+  - 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
+  - perfection is not cost effective
+  - test early and often
+  - how to do
+    1. scenarios
+      - task analysis
+      - prototyping - partial
+        - use paper & pencil or simple tools
+    2. simplified thinking out loud
+      - use 3-6 real users
+      - ask user to think out loud while performing given tasks
+      - collect data by note-taking
+User-Centered Design (UCD)

+    - remember things in related groups
+    - have different ways of learning and communicating
+    - like to be in control
+  User Categories
+    1. The Novice User
+      - beginner or casual
+      - performance not a major concern
+      - don't rely on training or documentation
+    2. Intermediate User
+      - efficiency of routine tasks
+    3. Expert users
+      - 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
