You're doing the work of a higher order function there. You have my thanks.
I've worked in environments where this type of change has been attempted. It's not easy and does run the risk of running VERY awry.
In another observed case, well, the process did seem to shine a light on people who's primary duties at work were to make sure they still had a job... In that scenario it can get really ugly because the optics make it look like "We empowered IT and things got worse!" Of course ignoring how the gatekeepers would rather quietly ruin projects before giving another division a 'win'. Leads to a huge fear culture because you start to ask who's going to be the next sacrifice for the lack of real progress on anything.
If you have some content or thinking you'd like to share, it would be appreciated!
So my work in "Digital Transformation" is a two part challenge of teaching management to think of their IT department as a source of creative energy and not bricklayers, while trying to get the engineers out of the mindset of bricklayers themselves after many years of being shoehorned. It is not easy.
