Business Challenges at PWD

1. Leveraging the PI Investment Does it serve a purpose?

Would anyone care if the PI was shutdown?

2. Measuring the Success Numerous Examples of Success, but it is tough to

measure their savings directly.

Is it possible to measure the ROI of an email service or a telephone system? Can a business survive without them?


Leveraging the PI InvestmentLeveraging the PI Investment - Rolling Out the PI System

• Data Source Closest To Users

– Reliability is Needed

– Contingencies Needed for Unreliable Data Links

• SCADA Reliability is Important for PI Data Reliability

• Garbage In = Garbage Out

• Need a Minimum of 6 mo. Of data to be of value to users

• It is easy to keep years of data accessible to users due to PI’s data compression and big hard drives


Leveraging the PI InvestmentLeveraging the PI Investment - Affect - Affect AllAll Levels of Personnel Levels of Personnel• Easy to get Managers and Technical
