About

In this course, teams of 4-6 students work with real clients (generally nonprofits and campus units) to develop or enhance SaaS apps that support the work of that client, using the Agile practices learned in CS169A: lo-fi mockups of user stories, BDD & TDD with Cucumber and RSpec, pull-request-based code reviews, continuous integration, legacy code management, and so on.

Grading criteria are based almost entirely on project work and effectiveness of engaging with your client, including getting at least one (and hopefully more than one!) pull request incorporated into the "golden" (upstream) repo for each project.

Enrollment criteria

Since capacity is limited, to enroll you must (a) join the waitlist, and (b) fill out this 1-minute survey. Michael and Armando will make decisions before the start of classes. To join the waitlist and ultimately enroll, you must:

Be a registered CS major (EECS or L&S)
Have completed CS(w)169 or CS(w)169A with a B+ or better

Note that those are necessary conditions but they don’t guarantee you will get in, since space is limited. If you meet the above criteria but are still unable to join the waitlist, please email cs-enrollments@berkeley.edu for help.

Concurrent enrollment students, and students who have not taken the prerequisite courses: If you believe you have the necessary background to take CS169L without having taking CS169A, please contact the instructors and we will arrange for you to take a placement exam. The textbook for CS169A is open access and the course covers most of the book, with the heaviest emphasis on chapters 1-5 and 7-10. This exam will be administered in the Computer-Based Testing Facility on campus (not remotely, sorry) and there is no fixed passing score—the instructors will make a holistic evaluation based on your exam. If you have expressed interest in the course without meeting the prereqs and are interested in this option, but you have not received email from the instructors about how to proceed, please email us.

Format and attendance

Class meetings are in person and regular attendance is required to pass. If you are unable systematically to attend in person, please do not enroll.

There is no final exam but there may be short quizzes throughout the course, using PrairieLearn.
Teams of 5 or 6 will be formed by the course staff; we will let you designate at most one other enrolled student you'd like to make sure is on your team. We will not allow self-formed teams or ‘cliques’ larger than 2. We will explain our rationale during the first class meeting, but we will not respond to requests for exceptions since the answer is "no."
We are surveying real customers now, and each team will vote as a team on which customer they want to work with.
Class meetings will cover a variety of topics, depending on how projects are going:
- Brief reviews of Agile workflows/tools from CS169A
- "Clinics" where we critique/debug project design as a group
- Relevant guest speakers
- "Bootcamps" where we provide short intros to libraries, gems, technologies, etc. that might be needed by one or more projects
- Student team presentations of project progress

Workload

This is a 4-unit course, which theoretically represents 12 hours per week of work (including both in-class and out-of-class), and most students spend at least that much time on it.

Importantly, a main component of your out-of-class time will be customer meetings and team meetings, both technical and nontechnical. We will make available some scheduled class time for team work, but you need to have a sufficiently flexible schedule to be able to meet regularly with your team. If your schedule is packed and you're expecting team meetings to only occurs on nights and weekends, you might want to reconsider, since those meetings are an essential component of project progress on which grading is based.
