Execution not only ensures efficient use of resources in a credit and cash-starved world, but also provides the feedback loop needed for the business to adjust to changes—big or small—in the external world. True, leaders must still conceive of a path forward, but execution is what drives the organization along that path and allows it to seize opportunities. And good execution not only will see a company through the tough times, but also significantly improve its chances for success as the environment continues to shift.
