17. 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?
SE includes writing code, design patterns, program analysis, unit testing, code reviewing, etc…
Devs write the code. Design patterns help devs. Program analysis points out problems caused by a dev so that the dev can fix it.
Human design, implement, and test the software, and often use it too.
Too often the human side of things is completely ignored.

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

25. 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)

26. 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!

27. 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

28. 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

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