Digital Twin Maturity Model Exploratory Phase

The next step on the journey is the creation of digital twin capabilities around a defined use case which involves a small number of open data sets across 2 domains (e.g. transport volume and air quality). This approach allows a first foray into the world of predictive modelling, enabling the city to test interoperability. 

Key enablers for this stage include digital capabilities to model and understand data, funding to enable the innovation pilot and the ability to test the digital twin play.

Questions to address at this stage include:  What outcomes/use case needs to be achieved? Is there buy-in from the relevant stakeholders from both domains? Is the data needed available?  What existing analytics  models can be leveraged? What contractual/legal obligations and/or restrictions are there for the data?  Does the data need processing/cleaning/formatting?
