Study Notes
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.
