Elusive problem looking for a solution?

I probably should have done this sooner.

I had an incident at work where one of our admins forgot to renew a certificate but luckily this has happened often enough that we have a standard procedure to fix it. Knowing this, I started searching around Reddit, apparently, this is such a common issue to build a software solution around it, hell one poster even called it a rite of passage (fair fair, very fair)

But it sounds like such an easy problem to solve isn’t it? During my research on other people’s experiences, many solutions were proposed, from google calendar to excel, custom CRM software, and more. I see people make do with what they got to solve this problem. Also, the critical items that expire are not just certificates but also licenses and other renewals. Well, I was pumped, as an engineer, who believes in the UNIX philosophy of doing one thing well, I started prototyping a software platform specifically for tracking expiration. But, this is NOT what I should have done, I should have talked to users first.

Considering I have zero product instinct, I am sure I am building the wrong thing. So let me ask the general public, is this a problem worth solving? Have you yourself come across this issue during your career?
