Which method for constructing and validating a task analysis involves performing the skill yourself and recording each step as you go?

• A. Self-performance task-analysis
• B. Desk review of procedures
• C. Interview-based task-analysis
• D. Observation-based task-analysis

Answer: (A)

Performing the skill yourself and recording each step as you go is a self-performance task-analysis. This approach gives you firsthand, experiential insight into the exact sequence, timing, and decision points involved in the task, capturing nuances that might be missed if you rely on reports or secondhand observations. By actively doing the task, you validate the steps through your own experience, ensuring the documented procedure reflects real practice and not just what someone recalled or described.

Desk reviews rely on existing written procedures, which may omit subtle, tacit steps. Interview-based methods depend on memory and verbal report, which can introduce omissions or inaccuracies. Observation-based task-analysis involves watching someone else perform the task, which can reveal issues or variations but may still miss internal decision-making cues and minor steps you would catch by doing the task yourself.
