<p data-start=”83″ data-end=”321″>In software development, knowing the distinction between verification vs validation is crucial for ensuring quality at every stage. Both processes aim to detect defects, but they differ in focus and timing within the software lifecycle.</p>
<p data-start=”323″ data-end=”571″><strong data-start=”323″ data-end=”339″>Verification is a process-oriented approach. It ensures that the product is being built according to specifications and design documents. In other words, it answers the question: <em data-start=”506″ data-end=”542″>Are we building the product right? Common activities include:</p>

<ul data-start=”573″ data-end=”705″>
<li data-start=”573″ data-end=”625″>
<p data-start=”575″ data-end=”625″>Reviewing requirements and design specifications</p>

<li data-start=”626″ data-end=”663″>
<p data-start=”628″ data-end=”663″>Code inspections and walkthroughs</p>

<li data-start=”664″ data-end=”705″>
<p data-start=”666″ data-end=”705″>Static analysis and compliance checks</p>

Essentially, it answers: <em data-start=”858″ data-end=”894″>Are we building the right product? Common activities include:</p>

<ul data-start=”925″ data-end=”1024″>
<li data-start=”925″ data-end=”958″>
<p data-start=”927″ data-end=”958″>Functional and system testing</p>

<li data-start=”959″ data-end=”992″>
<p data-start=”961″ data-end=”992″>User acceptance testing (UAT)</p>

<li data-start=”993″ data-end=”1024″>
<p data-start=”995″ data-end=”1024″>Real-world scenario testing</p>

<p data-start=”1026″ data-end=”1308″ data-is-last-node=”” data-is-only-node=””>Both verification and validation are essential. Verification prevents defects early by checking correctness against requirements, while validation ensures the software actually solves the intended problem for users. Together, they provide a comprehensive quality assurance strategy.</p>
