While most break room conversations revolve around current events or the latest family drama, Research Statistician Developers Ryan Lekivetz and his colleague, Joseph Morgan, can’t stop talking about arrays. In this featured presentation, Ryan Lekivetz, part of SAS’ DOE team, explains the use of covering arrays as an experimental design for validating software systems. Ryan introduces a number of ways of efficiently testing complex engineered systems… to force a fault to induce a failure. Critically important in software, the concepts apply to any industry where an efficient, disciplined approach to testing is critical.
