It is a structured product development methodology that involves users throughout all stages of Web site development, in order to create a Web site that meets users needs” - Usability.Gov

  7. 7. How do we get there?1. Interviews and Observation2. Focus groups3. Questionnaires4. Card Sorting5. Usability testing (formative and summative)
  8. 8. How do we get there?Interviews and Observations The interview is a method for discovering facts and opinions held by potential users of the system being designed. It is usually done by one interviewer speaking to one informant at a time. Reports of interviews have to be carefully analyzed and targeted to ensure they make their impact. Otherwise the effort is wasted.

  9. 9. How do we get there?Focus Groups A Moderator facilitates a small group of 4 to 8 participants by demonstrating or showing them a product or concept. The participants are encouraged to freely give their honest opinions about the product, including suggestions to make it better.

  10. 10. How do we get there?Questionnaires A questionnaire is a research instrument consisting of a series of questions and other prompts for the purpose of gathering information from respondents.

  11. 11. How do we get there?Card Sorting Card sorting is a useful tool used to determine how end users categorize information. In the process users are provided with cards and asked to create groups and categorize information the way it makes sense to them. There are two methods open and closed card sort. In Open method the user is provided the freedom to create their own categories while in closed card sort the groups (categories) are predefined. The information acquired is then analyzed and helps in developing the information architecture.

  12. 12. How do we get there?Usability testing Usability testing is a technique used to evaluate a product by testing it on users. This can be seen as an irreplaceable usability practice, since it gives direct input on how real users use the system.
