John, Great article and congratulations.
It will be cool if we can say:
I am my own system of record.
i.e. I own all the data about myself.
I am my own system of engagement.
i.e. I determine when and how I engage with my current supplier relationships.
I am my own system of discovery.
i.e. I determine when I need to discover new supplier relationships and attract the right suppliers to my orbit at that time.
In totality, the three vectors provide agency for the customer. But, it will need supply side systems and actors to play ball and actively participate. Which they will when there is enough pull.
regards
AJ
