Hierarchical Task Analysis in User Experience

What is hierarchical task analysis (HTA)?

What are the goals of HTA? (Select all that apply)

HTA communicates detailed user interactions with the system.

What is an important step when applying HTA to user experience?

The goal of hierarchical task analysis is to produce a ______ of steps that must be completed in some high-level tasks.

Which of the following is a benefit of hierarchical task analysis?

What is the first step in constructing a hierarchical task analysis?

Hierarchical Task Analysis (HTA)

HTA is a method for analyzing tasks using a hierarchical structure.
HTA starts at a high-level goal and breaks down into sub-goals, creating a tree-like structure.
HTA helps understand tasks, processes, and user experience.
HTA describes an activity in terms of goals, subgoals, operations, and plans.

Applying HTA to User Experience

HTA requires a detailed understanding of users' tasks.
The steps to achieve this understanding are:
- Identify users' primary goals.
- Detail the steps users must perform to accomplish their goals.
- Optimize those procedures.

Benefits of HTA

HTA enables objective comparison of different approaches to the same problem.
HTA supports user experience design due to its framework for consistent approaches and common language.
HTA supports user experience design reuse by providing a deeper understanding of system workings at various levels of abstraction.

Steps in Constructing HTA

Setting Goals: Define the desired task outcome.
Identifying Constraints: Determine limitations and boundaries.
Calculating Criticality: Prioritize subtasks based on importance.
Ceasing Re-Description... : Refine the breakdown until individual user steps are understood.
Generating...: Create plans, diagrams, and documentation to illustrate the HTA.
