The Business Impact of Reliability
When telecom applications fail, it costs money. A recent case study demonstrates how
strategic performance QA achieved 99.9% uptime and reduced performance incidents by
75% for a telecom operator.
The Challenge: Peak Load Failures
The telecom operator’s BSS/OSS applications were experiencing critical failures:
• System outages during high–traffic periods
• Poor customer experience with slow response times
• Inadequate testing for realistic load simulation
Forrester research shows 82% of consumers rank reliability as the top factor in telecom
service satisfaction above price.
The Solution: Two-Pronged Testing Approach
Manual Stress Testing
• Simulated extreme user scenarios
• Assessed real–world user experience under load
• Identified performance bottlenecks through direct observation
Automated Performance Framework
• Simulated 10,000+ concurrent users
• Monitored system performance metrics continuously
• Integrated performance testing into CI/CD pipelines
Implementation Strategy
• Analyzed real usage patterns to create realistic tests
• Automated 90% of performance scenarios
• Manually tested edge cases and user experience
• Integrated performance metrics into reporting
• Continuously optimized based on test results.
• Automated 90% of performance scenarios
• Manually tested edge cases and user experience
