Leadership is about a sense of direction. The word 'lead' comes from an Anglo-Saxon word, common to north European languages, which means a road, a way, the path of a ship at sea. It is knowing what the next step is…
Managing is a different image. It is from the Latin 'Manus', a hand. It is handling a sword, a ship, a horse. It tends to be closely linked with the idea of machines. Managing had its origins in the 19th century with engineers and accountants coming in to run entrepreneurial outfits. They tended to think of them as systems.
But there are valuable ingredients in the concept of management that are not present in leadership. Managing is very strong on the idea of controlling, particularly financial control, and administration. Leaders are not necessarily good at administration or managing resources.
