When building a system, we must ensure it works exactly as intended. But how can we be confident about that? This is where requirements verification and validation come into play. Although they may sound similar, each serves a distinct purpose. Verification checks if we built the system right, while validation ensures we built the right system. Understanding their differences helps reduce costly errors, save time, and deliver products that meet real user expectations.

I’ve often seen teams struggle with requirements verification and validation. Many confuse these two concepts, leading to misunderstandings and misaligned expectations. This confusion often causes communication gaps and project delays. However, when teams clearly define and apply both processes, they can detect errors early, avoid costly rework, and deliver better outcomes. In this article, I’ll break down what each process means and how they work together to ensure project success.

When developing systems, requirements validation is absolutely crucial. I cannot stress this enough. Without it, we risk building solutions that disappoint stakeholders and fail to meet real needs. Even worse, we might waste valuable time and money fixing issues that proper validation could have prevented. In this article, I’ll highlight why validating requirements early ensures quality, alignment, and long-term project success.
