Running a User DayThe Usability Round TableThe Usability Round Table is a separate focus-group-like discussion at the end of the parallel testing phase. Users have the opportunity to exchange their experiences and have a chance to discuss with the development team their concerns and needs. For the development team this is a great chance to establish a first consolidated list of the major issues revealed in the User Day. IntroductionThe Usability Round Table collects users' impressions of the application. It can be applied to all testing methods that are performed in parallel sessions in one User Day with multiple users. Typically the Usability Round Table takes up the last onbe to two hours of the User Day and users share their experiences of the software application with the development team. The moderator of the Usability Round Table draws up a plus-minus list for the tested application. The entries on the minus side are discussed in detail and suggestions are collected as to how these points can be avoided or corrected. At the end, the users can optionally fill out questionnaires on the application tested and about the User Day method in general. Participants and RolesTo avoid giving the users the inhibiting feeling of being watched, the discussion group should not be too large. Therefore the users and moderators should outnumber any other participants. With the recommended number of six users, one to two moderators, and about three to four members of the development team, there should not be more than ten to twelve participants. Developers should mainly be passive observers. Their task is to help the moderator if application-specific questions come up. UsersThe users report their findings about the application being tested and make contributions to the discussion. ModeratorA moderator supervises the Usability Round Table and leads the discussion. You can also have a pair of moderators instead, in which case they also share the task of keeping the log (see Logger). The moderator initiates the discussion with his or her questions and is responsible for documenting the contributions to the discussion in a comprehensible form and language so that developers who are not participating can understand them. A usability coordinator is suitable for this role since both expertise in user-integrated procedures and knowledge of the application and its context are combined here in one person. Training in moderation techniques is recommended. LoggerThis person writes down keywords from the discussion. For example, the reasons for and explanations of the user contributions are important since they are not recorded on post-it notes or cards and are only mentioned in the conversation with the participants. The log can be used to inform interested persons and members of the development group not taking part in the discussion about the contents and results. Important detailed information contained in the conversation should also be recorded for use in the design revision. For example, a user rejects the planned use of a drop-down list box for a field because too many entries appear. Until receiving this information, the developers might assume that not more than ten entries would be necessary at a company. DevelopersThe developers take a passive part in the discussion. The developers themselves do not make any contributions to the discussion, but are available for consultation. If a developer does not understand the user's contribution to the discussion, he or she asks questions for his or her own understanding. He or she may not comment on the user's statements, on the functionality, or on the design of the user interface in future versions of the application you are testing. Other StakeholdersPeople outside the development team with an interest in the results of the User Day can participate in this discussion. Typically, documentation writers, quality managers or sales and marketing people might be involved. They act in the same manner as the developers. Objectives of Usability Round TableThe discussion has the following objectives:
The discussion does not have the following objectives:
Resources Required
ScheduleOne to three hours are needed for the discussion; Typically this begins in the afternoon when the users and other participants return from the lunch break. It is also possible to schedule parallel test sessions and subsequent Round Table in half a day. IntroductionIn this phase, the moderator explains the general course of the discussion, the objectives, and the desired results. The participants also introduce themselves if required.
Creating the Plus-Minus ListThe plus-minus list is used to structure the discussion. The procedure is extremely simple for both the moderator and the users and helps to structure the Round Table. The moderator lists all the positive and negative aspects expressed by the users on the flipcharts. You should allow 15-20 minutes for this. The moderator should first collect all positive aspects experienced in the test sessions. Although you may switch between positive and negative aspects, it is usually hard to return on positive aspects once you start to discuss negative aspects. If collection of positive aspects slows down you may move on by collecting negative aspects. The negative aspects are the starting point for a discussion of the solution in the next phase. Consequently, you should clearly separate the collection of negative points and the discussion about possible solutions. The moderator points out to the users that ugly and uncomfortable aspects are also negative aspects that would otherwise be considered to be unimportant. The objective is to gather as many aspects as possible in the plus-minus list. Quantity has priority over quality or (apparent) irrelevance of a user experience. By asking appropriate starter questions the moderator has the control and responsibility to influence the collection of plus/minus points into a direction which fits to the focus of the User Day. The moderator can stimulate the feedback by asking prepared questions that focus on concept, structure, functionality, and user interface detail of the product. You may also use the terms of ISO 90421 Part 10 to structure the discussion. It is a good idea to hand out those questions as general focus questions prior to the test sessions to encourage the test user to focus on such problems. To support the authenticity of individual opinion against group dynamics, you may also ask users to write down their personal plus/minus list first on a paper before collecting those points all together. Finally, you should take care to check and log how many users agree with this point. Discuss Negative Aspects and Brainstorm Possible SolutionsIf there are a lot of negative aspects, you should prioritize them, i.e. each user should mark the two aspects that he or she considers most important. You can then deal with the aspects according to the number of times they are marked. The discussion should result in a consolidated and comprehensive problem statement for each negative point so that interested persons who are not participating in the User Day can read about the discussion and use the results. Adhere to the general rules for collecting feedback, i.e. the users' remarks should not be commented upon and developers should only ask comprehension questions.
Summarizing and Saying GoodbyeThe summary gives the users a final opportunity to comment of the application.
Additional Phase (Optional)After the User Day is finished, many development teams use the time to enhance the user's experience of the application. For example, the development group can present planned new developments or this phase can also be used to ask the users what they thought of the User Day. Further marketing and sales aspects can also be included here, for example special presentations, a product-related questionnaire or an overall evaluation of the user interface.
