I've worked for a few Fortune 50 companies, and they all had "shadow IT" that would crank out scripts and tools with no official sanction to work around the cumbersomeness of the official tools (or sometimes their complete lack). That's what corporate hackers are.
My other half is one of those. Works in setting up hospital pharmacies for new hospitals and he's the "excel and VBA guy" to all his coworkers.
It's amazing how far just a little bit of programming can
You know your company has made it when shadow IT has been merged into central IT after a tough political fight, and as they try to make the old shadow IT less responsive and more standard, a new wave of real shadow IT gets hired. That new, real shadow IT might even be paid more, because they are often hidden in CapEx somewhere, instead of having to go with HR standards for leveling and job descriptions. I've seen the biggest things come out of said shadow IT groups, precisely because their management is uninterested in the glacial procedures of real IT.
