Slides from my talk at JFall 2023

1. … in love with Java …

2. Legacy Systems
Point to point
integrations
(aka Spaghetti)
Manual work
Ad-hoc problem
solving
@berndruecker

3. 1. A broken end-to-end
automation
Local automations are
not integrated with one
another, the end-to-end
process is not fully
automated.
Lack of understanding
The end-to-end process
is not fully visible
and key metrics are
hard to track.
2. Lack of flexibility
Changing the end-to-end
process is difficult
since it leads to
potential changes in
many different systems.
