Editing Functional leadership model (section)

== History ==
In the 1970s, John Adair developed a model of Action-Centred Leadership comprising 3 interlocking balls in a venn diagram arrangement, labelled Task, Team and Individual on the premise that:
* the [[Task (project management)|Task]] can only be performed by the team and not by one person
* the [[Team]] can only achieve excellent task performance if all the individuals are fully developed
* the [[Individual]]s need the task to be challenged and motivated

Adair's model challenged [[trait theory]] by focusing on what leaders do. He showed that leadership could be taught and did not depend on a person's traits.
