In the same paper, authors identified 6 steps necessary in their opinion to build functional Digital
Twin.

The steps are outlined below, but it is important to mention that different industries might take
different approaches, add steps or remove some of them, possibly perform some concurrently or
outsource some elements to external entities.

Step 1: Build the virtual representation

The representation normally comes in shape of CAD files and 3D modelling. Since CAD is commonly
used in product design, the files are usually ready, however for the purpose of Digital Twin, it is
advisable to not only include geometric model, but also expected product behaviour and rules.
Behaviour might describe intended purposes and user interactions, while rules relate to product
optimisation, maintenance and evaluation.

Step 2: Data processing to enable and facilitate feedback from physical product to virtual model.
