The title of chapter 3 was a bit jarring the first time I read it. "Ignore the User, Know the Situation." Ignore the user? This seems to directly contradict what we've been learning in class. But after reading the chapter, Hoekman's point made a lot of sense to me. You're not ignoring the user, really. You're just ignoring the things about the user that you don't really need to know and instead focusing on what you do know: the context in which the user will be using the design. Hoekman calls this "activity-centered design" (ACD).
His reasoning for this approach is simple: sometimes the user base is broad, and focusing on a specific persona or personas actually limits the designer's ability to meet the needs of all of the users. However, more often than not, the situation in which the product will be used is something that they all will have in common. People adapt to technology. Although we absolutely should not discard all of the things we have learned about fitting the user's mental models and such, this means that it is in fact possible to effectively design things for the user without knowing all of the personal details that comprise a persona. This is the larger user-centered focus that Hoekman advocates.
Following this logic, and the idea that the user can adapt, I believe Hoekman would argue that the user isn't always right, and that features that users request aren't always the best. I certainly think they should be considered, but the idea behind situation-centered design is that you are designing for a large number of people with diverse backgrounds that are seeking to accomplish the same task. Because of this, making changes for a specific user group would put you in the same place that designing using a persona would. Before such changes should be made, it must be determined whether or not the changes would be helpful for all user groups to accomplish the task.
My partner and I got an early start for project 2, and actually had it completed before we discussed personas in any depth in class. Because of this, we actually did take a rather situation-centered approach. Our focus was on the needs of the user before starting a workout, while working out, and after completing a work out. The main distinction we drew was what makes a task easier to accomplish when the user is standing still on the treadmill, and what makes a task easier to accomplish when a user is running on the treadmill. We found those to be different, and it affected the way we did our design. In this way, I believe our approach was situation-centered.
