Overly Complex Metrics
'The biggest mistake you should strive to avoid here is adding unnecessary complexity. The simpler a solution is, the less room there is for a costly mistake that could lead to a breach. This also makes it easier for new employees to be brought up to speed on managing your solutions, applications, and services.'

Micro-segmentation is scary
From my experience the truth is that simple segmentation and zoning is very hard in todays environments - people are struggling to separate PROD from DEV in anything but non trivial environments. let alone doing smth that is even close to micro.
The biggest mistake that people make, imho, is that they try to move from 0 to 100 and the comlexity vs. the marginal benefit over a much more modest segmentation goals is what kills the project, unfortunatelly for many years in an organization, once they fail it will take them a long time to try again. And frankly for most organizations it seams so "unachievable" that they do not even start doing it. 
My recommendation is to define modest goals such as separate prod from dev and select ~10-20 of you most cirital apps to ring-fence this achievable especially if leveraging the modern micro-segmentation technologies and you will be in a much much better place from your risk perspective.
