Mission & Safety Critical Software Reliability Services
ALD helps engineering teams attain strict software dependability, availability, and safety requirements. From early lifecycle Reliability Allocation to Software FTA and Growth Modeling.
Operational Profile Analysis
Software failure occurs only when a fault is encountered during operational execution. ALD prioritizes testing by establishing occurrence probabilities for major software operations.
Eliminate Latent Faults
Target high-usage and safety-critical exception handling code early in development.
Software Reliability Engineering Tasks
Comprehensive methods and lifecycle support led by ALD experienced software reliability engineers.
Reliability Allocation
Derives software requirements from overall system reliability goals, balancing cost, testing schedules, and readiness levels.
Test Preparation & Planning
Optimizes new test case allocation based on operational profiles, load testing, performance targets, and exception handling.
Reliability Growth Models
Applies mathematical reliability growth models to failure data to predict time to market, outage frequency, and remaining defects.
Software FTA (Fault Tree)
Analyzes root software conditions leading to top-level hazardous events, identifying critical safety paths.
Software FMEA
Evaluates software failure modes, single-point weaknesses, variable corruptions, and functional fault mitigation strategies.
Safety Requirement Analysis
Ensures completeness of requirements for safety-critical systems, verifying exception conditions and fault isolation handlers.
