to sustain the services – Consequences & risks • Sound basis for prioritizing work • Transparent, balanced
Risk ‐ Based Planning Represents a New Focus OLD NEW • Budget based on last year Backward Forward • Based on asset risk scores and • Little knowledge of system Looking Looking cost risks • Projects determined as • High risk assets slotted for Reactive problems arise during the Proactive renewal before failure occurs year Risk or • Budget could be determined Budget • Do as many projects as Budget based on agreed risk targets for Constrained you can afford each year system Constrained Ignores Focused on • Money is spent but overall • High risk assets addressed first asset and risk may not have been risk • Budget may rise or fall to meet reduced much management risk targets system risks
What Is Failure? Desired Condition? Minimum Standard?
Levels of Service

What are my optimized management strategies? a. What needs to be done? b. When? c. Costs? 5. What do I need to do to fund it?

What Is The Risk Associated With My Assets? Business Risk Exposure (BRE) Analysis: • The most powerful element in asset management! • Not all asset are equal! • Used for prioritization of activities with limited funding Triple Bottom Line Condition, Consequences Reliability, Business of Failure Performance Risk Exposure Probability Consequence of Failure (PoF) of Failure (CoF) x PoF CoF = BRE
Triple Bottom Line for CoF • Balanced • Transparent • Recognizes all concerns • Doesn’t borrow from future generations

How to get started… 1. A basic inventory can give enough data to justify investment 2. Asset management should not operate remotely 3. Senior management understanding the concept is critical to success 4. Staff should be involved and included in developing the program and compiling data 5. Software does not need be complex 6. You can manage the program JUST GET STARTED
