Student Guide (IB Design Technology)

Simple Explanation: Think of a digital twin as a super-smart, live computer model of a real-world thing, like a chemical plant. It uses real data to show exactly what's happening, predict problems before they occur, and let you test out changes safely on the computer first.

Why This Matters: Understanding digital twins helps you design systems that are not only functional but also adaptable and can be continuously improved based on real-world performance.

Critical Thinking: How might the complexity and cost of developing high-fidelity digital twins limit their adoption in smaller-scale design projects or by independent designers?

IA-Ready Paragraph: The adoption of digital twin technology, as highlighted by Mane et al.
