The Hidden Pattern Behind Most Legacy CRM Failures
Author(s): Eshita Nandy
Originally published on Towards AI.
A decade of Oracle Siebel and legacy CRM work revealed one hidden pattern behind most enterprise system failures.
Three years ago, I joined what was supposed to be a routine troubleshooting call. A business user had raised a ticket saying a CRM report looked wrong. Not broken. Not failing. Just… off.

Across five real incidents spanning Oracle Siebel, CRM reporting pipelines, production releases, and even AI integrations, the author finds that the most damaging failures rarely begin with a system that is broken. Instead, they start when teams treat something as “understood” simply because it hasn’t visibly failed—an assumption gap the author calls “assumption debt.” The article explains why this pattern is hard to detect (silence looks like validation), what finally exposes it (fresh, direct inspection of the unchallenged parts), and how improvements come less from adding more process and more from periodically distrusting and re-verifying long-unquestioned components.
