I presume this is shorthand for “technical debt,” part of the ridiculous Agile Newspeak that includes similarly imprecise terms like “refactoring” and outright insulting ones like “stories.”
Cutting corners to meet an unrealistic deadline imposed by bad managers always ends up costing more time than doing it right from the beginning. Like the guy who saved the time of issuing a database call by hard coding a snapshot of the table as an array of data structures. Need I mention his nationality? Nice work, champ. You met your deadline.
“Technical debt.” Bullshit buzz. Sounds Very Intelligent but it’s nothing new, just bad communication since what it really means can be expressed in the more accurate and prosaic original: unfinished work.
Just do it right the first time and if your manager complains, go over his head.
