Cоnsider the fоllоwing tаsk: invitees to а meeting need to be аble to quickly indicate whether they will or will not attend, and if not, they need to have the option to indicate a reason for their absence. Digital calendars need to provide mechanisms to support this task. Analyze this task from each of three models of the user: processor, predictor, and participant. First, analyze this task thinking of the user as a processor. Propose what the goal of the design should be given this view, and then propose how you might measure whether that goal was achieved. Remember, you should focus on the goal of the design, not the goal of the user. Then, analyze this task thinking of the user as a predictor. Again, propose what the goal of the design should be given this view, and then propose how you might measure whether that goal was achieved. Then, analyze this task thinking of the user as a participant. Again, propose what the goal of the design should be given this view, and then propose how you might measure whether that goal was achieved. Finally, discuss a way in which two different models of the user might suggest different design decisions. Identify one way the designs informed by the two models might differ, and propose how you would decide which design to go with. Note that there is no one single right answer to this question. There are many compatible goals and measurements you might propose. Our objective with this question is to evaluate whether the goals and measurements you propose are truly emblematic of the model to which you attach them. Focus your answer on efficiently demonstrating you understand the three models.
