Selected Answer: B

Falacia de la ausencia de defectos. Es una falacia (es decir, un concepto erróneo) esperar que la verificación del software garantice el éxito de un sistema. Probar minuciosamente todos los requisitos especificados y corregir todos los defectos encontrados aún podría producir un sistema que no satisfaga las necesidades y expectativas de los usuarios, que no ayude a lograr los objetivos comerciales del cliente y que sea inferior en comparación con otros sistemas de la competencia. Además de la verificación, también se debe llevar a cabo la validación (Boehm 1981).
