Key points• No longer enough to run systems – need to

provide good data• Everyone has data problems• How we are trying to overcome our data

problems• Examples of data being put to good use


Data

More data utilized properly will help users and decision makers save energy and water

backups, redundancy

Quality Assurance/Control• One system of record• Commissioning/calibration

– Data accuracy– Equipment installation– Equipment maintenance

• Internal audits– Data quality– Point configuration (poling

frequency, data transformations)


Meta data – Context


Meta data – Process Flow Diagrams

System Utilization


Management of change• Systems to document changes to:

– Tags– Process flow– Data flow– Equipment inventory– Meta data– Data infrastructure

• Notification/communication of changes


Automation• Automatic transfer of meta data from system of record• Automatic updates to SOPs, data flow diagrams,

equipment inventory• Notifications and alarms for data management system

issues, data quality issues, and especially asset specific issues revealed by the metrics, analytics

• Automation allows data scientists to focus on the cool stuff


What you can do with a little good data


Key points• No longer enough to run systems – need to

provide good data• Everyone has data problems• How we are trying to overcome our data

problems• Examples of data being put to good use
