RAIRC03-BP07 Measure user controllability of system behavior

Plan how you'll test user controls before building your system by deciding which control mechanisms matter most for user safety based on your RAIBR02 risk assessment findings. Create simple test scenarios that check if each control works as intended and build basic measurement tools that show whether user inputs can change system behavior. This upfront planning saves time later and assists you to build controls that work when users need them.

Design tests that check how well users can fine-tune your system's behavior, from small adjustments to major changes. Test both precise control scenarios where users make small tweaks and broad control scenarios where users need to make big behavioral shifts. Include tests that push controls to their breaking points to determine where the system stops responding to user input, which assists you to fix weak spots.

Build ways to measure how fast your system reacts when users try to override, adjust, or roll back its behavior. Track how long controls take to activate and how quickly the system settles into new behavior patterns after users make changes. Fast, reliable control response keeps users in charge of the system.

Create tests that catch when controls fail or cause unexpected problems elsewhere in your system. Test what happens when users try controls that should fail gracefully and verify that your system gives clear feedback when controls can't work. Look for cases where adjusting one thing accidentally breaks something else, as surprise effects can undermine user trust.
