Having identified the 4 key drivers with which to implement the corporate purpose (strategy, leadership, management systems and communication), we have defined concrete actions to deploy these drivers and increase the maturity level of the purpose implementation. This model is the result of a doctoral thesis in which we worked together with professionals belonging to the DPMC community of companies that had been activating the corporate purpose of their companies for at least three years. It was subsequently validated with a panel of academics, managers and consultants who are experts in corporate purpose and its activation.
