I think the biggest win for this job was not the six points identified, but the author gained their boss's trust; got project alignment to the organization's mission, and earned more autonomy.

In essence the task-oriented leading was switched to area-of-responsibility leading. That is, instead of giving a list of tasks to complete by the author, an AoR was given, and all tasks initially verified, then allowed to move forward as the author saw it fit. It is task-oriented vs. AoR-Oriented leadership.

Basically, in large part this worked because of the job context and the leadership of the boss.
