The web works very easy right?

Input -> Process -> Output

If your Input has already an invalid state, processing and outputting data will be unpredictable.

You can't test everything, but you should monitor it

11.10.2022 @ Nerd-BBQ at KRUU

We had an incident which did occur in our warehouse at KRUU. The downloading of the photos was very slow from one to the other day - well we thought that the problem started on this day.

Actually we did notice this very late and the problem started two years ago but we did notice this very late due to the reduced rentals because of Covid19.

This will never happen again thanks to our new metrics and alerting powered by the OpenSearch!

Kanban wird seit Oktober 2010 bei Jimdo eingesetzt, um die Kommunikation zwischen den Teams zu verbessern, die Geschwindigkeit zu erhöhen und mehr Transparenz im gesamten Unternehmen zu schaffen.
Auf diesem Wege ist Kanban ein wichtiger Bestandteil unserer Kultur geworden. Durch den Einsatz in nahezu allen Unternehmensbereichen und den Bedarf, die größer werdende Kluft zwischen digitalem Issue Tracking und analogen Kanban Boards zu schließen, haben wir JimFlow entwickelt.
