I’ve turned this on in our Sandbox environment a few months ago, but honestly couldn’t figure out how it worked.  I am wondering if this is one of the components of this product (like some of the community functions), that where hold overs from older versions.

@Thbutler - I’m wondering the same thing. I meant to ask my CSM this week when we met but forgot to so may reach out to them as well.  I’m not fully understanding how it works and is value add, so far. 

I have a meeting with my CSM at the end of the month.  We are about to begin our annual planning process (still would be nice if we could leverage Planning, but that is another conversation).  I wonder if it is something we could use.

I’d recommend using Experience Estimating over Functional Estimating.

You can use this to change project duration and/or effort, up and down, to quickly side a project based on a WBS template.
