Year 11 QCE Digital Solutions Unit 2: Decomposition and solution requirements
Students break data-driven problems into manageable parts using decomposition and pattern recognition, then gather and write functional, non-functional and constraint requirements and sort them into inputs, processes, outputs and storage.
One content description from the full QCE Digital Solutions Unit 2 — Data-Driven Problems and Solution Requirements journey. All 21 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
