Using CogTool and the KLM method, I compared how long it takes to book a flight in two different platforms, Easyjet and TAP.
After collecting and analyzing data, I was able to find the design flaws of the platforms and produce a report with recommendations to make the process quicker.
"Part of the GOMS family of predictive models, the Keystroke-Level Model GOMS (KLM-GOMS) is a quantitative modeling tool for predicting how long it will take expert users to complete a specific task with no errors. KLM-GOMS predicts task times based on a simple set of physical and mental operators including keystrokes, button clicks, pointer movement, keyboard to mouse movement, and thinking time. Each KLM operator is assigned a time based on empirical research. To obtain the predicted time for a task, you add the times for individual operators." [http://www.usabilitybok.org/klm-goms]
