Adacel 2016 – Scenario Builder
Audience
- Air Traffic Control Instructors & Students
Context
- Instructors creating new scenarios for classes and exams
- Students selecting and launching the air trafic simulation
Double Diamond Process (4 weeks)

General Problem
“We need a new web interface to create air traffic scenarios from a tablet”
Discover phase (week 1)
- Conducted stakeholder interviews
- Conducted expert interviews
- Heuristic evaluation on legacy UI
Decide phase (week 2)
- Present research insights
- Propose usability improvements
- Propose simplified information architecture and labelling
- Agree on context requirements & hand-held device best practices
Specific Problem / opportunity
Opportunity to speed-up the creation process:
- “It takes forever to create a new scenario (3 to 5 minutes)
- “Besides the location, there’s only a few parameters that we change most of the time:
- Weather condition (clam, rainy, windy, snowy…)
- Intensity (number of aircraft per hour)
- Complexity (type of aircraft variation)
- Events (delay, spacing, collision…)

Let’s try a card-based landing page, with meta-parameters and a “start-from-previous” scenario
Design phase (week 3)
- Iterative medium-fidelity design approach with stakeholders
- Frontend stack design in mind (Angular + Material Design)
- Tested a two-size card component!
- Optimized the flow to a single screen for most used parameters
- Optimized user flow so that 80% of use cases takes less than 15 seconds
Deliver phase (week 4)
- Presented medium-fidelity interactive prototype
- Proposed high-fidelity UI mockup and basic style guide
