The lack of a continuous data chain from development to operation leads to isolated information silos, manual media breaks and thus to delayed decisions.
Inconsistent and incomplete master data and engineering information undermine automation, correct generation of artifacts and trust in the digital twin.
Non-standardized, ad-hoc solutions and a lack of modularization lead to a build-up of technical debt, which makes subsequent changes and scaling more expensive.
Errors that are discovered late (e.g. due to a lack of standardization or inconsistent views) cause costly rework and extend time-to-market.
Without prior testing: The lack of virtualized tests / virtual commissioning (SiL/HiL, simulation) increases the risk of expensive functional errors and delays in real commissioning.
