Data architecture

https://www-notation.tkblueagency.com/


Only stakeholders are granted access to TK'Blue

In the future, other interested users will be able to check the results in the CSRD or the Global Supply Chain dashboard (after the end of the PO2 separation)

In the meantime, you may contact your GBU representative

Governance Process/ Roles and responsibilities


Data to feed TK'Blue is extracted every month from BW TIERS, all GBUs in a single file.

On the 3rd day of the month, data of the previous month is sent to a GCP folder. (eg, data of December 2024 was extracted automatically on January 3rd 2025)

Every month, the business coordinator gets to the GCP Folder, downloads the latest extraction and uploads it to TK'Blue

TK'Blue processes the data and the business leader will notify the GBU key users.


GBU key users are expected to check and correct the errors before the 20th of the month.

See how to in the recording of the training (at 15:49 about the incorrect entries)

Once data is processed by TK'Blue, indicators will be available in the platform for the GBU key users.


On the 28th of the month, data is pushed by TK'Blue in an SFTP folder, connected to the internal datalake.
