Ask HN: Name of a Problem dependent on a problem dependent on a problem etc?

The software I have made that is now heavily used within the business has not scaled well with the growth of the company. Due to the customer timely demands, Instead, of re-valuating and re-factoring the source I made tweaks, workarounds, etc to meet the requirements.

Now when a new change is required, I have fallen into a scenario that goes something like this.

Management: We now need your software to do X Me: OK, this means I need to change the way Y works first, but this can't be done until the way Z is modifed, but this relies on A

Malcome in the middle expresses this beautifully: https://www.youtube.com/watch?v=AbSehcT19u0

When trying to explain this, I usually end up tongue tied and the end of the conversation usually ends up like

Management: We need yout software to do X Me: OK, give me a few days

Is there a general name describing this effect?
