27. Previous work
Digital Twin Maturity has been
defined as:
• the evolution through time
of Digital technology
(Kalwani, 2017).
• a spectrum of ‘what it does’
(Evans, 2019; Boje et al.,
2020).

28. Iterative design
Maturity levels
Collects data
Context (data storage, historic data)
Models + predictions
Exploration (scenario testing, interaction)
Optimisation
Autonomous

29. Exploratory
Projects
2020-2:
The
uncertain
half
of
the
twin…getting
a
grip
on
uncertainty
with
DT
No certainty
of relevant
knowledge
Status twin
(Twin will monitor
variables)
Certainty of
relevant
knowledge
Consensus
on values
No consensus
on values
Autonomous Twin
(Twin can be used to
optimize, process and
control data)
Predictive Twin with
process model
(Twin will be used to get
raw values at new
location)
Predictive Twin with
machine learning
model
(Twin will be used to
understand patterns)
We can map out what type of twin is needed for a certain situation…
Choosing the right twin
