Abstract

Systems are increasingly software-reliant and interconnected, making design, analysis and evaluation harder than in the past. While new capabilities are welcome, they require more thorough validation. Complexity could mean that design flaws or defects could lead to hazardous conditions that are undiscovered and unresolved.

In this podcast, Dr. Sarah Sheard discusses a two-year research project to investigate the nature of complexity, how it manifests in software-reliant systems, such as avionics, how to measure it, and how to tell when too much complexity might lead to safety and certifiability problems.
