44yo sysadmin...
Plenty experience I the telco and alarm/incident management.
The company I worked for was about to laid a lot of people. Talked with HR, negotiated a good package and became their beta tester.
Spent two years understanding the Why's and Don't from Big Data and Analytics.
Now as a senior cerified Google Cloud architect and certified Azure Data Scientist about to jump ship to service development...
Nowadays you don't need to go he management route if you don't want to, but you must take the commercial one instead (estimate times, effort, team needed, costs, margins, etc).
