Inputs, processes and outputs, and how mechanisms and code produce controlled behaviour.
These are the statements the Design and Technology Year 8 syllabus makes about Systems and Control. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.
Systems thinking: input, process, output - Systems and Control, Year 8.

Structural principles and forces - Systems and Control, Year 8.
Microcontrollers and inputs - Systems and Control, Year 8.
Writing control algorithms - Systems and Control, Year 8.
Feedback and control loops - Systems and Control, Year 8.
Testing a system - Systems and Control, Year 8.
Debugging a control system - Systems and Control, Year 8.
Year 8 Assessment Task Shape is 50 marks in 75 minutes. Questions on Systems and Control are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Design and Technology Year 8 uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Systems and Control is module 2 of 3 in Design and Technology Year 8. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Design and Technology Year 8 dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
