The failure crosses Technology, Data and Operations before anyone can explain it.

Some organisations rely on systems few people are willing to change.
One day, its turn comes.
PLATFORM DATA RISK
Last time anyone touched it, three other systems broke.
Cosmogenesis reads the source code your organisation runs.
It draws the lineage between systems, data and operations.
Critical dependencies and risks surface before a change is made.
