Standards Committee Work

Draft ISA112 SCADA Systems Management Lifecycle Diagram

I enjoy working with experts in their field to develop, update and maintain published consensus-based standards documents. I find consensus-based standards work is very rewarding as you get the opportunity to share ideas and best practices with the top experts in their area of expertise.

Standards committee work is a long-term endeavour. It often takes 3-5 years (or more) to develop a good high-quality consensus-based technical standard or technical report. There are many benefits of using published standards. The main one is that by using published standards you can avoid having to do custom-design-work by using best practices that have been developed by strong committees of experts that has been subjected to a rigourous peer-review process.

Some of the technical committees I have contributed to over the years:

  • CSA P125: Operational Technology Functional Safety and Security, Voting Member - Canadian Standards Association
  • Standards and Practices Board, Director - International Society of Automation (ISA)
  • ISA112 SCADA Systems, Co-chair
  • ISA18 Alarm Management, Voting Member & Co-Managing Director
  • ISA101 HMI Design - Human Machine Interfaces, Voting Member
  • ISA99 Cybersecurity for Industrial Control Systems (committee that develop and maintain the ISA/IEC-62443 series of standards)
  • IEC TC65/65A/WG15: Industrial Process Measurement, Control and Automation - System Aspects - Management of Alarm Systems for the Process Industries - info - International Electrotechnical Commission
  • IEC TC65/65A/WG19: Industrial Process Measurement, Control and Automation - System Aspects - Human-Machine Interfaces for Process Automation Systems - info
  • SCC/IEC TC65/65A: Canadian Mirror Committee for IEC-TC65/65A: Industrial Process Measurement, Control and Automation - Standards Council of Canada
  • Enhanced Train Control (ETC) - Security Sub-Committee, Railway Association of Canada (RAC), (2022 - present)
  • Interoperable Train Control (ITC) - Security Sub-Committee, Association of American of Railroads (AAR), (2022 - present
  • ISA105 Automatic Control System Commissioning
  • AWWA Cybersecurity Sub-Committee - Amercian Water Works Association
