The people who use your products or services are not concerned with which department provided it or if there was a star player on the team. They are concerned with the quality of the product or service. It is the effort of the group that produces wins. When too much emphasis is placed on one star player, the other members of the team feel devalued and are less supportive. That star player may influence the result, but by himself he cannot create the wins. We see this in sports everyday.
Similarly, when units operate as silos within an organization, they create the "me and them" effect. The lack of communication and cooperation between the units fosters delays, mistrust, duplication of efforts, and misinterpretation of instructions, leading to a very unpleasant client experience. When members of a team or organization work in harmony, respecting and supporting each other, trust is built and results are multiplied.
What are you doing as a leader to break down the silos in your organization? How are you facilitating trust and cooperation? Are star players treated more favourably at the expense of other team players? How do you ensure that high performers are rewarded without diminishing the necessary and important role of the other team members?
