Strategy in Greek (strategia) means the “art of the general,” and, since ancient times, implied the ability to achieve a complex battle goal. In the modern business world, common “battles” may include executing a digital transformation strategy, winning the war for talent, or disrupting yourself before others do so. Whichever it might be, the only valid strategy is one that can be executed. As Thomas Edison famously noted, “vision without implementation is just hallucination”.
