- All tasks are performed at a computer. Users may be distracted or multitasking.
- Users may be constrained on time, or will easily see the service as a hassle if it takes more than a few minutes per day to use. The tasks, especially daily ones, should take as little time as possible.
...
- The Groups aspect of the site may be dropped if time gets too tight.
Justifications
This Task Analysis reflects our interviews and observations of people in different dining situations at MIT. We interviewed a student who lived in Burton-Conner (BC), a dorm with no dining plan; a student who lived at pika, an MIT independent living group with a house-run, required meal plan; several students at the MIT Alpha Delta Phi fraternity (ADP), ranging from those who cooked very little to the most active cook in the fraternity; and two students who lived in Ashdown House, a dorm with both a required dining plan (dinner only) and plenty of individual kitchens.
Originally, our plan was to create a site that helped students eat healthier by creating a site where students could find other students with similar tastes in food and organize cooking teams. However, the student at BC expressed discomfort with cooking with strangers and possibly even acquaintances, and said that scheduling would be a big problem for MIT students. The most active cook at ADP expressed similar concerns, saying that the people he might potentially cook with would be people he sees day-to-day anyway, and he doesn’t need a website to connect with them. Furthermore, as the student at pika showed, some students are already on mandatory dining plans that can cover all three meals of the day, and thus have pre-determined cooking groups. Many students also buy lunch on campus (e.g. from the Stata Center, Cafe Four, or food trucks) and live in dorms that require a dinner meal plan, meaning they have less of a need to cook. In fact, with the proposed changes to MIT dining, starting next year, some students may be eating all their meals at a dining hall. In addition, the students at Ashdown (one cooks dinner a few times per week and eats at the dining hall the other nights, while the other cooks dinner on most nights) pointed out that they wouldn’t use the site very much (on the order of twice a month) since cooking in groups usually takes more time than cooking by themselves.
