What is technical debt?
The easiest explanation is that hardware, software, or technical processes you implement now may not work in the future. This can manifest in many ways. When you're under pressure to put something together quickly, this can result in bugs that will take a lot of time to fix (possibly more time than doing it correctly the first time). Technical debt can also manifest when you move information over from a legacy system, or it can be something that needs to be fixed with better documentation to help user adoption or ensure people use the tools correctly.
