1 Considerations:

The Process Analytics Community 1M$?

• Convene an Open Process Analytics “Forum”(Sponsored by CPAC or MCEC or ISA AD?)

• Develop a consensus about Proprietary vs Open Model (POM)(Learn from FF and OPCF?)

• Confirm challenges to achieve POM goals

• Establish a Workgroup to address each challenge(should NOT be a formal standardization effort)

• Issue Guidelines

• Keep Effort Evergreen

Opportunity is Knocking:

You are invited to an ad-hoc meeting on Tuesday 6:30 pm

Explore/Test Process Analytics “Forum” Concept:

• Connectivity (Plug and Play Integration)

• Modular Sampling System Initiative(More at our Sampling System Session this PM)
