Phase 1: Product Design Review
Process Overview
The purpose of the Product Design review (Phase 1) is to ensure that the outputs of Product Design satisfy the criteria required to move forward to Phase 2 (Software Design). This review validates that the product concept, intended use, and high-level requirements are clearly defined and ready for technical implementation.
According to GP-012, Phase 1 establishes the foundation for all subsequent development phases.

Context of Initialization
This project was initiated to develop Legit.Health Plus Version 1.1.0.0, a medical device software designed for dermatological diagnosis and disease tracking. The device addresses the medical need for objective, consistent, and scalable assessment of skin conditions using AI/ML-powered image analysis.
Key technological elements include:
- Machine learning models for skin condition recognition
- Image processing and analysis
- User interface for clinicians
- Integration with healthcare systems
This is an evolution of previous versions, incorporating regulatory compliance improvements and enhanced functionality for EU MDR and FDA requirements.
