Task Analysis

INTRODUCTION

CORE DEFINITION
Task Analysis is the systematic decomposition of what a task demands, covering the sequence of steps, the knowledge and skill each step requires, the decision points with their criteria, and the stages where errors typically occur. Its core proposition is that effective training, interface, or automation design requires an explicit model of the task before any of those are built. The key qualifier is whose performance is modeled: an expert's account omits the difficulties a novice actually faces, so observation of real performers is required.
SCAFFOLDING EFFECT
Reduce cognitive load
- Step listing: write down the sequence of steps that a real performer actually goes through. - Decision marking: identify each point where a judgment is required and what criterion actually governs it. - Error mapping: record where performers commonly go wrong and understand exactly why they do.
Anchor fast decisions
Experts perform many steps automatically and therefore omit them when describing the task, so instruction built on their account has invisible gaps. Making the steps, criteria, and failure points explicit closes those gaps and lets designers target support at the points where it is actually needed. The task model becomes the shared reference for training, interface, and automation decisions.
