L’engagement du consultant et son optimisme sont déterminants pour que cette alchimie fonctionne. C’est pourquoi, les Colettes sont persuadé(e)s que pour garantir l’enthousiasme et la motivation de chacun, les consultants doivent rester eux-mêmes et devenir une entreprise dans l’entreprise ! Chaque Colette est donc une entrepreneuse ou un entrepreneur ! Convainquant, non ?
