Re: A wise man once told me......
Like all projects, this one will also go thru' The Emotional Cycle of Change (http://ow.ly/Vvdk30rumNp). Right now, it's at the "Uninformed Optimism" stage. By the end of 2020, it will have moved into the "Informed Pessimism" or "Valley of Despair" stages, when we'll really know about those savings!
On another note, the wise man who told you about LEAST BAD is totally right. And not just when it comes to selection exercises. Back in the day, I used to work for a leading IT company in India. We used to tell our customers proudly that our company was rated as the BEST IT company in India by a leading tech publication. Then one long-term customer corrected us by saying it was the LEAST BAD IT company in India! This also seems to be true outside the IT industry. Social media conversation shows that Bank of America is consumer's most favorite bank aka least disliked bank (https://twitter.com/NowYouKnowConf/status/976832880851718145).
