Pour renforcer la crédibilité, ajoutez au prompt l’exigence que chaque chiffre soit accompagné d’une base de comparaison (ex. « vs. même période l’an dernier ») et d’une durée de mesure. Demandez aussi un encadré « Méthodologie de mesure » détaillant les sources de données : cela rendra l’étude de cas nettement plus convaincante face à des dirigeants B2B.
