Quick Start Presentations
Quick Start Presentations are short, highly focused presentations designed
to quickly familiarize viewers with a single topic. These presentations are ideal for time slots
of 10 to 15 minutes. They have been successfully used as: 1) planned interstitial content within
longer events or meetings, and 2) "bonus" presentations appended to events that have not run as
long as desired.

Quick Start: Rails:
This presentation provides a brief, non-technical overview of Ruby on Rails, suitable for
both management and technical professionals. For an audience of Rails "newbies", the
focus of the presentation is just on educating viewers about Rails. For a more experienced
audience, the spin is typically on how the audience can effectively educate others about Rails
as a technology. |
