If you are the CTO of your organization what changes would you do?

I have been at my company for almost 5 years and the last year or so I have come to the understanding that most of the difficult to solve issues me and my team face actually originate from a few underlying massive issues and bad decisions my organisation took. It is difficult to solve these issues for good without a c-level influence.

For example it is difficult to find a source of truth of many information in my organisation at the moment. So one change I would do is introduce something like an ESB and appoint a staff or principle engineer to maintain it alongside a organisation wide schema.

I wonder if there are others in the tech sphere facing similar issues and would like to hear from them if so.
