|
Determine the goals |
- goals guide evaluation by helping to determine its scope, so identifying what these goals are is the first step in planning an evaluation |
|
|
Explore the questions |
- in order to make goals operational, we must clearly articulate the questions to be answered by the evaluation - questions can be broken down into very specific sub-questions to make the evaluation even more fine-grained |
|
|
Choose the approach and methods |
the evaluation approach influences the kinds of methods that are used - combinations of approaches and methods are often used to obtain different perspectives - each type of data tells the story from a different point of view - these perspectives give a broad picture of how well the design meets the usability and user experience goals |
|
|
Identify practical issues |
- some issues to be considered include access to appropriate users, facilities and equipment,whether schedules and budgets are realistic and whether the evaluators have the appropriate expertise to conduct the study - there may have to be compromises that involve adapting or substituting methods - suprise events may occur |
|
|
Decide how to deal with ethical issues |
- professional organisations provide ethical codes that expert members to uphold - all data gathering requires to consider ethical issues but especially evaluation as the participants are often put into unfamiliar situations. - people's privacy should be protected - personal records shoud be confidential - informed consent form |
|
|
guidelines for informed consent form |
- tell participants the goal of the study and what they should expect - explain that their sensitive information is confidential - make sure that they know that they free to stop anytime - decide whether it is appropriate to provide incentives such as food, book tokens or payment avoid including quotes and descriptions that provides clues from the person's identity - ask persons permission to quote them |
