Both are important-and rightly so. Who contributed, who was rewarded, and how the team was managed-someone must manage these aspects of any job. Most bosses want their staff members to follow their example. And since taking an ownership stance means looking out for the company as a whole, most bosses, if they are good ones, set good examples. Your behavior, like any boss's, is a reflection on the company.
Employees reflect how they are treated.
They will treat suppliers and customers the same way that they are treated. Again, for employees, this means putting the interests of the company before their own, and demonstrating the kind of behavior that accomplishes the task and maintains the company interests. And doing it over and over again. The real proof is in the results. Having a final goal, or a continuing set of sub-goals, is an important part of getting results.
