Know the rules
(Why is this important? Example 1
, Example 2)
Purposes of the Skill
- Pole Vault
(in mechanical terms)
We want to score an ace by putting the ball past the receiver or to gain an advantage by putting the receiver in a poor position to return the ball effectively.
In mechanical terms: Optimize speed, accuracy, and fluid dynamics of the ball.
Choose a skill: Write the purpose in mechanical terms and the characteristics of most effective technique

Forehand drive in tennis
- What will be the focus of the observation?
- Where is the best place to observe from?
- What is the skill level of the participant?
- How might the conditions affect performance?
- Identify errors
- Evaluate errors
- Is the performer at risk of injury? Pole Break
- How long will it take to correct the error(s)?
- How large of an effect does the error have on performance?
- Is the error due to technique issues or a lack of strength? Pole Vault
- Is the error due to inadequate or innapropriate equipment?
- Was the error due to something that occured earlier in the performance?Adam Nelson
Repeat the analysis
- Communicate with the performer
- Correct the error
