Voici quelques exemples de problèmes liés aux "exigences instables, imprécises et incomplètes": compréhension incomplète ou erronée des exigences des parties prenantes, les exigences dérivées ne sont pas identifiées, les exigences ne sont pas formulées correctement, les exigences sont peut-être en conflit les unes avec les autres et les perceptions des parties prenantes sur la valeur ne sont pas claires. Badreau & Boulanger (2014) ajoutent que les principales causes d'échec du projet liées aux exigences sont les suivantes : les exigences sont incomplètes, les utilisateurs ne participent pas au projet, les attentes sont irréalistes et la gestion des exigences est inefficace lorsque les exigences changent au cours du projet, le thème "exigences instables, imprécises et incomplètes" occupe la deuxième place parmi les "thèmes de défis dans la gestion des programmes d'ingénierie, vol.9000, 2005.
