What is Software Engineering? Software engineering is the application of a systematic, disciplined, quantifiable approach to the design, development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering to software. IEEE’s definition

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.

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

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.
