It failed because nobody's been allowed to clean up in three years.
Here's what actually happens in a 5-year-old Org: someone needs a small change. They're scared to touch the existing automation, so they add a new piece next to it. Multiply that by 200 changes and 4 Admins who've come and gone.
Now every deployment runs through a maze nobody fully understands. Half fail the first time. The team stops trusting the pipeline. “Quick changes” take two weeks.
That's not an Admin problem. It's a tech debt problem, and it compounds silently until someone finally measures it.
The fix isn't a re-implementation. You don't rip anything out. You refactor what's there: consolidate the automation, clean the dead weight, and deployments quietly start working again.
If your team has quietly accepted that failed deploys are “just how it is”: they're not. That's the most expensive sentence in Salesforce.
