I have been working in the identity industry for over 10 years. It was not until the IDESG – NSTIC plenary that some folks said they were working on a functional model that I heard the term. I as per is normal for me pipped up and asked “what is a functional model”, people looked at me, looked back at the room and just kept going, ignoring my question. I have continued to ask it and on one has answered it.
I will state it out loud here again –
Functional Model
Quote: “A function model or functional model in systems engineering and software engineering is a structured representation of the functions (activities, actions, processes, operations) within the modeled system or subject area.”
That said, I believe that the question is useful from a rhetorical perspective. I’ve lost track of the role and value of the functional model. I find your question useful, paticularly as a precursor to a couple of other questions.
Why are we creating a functional model?
What is the value of a functional model?
How will we use the functional model?
