3. Design Studio II: Overall Goal
André is currently in Japan, where at the restaurant in the hotel, the servers carry with them little touch screen special devices on which they enter each order
The order is relayed to the kitchen, where the food is prepared, and to the cashier’s register, where a cumulative bill is kept until it is paid (cash, credit card, or as room charges)
Design the software that runs this system
do not worry about the user interface
focus on the back-end database and architecture

4. Design Studio II: Design Consideration
At one level, this means designing at the application level, such as how the hand-held device is ultimately used, where and when its contents is updated, etc.
usage scenarios
On the other hand, this means designing at the architecture level to decide upon the actual workings of the device software
high-level components and their interactions
responsibilities of the components
paraphrased: “What data goes where, and what rules and approaches govern how it flies around?”
You only need to document the architecture, but you can use elements from application design to motivate your architecture

5. Design Studio II: Two Problem Considerations
Note that the hotel has multiple restaurants, with different menus that change daily
Note that the idea is to sell the software not only to this hotel, but to other hotels that may have somewhat different settings

6. Design Studio II: As Always…
…articulate the stakeholders (do think broader than just the server and the cook)
…articulate the goals for the system
…diversify your initial solutions
…carefully consider the stakeholders’ anticipated experiences
…carefully consider the tradeoffs you make in your final design

7. Design Studio II: Schedule
Thursday November 19
bring a poster to class consisting of 8 slides
2 with content of your choosing
6 organized as 3 pairs
1 slide: alternative preliminary design
1 slide: its strengths/weaknesses
the slides should be sufficiently informative for others to comment on them without you explaining them
Tuesday November 24
bring a final design document
This is an individual assignment

8. Design Studio II: Your Design History
Using the template provided (see web site), keep track of the major decisions that you make over the course of this project, and how those decisions relate to each other
Hand this in together with the final design
