In the agile development world, there is a temptation to prioritize speed over quality. After all, why write tests if I can deliver functionality faster?
The answer is simple: technical debt accumulates interest. Poorly written code today becomes bugs, delays, and frustrations tomorrow.
In our experience, teams that invest in code quality from the start end up delivering faster in the long run. The time "lost" writing tests and documentation is more than recovered.
The key is to find the right balance: do not over-engineer, but do not take shortcuts that compromise code maintainability either.
