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

© Copyr igh t 2014 OSIsof t , LLC. 17

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
