I started with researching the highly complex theory underlying alerting systems' parameterisation.
Next, I created a paper prototype that allows administrators of alerting systems to set parameters specific to the filtering algorithm employed by their system.
After several iterations of paper prototyping, I created a digital prototype of the same interface in Balsamiq. It was the foundation of several expert evaluations.
My student developed a digital C# prototype after I incorporated the resulting changes into my Balsamiq prototype. The C# prototype was used for a user study.
