Do any of you have experience with an outside sales consultant coming in to shake things up?

Hello everyone!

Recently my company hired an outsided sales consultant to run an audit of our entire sales process. They are coming in with a point to prove as they have been fierce in their feedback to everyone so far. During my conversation, I had to do a cold call in the spot with a discovery call, which was under intene scrutiny. (I am a BDR Manager)

The consultant made it clear that those that do not get on board with their plan, would be more or less let go. Does anyone have any experience with this? Is the process for these kinds of things always like this?

Side note, my company is a total sales mess. We have a nice pipeline but no real sales metrics and each region doing their own thing, so this audit is well needed.
