Start with the system boundary
Define the physical asset, available data, and who owns operational decisions. A public demonstration should never imply control of safety-critical equipment.
Use the twin to ask better questions
A digital twin is a model with assumptions. Sensitivity analysis can expose which measurements matter most, but model output still needs validation.
Deliver a testable next step
A valuable output describes an experiment, acceptance criteria, evidence gaps, and a human approval gate. It is not a guarantee of improved performance.
