Target Canada supply-chain software failure
Target's expansion into Canada collapsed within two years, with the company closing all 133 Canadian stores and taking a loss of more than $2 billion (US), one of the most expensive retail failures in North American history.
The damage was public. The root cause was preventable.

What the software actually got wrong
A new, unfamiliar SAP-based supply-chain and inventory system produced inaccurate inventory data across the new Canadian stores, leaving many shelves empty of popular items while warehouses were overstocked with unsellable goods, a core operational failure that Target could not fix quickly enough to save the venture.

Requs AI Edge Case flags this exact pattern at the requirements and architecture stage — before a single line of code implementing it exists — so the assumption behind it gets challenged while it is still cheap to fix.
Beyond code coverage and "shall" testing
Root causes like this one rarely show up in code coverage or requirements-compliance testing, because nobody wrote a requirement anticipating the specific edge case that broke. Requs AI Edge Case and Requs AI Software FMEA are built to surface exactly this class of overlooked failure mode — before the software is written.
Surfaces this before code exists
Identifies edge cases like this one at requirements and architecture time, using the Common Defect Enumeration to catalog failure patterns seen across hundreds of real-world software failures — including this one.
Connects the failure mode to the hazard
Traces this class of root cause directly to the system-level hazard it can produce, so a defect pattern like this one gets flagged during design review instead of after it ships.
Find the overlooked root causes before they ship.
