Question

Soon I will need to give a presentation on my honours project for the engineering faculty and a large group of engineering and technology students at my university. While all the the people attending will be technical-minded, not all of them will be programmers and most will be from other engineering disciplines.

I have given presentations before, and I am confident speaking to a crowd, but I realize now all the presentations I have given before have been to fellow CS/SE majors and teaching staff. I wonder if my presentation style assumes that I am presenting to other software geeks, so they will know what I am talking about and I can put on a more interactive demo involving the audience.

My honours project isn’t terribly complex or theoretical, I have a prototype C# Winforms app but it is designed to be extensible and operate with different data sources (ODBC or WS) in the future, and some research to how it could be extended with a rule engine and DSL and turned into a marketable product. The organization that is testing my prototype is saving tens of thousands of dollars a year by automating a critical business function.

I had planned to show off how extensible it was by some live coding and UML-style diagrams. I really enjoy doing demos and live coding but I don’t know if that kind of presentation will be as accessible to non-programmers, and I am worried if I get too geeky and technical I may alienate the audience and judges.

What are the effective techniques you have found to present software projects in a way that is also interesting to non-programmers

Answer 1

When I was working on my doctorate, the faculty gave us this rule for seminars – and it has proved very useful since:

1. Tell ’em what you’re gonna tell ’em. (E.g., brief introductory problem
   description and results abstract)
2. Tell ’em. (E.g. technical details comprising the bulk of the time)
3. Tell ’em what you told ’em. (E.g. brief summary and conclusions)
4. Open the floor for questions.

In your position, I would take about 10-20% of your allotted time to do #1 in a largely non-technical way. So you might describe the business function your code automates, why that’s important, what things were like before and after applying your solution, how it’s saving money, that kind of thing.

Then I’d launch into a highly technical discussion aimed at the CS/SE crowd. Even if the rest of the folks don’t understand it and their eyes glaze over, your introduction at least will have given them a sense of what it’s all about, and they might recognize a bit here or there.

For the third part, I’d briefly recap the problem and describe how you solved it in non-technical language, and then do your live-coding extensibility whiz-bang demo. Even if the non-CS/SE folks don’t understand the demo, they’ll see eye candy flying by and your professional peers and faculty all nodding and smiling, so they’ll think it’s cool.

I once attended a seminar by a guy who won the Nobel Prize for applying chaos theory to chemical systems. He applied this approach, so even though all the non-theoreticians like my fellow organic chemists and I were all completely out of our depth, the fact that the theoreticians were all excited left us feeling like it was a great seminar even though we didn’t have a clue about what he’d said.
