In high-mix environments, automation fails for predictable reasons. Constant rework turns every changeover into a manual project, where small deviations cause stops and improvements require specialist intervention. Extended deployment cycles delay time-to-value due to custom integration and manual reprogramming for every new task. High changeover costs emerge as frequent shifts in parts, jobs, and priorities add significant expense. Fragile runtime performance causes systems to break down whenever real-world conditions do not match the script.
