If you are systematic and consistent in putting people development first on your priority list, your entire team will make the same commitment. Leading the creation of such a culture is not easy. You have to start with yourself, your direct reports and set the clear expectation that  they will cascade your attitude  and processes through  their teams. The real organizational cultural change occurs when it starts with the CEO  and filters through the entire organization. But the size of your team does not matter, nor does it matter if you do not have other leaders as direct reports. You can still initiate the process of developing your people. Keep in mind that  people will know when you are truly committed to this kind of culture change, so don’t waste time going through the motions if you’re not willing to see it through.
