What is the sequence for B2B 7 figure deals? (Enterprise software)

Hi, I'm looking to learn more about the process to close an enterprise deal. Specifically, how many calls it takes to go from first discovery all the way through to close.

If you could share your experiences and format what ea call I used for, that'd be really helpful for me to understand and pick up on similarities across comments.

like

meeting 1 - discovery

meeting 2 - discuss partnership

meeting 3 - ??

meeting 4 - ??

Also, when you make your initial contact how do you bring in the other decision makers involved ? Say the person you speak with in meeting 1 says two other colleagues would have to be involved in the decision.

Are you expected to now do a meeting 1 with them now or can they join meeting 2 alongside the original prospect? How do you get person 2 and person 3 up to speed without having to do the same introductory discovery call with them too?

or is it standard process to repeat the call with everyone who is a decision maker?
