Implementing a software feature takes a certain amount of time, and time translates pretty directly to money. Sometimes, you may need to meet a deadline or run out of budget, so you end up implementing the feature at a lower quality or without completing the usual checks or constructing it in such a way that nothing else can be built on top.

This allows you to meet the time/money constraints, but it will come back to haunt you, either making the implementation of future features more costly, or requiring the mess you left behind to be cleaned up, before trying to build on top.
As such, it feels a lot like you’re taking up ‘technical debt’, which you’ll have to pay for later.
