Pour éviter un rendu générique, nourrissez chaque variable avec des chiffres et contextes réels issus d’un entretien préalable avec le client. Ajoutez une section « Objections levées » listant les freins du décideur (budget, risque, délai) et comment ils ont été dépassés. Scindez la génération : lancez le prompt une fois pour la stratégie, puis une seconde pour les résultats, afin de mieux contrôler la cohérence des données.
