Act with Prudence

No matter how comfortable a schedule looks at the beginning of an iteration, you can’t avoid being under pressure some of the time. If you find yourself having to choose between “doing it right” and “doing it quick” it is often appealing to “do it quick” on the understanding that you’ll come back and fix it later. When you make this promise to yourself, your team, and your customer, you mean it. But all too often the next iteration brings new problems and you become focused on them. This sort of deferred work is known as technical debt and it is not your friend. Specifically, Martin Fowler calls this deliberate technical debt in his taxonomy of technical debt, which should not be confused with inadvertent technical debt.

There are times when you must incur technical debt to meet a deadline or implement a thin slice of a feature. Try not to be in this position, but if the situation absolutely demands it, then go ahead. But (and this is a big BUT) you must track technical debt and pay it back quickly or things go rapidly downhill. As soon as you make the decision to compromise, write a task card or log it in your issue tracking system to ensure that it does not get forgotten.

Pay off technical debt as soon as possible. It would be imprudent to do otherwise.
