• Collaboration that includes diverse backgrounds and perspectives can reflect the strengths of the individual team members.

Three students in different locations are collaborating on the development of an application. Which of the following strategies is LEAST likely to facilitate collaboration among the students?

• Having all three students participate in frequent video chat sessions to discuss ideas about the project and to provide feedback on work done so far

• Having all three students use an online shared folder to contribute and discuss components to be considered for use in the application

• Having all three students write code independently and then having one student combine the code into a program

• Having all three students work in a shared document that each can edit to provide comments on the work in progress

• Users can review the algorithms used in the software to help improve their efficiency.

• Users can provide documentation for program code at the end of the software development process.

• Users can provide feedback that can be used to incorporate a variety of perspectives into the software.

DineOutHelper is a mobile application that people can use to select a restaurant for a group meal. Each user creates a profile with a unique username and a list of food allergies or dietary restrictions. Each user can then build a contact list of other users of the app. A user who is organizing a meal with a group selects all the members of the group from the user’s contact list. The application then recommends one or more nearby restaurants based on whether the restaurant can accommodate all of the group members’ allergies and dietary restrictions. Suppose that Alejandra is using DineOutHelper to organize a meal with Brandon and Cynthia.

Which of the following data are needed for DineOutHelper to recommend a restaurant for the group? 1. Each group member's list of food allergies or dietary restrictions. 2. Alejandra's geographic location. 3. the usernames of the people on Brandon and Cynthia's contact list
