User Experience Re-Mastered Your Guide to Getting the Right Design- P7: Good user interface design isnt just about aesthetics or using the latest technology. Designers also need to ensure their product is offering an optimal user experience. This requires user needs analysis, usability testing, persona creation, prototyping, design sketching, and evaluation through-out the design and development process.

User Experience Re-Mastered Your Guide to Getting the Right Design- P7 286 User Experience Re-Mastered: Your Guide to Getting the Right Design THE PILOT TEST Before any actual evaluation sessions are conducted, you should run a pilot test as a way of evaluating your evaluation session and to help ensure that it will work. It is a process of debugging or testing the evaluation material, the planned time schedule, the suitability of the task descriptions, and the running of the session. Participants for Your Pilot Test You can choose a participant for your pilot test in the same way as for your actual evaluation. However, in the pilot test, it is less important that the participant is completely representative of your target user group and it is more important that you feel confident about practicing with him or her. Your aim in the pilot test is to make sure that all the details of the evaluation are in place. Design and Assemble the Test Environment Try to do your pilot test in the same place as your evaluation or in a place that is as similar as possible. Assemble all the items you need: ■ Computer equipment and prototype, or your paper prototype. Keep a note of the version you use. ■ Your evaluation script and other materials. ■ Any other props or artifacts you need, such as paper and pens for the participants. ■ The incentives, if you are offering any. ■ If you are using video or other recording equipment, then make sure that you practice assembling it all for the pilot test. As you put it together, make a list of each item. There is nothing more aggravating than forgetting some vital part of your equipment. Run the Pilot Test Run the pilot participant through the evaluation procedure and all the support- ing materials. The session should be conducted in the same way as the actual evaluation session. Ideally, the evaluator(s) who will conduct the actual evalua- tion session should participate in the pilot test. They should observe, take notes, and facilitate the pilot test, just as they would do in the actual session. For example, they should consider the following questions: ■ Is the prototype functioning as required for the session? ■ Is the introductory material clear enough to the evaluator(s) and the participants? ■ Are the observation and data collection procedures working? ■ Are the evaluator(s) aware of their roles and responsibilities for the evaluation session? ■ Can the task descriptions be accomplished within the planned session time?Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Final Preparations for the Evaluation CHAPTER 9 287 While observing the pilot participant, make a note of where the evaluation materials and procedures may need to be improved before conducting the actual usability evaluation sessions. It is often helpful to analyze and interpret the data that you get from the pilot test. This often points out that an important facet of the evaluation has been overlooked and that some essential data, which you need to validate certain usability requirements, has not been collected. If you are short of time, then you might consider skipping the pilot test. If you do omit the pilot test, then you will find that you forget to design some details of the tasks or examples, discover that some item of equipment is miss- ing, realize that your interview plan omits a topic of great importance to the participants, or find that your prototype does not work as you had intended. Doing a pilot test is much simpler than trying to get all these details correct for your first participant. Often, the pilot test itself reveals many problems in the user interface (UI).
