Leaders are a causal force — they cause things to happen that were not going to happen without their influence.
They are future oriented and they envision possibilities that are often discontinuous with the past. They are adept at innovating, articulating a vision, architecting strategies, and inspiring growth and development in others on behalf of the vision.
Leaders are rich in determination and unwavering in resourcefulness. Thus, every person in every role has the opportunity and responsibility to demonstrate leadership — to be fully engaged and to perform beyond their day-to-day management responsibilities.
Both leadership AND management are needed
Managers attend to operational excellence and, at their best, deliver against expectations. Managers provide the business and its stakeholders with reliability, certainty, and predictability, all of which are essential to the viability and longevity of the organization.
