The first assignment for the Software Development Processes course is a simple one. All you need to do is fill out a survey. This assignment is graded on completion, but more importantly, your responses are used to place you into groups for the projects, so please be sure to complete it by the deadline!
The survey can be found in the Instructor Notes of the final quiz of Lesson 1.
