+  - a quick-and-dirty approach
+  - basic premise: designs change substantially in early development phases
+  - make a prototype that shows UI to get feedback early on

+    - like to be in control
+  User Categories

+      - beginner or casual
+      - performance not a major concern

+      - like to explore
+      - need keyboard shortcuts
+  Task Analysis
+    - to understand a business process
+    - identify what to support
+    - hierarchical task analysis (HTA)
+      - a top-down approach to task analysis and documentation
+    - task: a goal to achieve
+    - subtask: subgoals/actions
+    - atomic actions - are not broken down into sub-steps
+    - plans: sequences and conditions
+    - consider task frequencies
