You are the new Chief Design Officer (CDO) of a start-up, DTUI Inc. The project is to design a system for selling pottery. The aim is to develop an interface that meets the needs of both the potters and the customers. Describe in detail a design methodology of four stages to facilitate the proper design of such a system. Write your answer in the form of a management plan for this project. For each stage, indicate the number of weeks that should be allocated. Hint: Note the four phases of the design process: • Requirements analysis • Preliminary (conceptual) and detailed design • Build and implementation • Evaluation For questions 2–4, refer to the following scenario: The State of Maryland is developing a web-voting interface. For selecting the candidates, one design (RB) is a set of radio buttons and another is (CB) a combo-box (drops down when selecting the scroll arrow icon), both using standard fonts at 10-point size. 2. Compare these two designs when there are four candidates and predict the relative speed of performance and error rates. Support your choice by a thoughtful argument. 3. An expert reviewer complains that both designs may work with young users who are familiar and expert in using a mouse, but that there will be problems for elderly and motor-impaired users who have difficulty controlling a mouse. The reviewer recommends a new design that includes a larger font (20-point size) and a numbered list to allow selection by keyboard easily. Describe a participatory design or social impact statement process that might clarify this issue with elderly users. 4. Design an experiment to help resolve the issue brought up in question 3. Assume you have substantial resources and access to subjects. 5. What is user-centered design? What are its benefits? 6. Consider a system that does not yet exist; for example, a totally automated fast-food restaurant, where customers order via touch screen interactions, pay by swiping their debit or credit cards, and then pick up their food— analogous to the self-check-out at some supermarkets, but even more extreme. Discuss how you would conduct a contextual inquiry for a system that does not yet exist
