✏️ Research Phase - Business Requirements Analysis
During our initial discussions with QuickTest Academy’s training division, they shared comprehensive insights from their existing trainer network and learner feedback data.
Key findings from QuickTest Academy’s business intelligence:
- Trainer pain points: Current evaluation methods are time-consuming and lack engagement - trainers spend 30-45 minutes creating assessments
- Learner engagement: Traditional paper-based quizzes show 40% lower engagement compared to interactive digital formats
- Session efficiency: Training sessions lose momentum during evaluation phases due to preparation time
QuickTest Academy’s market positioning insights:
- 85% of trainers prefer mobile-first solutions for portability
- Target demographic values simplicity over feature complexity
- Critical success factor: quiz setup must be under 2 minutes to maintain training flow
- Interface benchmarking: clean, professional design similar to educational apps
Strategic direction confirmed: Based on QuickTest Academy’s data and trainer feedback, we validated that the MVP should focus on pre-loaded question banks with instant configuration, rather than custom question creation. The goal was to eliminate preparation friction while maintaining educational effectiveness.
Key Insights:
- 90% of training sessions benefit from general knowledge assessments
- Interface must be energetic yet professional (reference: educational platforms)
- Critical configuration time: maximum 2 minutes setup
