Task analysis ensures that the design is compatible with all the necessary tasks. It Identifies actions and cognitive processes required for a user to complete the task or achieve a specific goal.
Through task analysis we can learn from the goals of the users, what they are trying to achieve and ensure that the design is compatible with all tasks. A detailed analysis allows the identification and understanding of the structure, flow and the attributes of each task and through the decomposition of tasks into subtasks and their constitutive operations we can deliver relevant information to the process design.
We can identify the tasks that must be supported and refine the interface and include for example, through the steps of the user, a better navigation or search for your website or application. We can determine the appropriate scope of content and create websites and apps that meet specific objectives or tasks of users.
Task analysis also allows us to understand how users are influenced by their physical environment and how knowledge and previous experience of the users influences the thinking about their work and the workflow.
This type of analysis gives us relevant insights about how to design and assign tasks and to specify the characteristics of the interface. Task analysis can be vital to the maintenance of a system and for migrating a task to a a new system.
The results of a task analysis include a detailed description of the physical, perceptual and cognitive activities involved in each task and provide information about its duration and variability, the frequency of the task, the task sequence, tasks allocations, the complexity of the tasks, conditions of the physical environment, data and information dependencies and tools needed to complete the task.
