A Controlled Experiment on Incorporating Failure Knowledge into Design Decisions for Internet of Things Systems
Internet of Things (IoT) systems allow software to directly interact with the physical world. Recent IoT failures can be attributed to recurring software design flaws, suggesting IoT software engineers may not be learning from past failures. We examine the use of failure stories to improve IoT system designs. We conducted an experiment to evaluate the influence of failure-related learning treatments on design decisions. Our experiment used a between-subjects comparison of novices (computer engineering students) completing a design questionnaire. There were three treatments: a control group (N=7); a group considering a set of design guidelines (N=8); and a group considering failure stories (proposed treatment, N=6). We measured their design decisions and their design rationales. All subjects made comparable decisions. Their rationales varied by treatment: subjects treated with guidelines and failure stories made greater use of criticality as a rationale, while subjects exposed to failure stories more frequently used safety as a rationale. Building on these findings, we suggest several research directions toward a failure-aware IoT engineering process.
