Notas del editor
- Iterative methodology that puts the user at the center of all design decisions. Optimize a user’s experience of a system, product, or process. Origin of UCD: Reaction to tools designed only for experts/engineers Based on human factors principles Designing with users at the center would have better usability and acceptance
- Personas may not be necessary. A bulleted list of basic user attributes can work just well. Research-driven creativity: it is not a black box magically converting raw information into design. The user research informs the prioritization and structure of the raw information. The user research also establishes the foundation of use cases for the design to support.
- Quantitative inventory A list of all existing content ID, Title/Topic, URL, Format, Metadata, Usage Statistics, Last Update Qualitative assessment Accuracy Usability Style Strategic goals Quantitative inventory: what content exists today and what shape it is in. A web content audit is an accounting of the content your organization currently has online. With content audit, you can anticipate problems before they arise, and avoid derailing your project. Qualitative audit: best practices assessment: A comparison of your content against industry best practices, usually done by a third-party, unbiased assessor. Qualitative audit: strategic assessment: An invaluable, in-depth look at how your content measures up to your strategic goals (business or user) A qualitative audit analyzes the quality and effectiveness of the content. Qualitative audit factors: usability, knowledge level (how much prior knowledge your user needs to understand your content), fundability, actionability, audience, accuracy For use in strategic assessments only: business value, message, brand/voice appropriateness
- Visual perception: Can users notice the prominent information Information hierarchy: Can users understand the priority of information Acceptance: Does the page work for users? Will they use it? Is the page cluttered? Task scenario: set up test tasks and ask users to come up with their own tasks User goals: Can the website meet user goals Workflow: Test navigation path, time, errors
