Usability Task-Flow Funnel Simulator

Monte Carlo simulator of a mobile onboarding task flow: watch a population of simulated test users step through UI screens, retry or abandon based on a tunable error probability, and see completion rate, time-on-task and an estimated SUS score converge live.

Task-based usability testing scripts a group of real users through a fixed flow of screens and scores the run with a handful of standard metrics — completion rate, time-on-task, error rate, and a SUS estimate. This simulator runs that same protocol as a Monte Carlo model: a batch of simulated users steps through a chain of onboarding screens rendered in 3D, each one drawing from a per-screen advance / backtrack / abandon probability that you control, while completion rate, mean time-on-task, and an illustrative SUS score update live as the batch finishes.
