Human-Centric Software Engineering • Devs are people! • All bugs are caused by people. – Flawed requirements – Flawed design – Flawed implementation • So… how do we solve humans?

Course Structure • Presentations • Participation • Project • No exams • Few lectures – How to evaluate dev tools? – How to comprehend a large codebase?

Participation • Class time is based around discussions • Everyone should contribute – You’ll be graded on it! • Discussions will be led a student • Occasional in-class activities – Competition: fix a small bug as fast as possible – Give feedback on each other’s project – May require some effort outside of class (install a tool)

Presentations • Everyone will regularly present • 10 -15 minutes • Demo a tool or present a paper • Each week will have a theme • You have some choice in what you present • Based on how many people enrolled… – 1 paper presentation and 2 tool demos • If you aren’t presenting… at least skim the papers!

Who and what gets presented? • Each Friday you can volunteer to present next week • I’ll decide the topic and papers • You can decide which tools to demo for the topic • I’ll provide templates

Example weeks • Monday: 2 paper presentations and discussions • Wed: 3 tool demos and discussions • Fri: 2 tool demos & decide who will present next week • Monday: lecture and activity • Wed: 3 tool demos and discussions • Fri: 2 tool demos & decide who will present next week

Project • Design, implement, and evaluate a dev tool • More details to come…

This course is your oyster • Have an interest in a topic? • Want to try an activity in-class? • Prepping for the job market? Let me know! I might fit it in. This class is meant to benefit you.
