Difference between Key Roles, Supporting Roles & Additional Roles?

Hi All,
I'm new to FDD. I would like to know what is the difference between Key Roles, Supporting Roles & Additional Roles in FDD? Further how do you determine which one role(actor) will go under which category (Key Roles/Suporting Roles/Additional Roles)?

No Such Formal Categories

Hi Ritin,

I've never published such formal categories of roles. Can you explain a bit more of what it is you'd like to know? 

There's a bunch of roles in FDD but I've never formally described them - nor cleaned them up. i.e. from the processes there are some roles that are not clear.
