“Producing a decided, decisive, or desired effect: impressive, striking: ready for service or action: actual: being in effect: operative. This is how Merriam- Webster defines the highly-sought adjective in today’s world, “effective.” Another dictionary defines it as “adequate to accomplish a purpose; producing the intended or expected result.” However, when this mighty adjective is put before “principal” or “school leader” it encompasses more than its explicit meaning in the dictionary.
“The intended or expected results” of business is to make money. Neither business nor leaders of such business would be called effective if there is no profit involved. One would not call his/her car “an effective way of transportation” if it is not moving, hence not serving its intended or expected result.
