I really like this model of technical debt. https://technology.riotgames.com/news/taxonomy-tech-debt https://technology.riotgames.com/news/taxonomy-tech-debt It breaks it down along three axis: * Impact. How much it affects things. * Fix cost. How hard is it to fix. * Contagion. How much it spreads over time.
