Hierarchical Task Analysis
Hierarchical Task Analysis is a way to break s bigger task into smaller sub-tasks and make a hierarchy and solve them one by one to reach the final step and solve the main problem. It is mainly used in the field of design and Human Computer Interaction (HCI) to describe, analyze and understand the approach taken by users to solve a big and complex problem.
Some of the Key Features of HTA includes:
- Hierarchy: Complex and big problems are divided into smaller sub-problems, which are then organized into a hierarchical manner, so that user can add the solution of each sub-problem to solve the real big and complex problem.
- Decomposition: Each main task is divided into smaller sub-tasks, and each sub-task is then solved one by one, this approach gives a clear understanding about how a task can be solved or has been executed.
- Sequential Flow: hierarchical Task Analysis captures the sequential flow of the task execution, it shows the flow in which the problem was solved.
- Visualization: Hierarchical Task Analysis often represent the flow in charts of graph format, which makes it easier to understand the execution flow of the problem.
- User-Centric: Hierarchical Task Analysis is performed from a user’s perspective, means that how a user would react with the system, what would be their work flow to solve the problem etc.
Design Process & Task Analysis | HCI
Design Process is a systematic approach used by the designers to resolve complex issues or problems and deduce the solution. It is a structural method that helps designers to think, plan, and execute their ideas in real life to solve the complex problems given to them. In the rapidly changing world, design plays a key role in making any product or service to satisfy customers and meet their expectations. In this article, we will see some of the most important aspects of the Design Process and Task Analysis, and dig deep into the world of Design Methodologies, Task Analysis, Types of Task Analysis
