## Summary

Mitch English, a product development team lead at Inertia, discusses implementing the QP (Quantum Platform) framework for a medical device blood analyzer. He explains how QP's actor model and hierarchical state machines manage concurrency and complexity better than traditional RTOS approaches. The team shares lessons on testing strategies, using CppUTest for host-based unit tests, and the architectural decision to favor publish-subscribe patterns over direct posting to improve testability.
