Then a clear hour of development time to finish some Python tests for a new feature you’re developing in Airflow, collaborating with André on T-SQL support in the pipeline, some fun technical conversations. The team reviews the design for the semantic layer that Prabha and Freek completed yesterday, then lunch!

    The team reduced a 4 hour stock process to just 20 minutes and you’re all proud to show this at the sprint demo. In the afternoon, the team and the PO plan the upcoming sprint. Then a cloud migration progress update with the PO of deployment team and aligning on the sequence order of the remaining stories in the epic. Just before you head home the team has fun deciding their outfit theme for the Coolblue party.
