Ce travail introduit deux nouvelles variables susceptibles d'expliquer l'efficacité des champions d'un projet d'innovation technologique : l'ancienneté et le niveau hiérarchique. Cette recherche s'appuie sur un échantillon de 121 innovations technologiques commercialisées. Les résultats montrent que le niveau hiérarchique des champions est positivement associé aux projets d'innovation coûteux et que l'ancienneté des champions est positivement associée aux projets les plus innovants. De même, les résultats semblent indiquer que l'ancienneté des champions constitue un facteur clé de succès des innovations alors que le niveau hiérarchique apparaît sans effet.
