Brownfield approach (Already existing ECC system) : KTern helps in migration of have already established ECC system into SAP S/4 HANA system. After the migration it is important that the new system is compatible, so to help with that KTern uses Custom Process Adoption from Digital Process to make the system compatible.

Greenfield Approach: The system following the greenfield approach means the entire implementation is new, while the SAP S/4 Hana is analysed based on what is the best way to configure the same, KTern's Digital process helps in optimization of the process by providing the best recommendations regarding the practices which can be followed for the business process

Hence, KTern's Digital process benefits both greenfield as well as a brownfield in different manner.
