Case: Eliminating More System Defects with T-VEC Solutions

The Problem

Manual techniques were missing significant numbers of requirement and code defects

Company R, supplier of aircraft avionic software and systems, wanted to find a method to identify defects more rigorously than through manual inspection and manually generated tests.

  • Company R spent too much time and money identifying defects and testing a key component of their avionic flight guidance system (FGS) product family.
  • Each upgrade of the FGS software increased the complexity, making defects more difficult to identify with manual inspection and testing.
  • Many defects discovered late cost more to fix and resulted in schedule delays.
  • Defects in avionics systems were unacceptable due the safety critical nature of the software.
  • Rework caused by late detection of defects were impacting customer deliveries and significantly eroding the profits of this crucial business product.
  • The Problem
    Manual techniques were missing significant numbers of requirement and code defects
  • The Approach
    Automated analysis of modeled requirements with test generation
  • Implementation
    Apply T-VEC automated solution while comparing results with current manual processes
  • Results
    T-VEC solutions identified defects missed by manual and other tools and method
