The document discusses an experiment conducted by a team at Roche to develop a new metric called the Net Manager Promoter Score (NMPS) to measure leadership. The NMPS is based on the well-known Net Promoter Score marketing metric, asking employees "Would you recommend your manager to others as a good boss to work for?". The goal is to use a simple, standardized question to promote continuous improvement in leadership and employee engagement across cultures. The global team conducting the experiment received support from senior sponsors to test whether the NMPS could provide a meaningful measure of an organization's leadership culture.
