What is technical debt?

Technical debt is a term used to describe the compromises made during software development to speed up product launch. These compromises may include shortcuts in the code, features implemented on a temporary basis, or less optimal solutions. Like financial debt, these choices save time in the short term, but they generate "interest" in the form of extra work to correct problems later.

Imagine borrowing money to complete a project quickly. This loan allows you to move ahead immediately, but you then have to repay the sum with interest. Technical debt works the same way: the more compromises you accumulate, the more expensive it becomes to maintain and improve the software over time. If not carefully managed, technical debt can slow down product evolution, increase maintenance costs and even compromise overall software quality.

However, technical debt is not always negative. When used strategically and consciously, it can enable you to respond rapidly to market needs or validate hypotheses. The important thing is to understand that this debt must be repaid, otherwise the software will become increasingly difficult to manage.

In conclusion, technical debt is a powerful tool, but as with any debt, it's essential to know when and how to use it, while carefully planning its repayment to ensure the longevity and efficiency of your software.
