Task Decomposition

Why Task Decomposition is Important in User Research

Task decomposition is crucial in user research as it allows researchers to gain a deeper understanding of user behavior and thought processes. By breaking down complex tasks into smaller components, researchers can:

1. Identify pain points and areas of friction in user workflows
2. Uncover opportunities for design improvements and optimization
3. Create more accurate user journey maps and task flows
4. Develop more effective usability testing scenarios

How to Perform Task Decomposition

To effectively decompose tasks in user research:

1. Start with a high-level task or goal
2. Break it down into smaller subtasks or steps
3. Continue breaking down subtasks until you reach atomic actions
4. Analyze the relationships between subtasks
5. Validate the decomposition with users or subject matter experts

Examples of Task Decomposition in User Research

1. Online Shopping:

   • High-level task: Purchase a product online
   • Subtasks:
     • Search for the product
     • Compare options
     • Add to cart
     • Enter shipping information
     • Enter payment details
     • Confirm order

2. Mobile Banking:

   • High-level task: Transfer money between accounts
   • Subtasks:
     • Log in to the app
     • Navigate to transfer section
     • Select source account
     • Select destination account
     • Enter transfer amount
     • Review and confirm transfer

Frequently Asked Questions

• What are the benefits of task decomposition in user research?: Task decomposition helps identify user pain points, streamline workflows, and create more effective usability testing scenarios.

• How detailed should task decomposition be?: The level of detail depends on the research goals, but generally, tasks should be broken down to atomic actions that cannot be further divided.

• Can task decomposition be used in conjunction with other user research methods?: Yes, task decomposition can be combined with methods like user interviews, usability testing, and journey mapping for more comprehensive insights.

• How does task decomposition contribute to better user experience design?: By understanding the nuances of user tasks, designers can create more intuitive interfaces and streamlined processes that align with users' mental models and expectations.
