Validation Techniques

Validation techniques comprise a essential set of methodologies used across various fields to ensure that systems, data, or processes meet specified requirements and fulfill their intended purpose. These techniques form the backbone of quality assurance practices and are crucial for maintaining data integrity.

Core Components

1. Data Validation

• Input validation to verify data format and range
• Cross-reference checking against known reliable sources
• Statistical analysis for outlier detection
• Consistency checks across related data fields

2. Process Validation

• Workflow analysis to verify process steps
• Performance testing against established benchmarks
• Documentation review and verification
• Standard Operating Procedures compliance checking

3. System Validation

• Software testing methodologies
• Integration testing across system components
• User acceptance testing
• Security validation protocols
