"What is being done, is what is being rewarded." If this is true, then all of our behaviors have some kind of reward attached. In most cases that reward is the comfort of pattern, i.e. we've always done it that way and see no reason why we should change - it is comfortable - it is a rut. Now being in a rut is not always a bad thing. Have you ever tried to change how you brush your teeth? Try switching to the opposite hand to hold and brush your teeth and you will experience in a small way the challenge of change, and the comfort of a rut.
As a leader, identifying the ruts which are conducive to accomplishing the mission, and those which are not, is part of the job. Someone has said that efficiency is doing things right and effectiveness is doing the right things. In other words, you can be doing things right, but those things may not contribute toward the fulfillment of the mission. The old forest and trees syndrome. Too many times the leader becomes focused on the trees and forgets the bigger picture . . . and then wonders why the mission never seems to get accomplished, even though huge amounts of time and energy are being poured out.
The benefit of understanding the GMP at the level of leadership is to see which behaviors are effective, i.e. "right" in the sense of mission fulfillment. Once behaviors or ministries are identified as being "off-track," the leader can strategize what the correct behavior needs to be AND THEN HOW TO PUT REWARDS INTO PLACE TO MOVE TOWARD THAT NEW BEHAVIOR.
This can and should include the process described in earlier posts regarding change principles - yet those principles, when augmented with this understanding have an even greater chance of success. Leaders have to be big picture people.
