Objective: Identification and characterization of the target users, tasks and scenarios.

Description: This stage should include:

$$ User analysis: Identify the characteristics of the target user population. Multiple user classes

may exist, identify each one.

$$ Task analysis: Determine the tasks that should be allowed by your system and analyse their

characteristics. You should find and analyse $7$ high$-$level tasks. Each of these high$-$level

tasks should have a goal and subtasks.

$$ Scenario design: Create $3$ different scenarios $($a concrete example of tasks performed in a

hypothetical interface$)$ that include the tasks considered in the task analysis
