Flip it and Reverse It

Reverse Engineering a Branched Scenario 

July 5, 2022

This week I took on the task of reverse engineering a branched scenario high level design document. There are a lot of instances where you might want to work backwards in order to explore how something was built or designed, and a branched scenario e-learning is one of them. Courses can be very complex, but reverse engineering them allows you the opportunity to break the process down and understand it. 

In a nutshell, reverse engineering is starting with a finished product, and recreating that product through detailed construction of each aspect of it. You're working backward, but it is a useful learning tool to understand how and why something was constructed the way it was. It also allows you to pay attention to small details in the design. Instructional designers can learn a lot from others work. Not only does it potentially give you new ideas, it can also introduce you to new concepts, patterns, and quality of work. Not everything is created from scratch, and there is something to be said about being able to analyze something and enhance what is already there. 

Branching

The example course that I've chosen to reverse engineer is called A Support Net from The Open University. It is a deep branching video scenario, and you choose a character to help.  I chose the first option, a school girl named Lily who is struggling to settle in at her new school. The scenario follows her general mental state around school, and as the user, you find out that she is very anxious.

I took the time to explore every pathway, and constructed a visual pathway for the scenario using Diagrams.net. This way, you can truly see the branching:

Key Takeaways

Though I previously had no experience critiquing a design document, or reverse engineering, I think I gained a lot from this experience.
