Students will work in teams of four. Team work includes:

  1. Selecting an open source system: The system needs to be sufficiently complex, under active development, and open to external contributions.
  2. Writing four essays, covering
    1. the product vision, including required capabilities, roadmap, product context, and stakeholder analysis.
    2. architectural decisions made, including system decomposition, tradeoff points, as well as architectural styles and patterns adopted.
    3. an assessment of quality and (potential) technical debt; and
    4. a scalability study identifying possible scalability issues and proposing architectural changes to address them.
  3. Contributing changes to the open source system selected (via pull requests submitted on GitHub)
  4. Preparing a final video and presentation (and poster) summarizing the key results, and answering questions about it.
  5. Reviewing work from other teams, to learn from them, and to give them feedback

The four essays can build upon each other, but should be independently readable. We will collect all essays in an online book, that will emerge throughout the course. You can watch our progress (for essays made public) at the DESOSA 2022 site.


Each team is assigned a coach. The coach is there to help the team, answer questions, and give feedback on progress, the setup of the essays, and the contributions. Each team organizes two to three 30 minute sessions with the coach during weeks 3-7 of the course. For these sessions, the team prepares a short presentation on the current status and plans for the next weeks.

Mon Apr 4 17:00 Small improvements Pull request report Essay 3+4  

The “Small improvements” deadline offers an opportunity to make small fixes to your essay based on the reviewing comments. These changes are optional and should be small, i.e., at most 1-2 hours of work, and should focus on obvious mistakes and oversights. The “substance” of the essays should all be in the essays at the original deadline.


Students will receive grades based on the following:

The team grade is the weighted average of the team activities:

T = (3*E + C + P)/5

The individual grade then is the team grade to which a bonus can be added (or subtracted) for exceptional (top/bottom X%) results.

I = T + 0.5 * (R + A)
