Procedural task analysis
Also known as: Task decomposition, Step-by-step analysis
A method of breaking down complex tasks into sequential, discrete steps to understand user workflows and identify points of difficulty. In accessibility contexts, procedural task analysis reveals where users with cognitive, sensory, or motor impairments encounter barriers — such as implicit assumptions in instructions, ambiguous terminology, or steps requiring fine motor precision — enabling designers to create more accessible procedures and documentation.
