The Expert operates entirely by intuition. He or she knows what their goal should be, what to do about it, and what should happen as a result. They’re emotionally involved and invested in the whole process, and since they’re running on intuition, they might have a hard time explaining why they do things to non-experts.
Context: Situational
They know what’s important and what isn’t, and can identify all the relevant pieces of the skill whether those are universal variables (car speed, piece value) or situational ones (road conditions, king position).
Perspective: Intuitive
The expert knows what’s important and what isn’t and what they should focus on entirely intuitively. They don’t need to choose what to focus on and don’t need rules for it, they just know what’s important for setting their goals and devising a method.
Decision Making: Intuitive
Whereas the first four levels of expertise still relied on analytical decision making by consciously deciding what the best course of action is, the expert intuitively knows what they should do and does it. They don’t need to explain the reasons, they can recognize it as they can recognize the face of a friend.
Engagement: Involved Goals, Choices, and Outcomes
Because the whole process is intuitive, the expert is emotionally invested in the outcomes of each part of the process. They emotionally feel the rightness or wrongness of their intuitions at the goal, action, and result stages, and can use that feedback to improve their intuitive decision making.
