Case Study #302 — 309 Software Failure Events Timeline

FAFSA 'Better FAFSA' rollout disaster

The US Department of Education's overhauled federal student-aid application launched months late and then miscalculated financial need for several hundred thousand students, delaying college financial-aid decisions nationwide and contributing to a sharp nationwide drop in completed applications.

02 — The Root Cause

What the software actually got wrong

GAO found the department rushed an incompletely tested, down-to-the-studs technical rebuild of the FAFSA system, including a formula bug that omitted cash, savings and investment data from dependent students' calculations; inadequate pre-launch testing (which should have included large batches of hand-calculated test cases) let this and several other defects reach millions of real applicants.

How Requs AI Catches This

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.

How Requs AI Catches This

Requs AI Software FMEA traces this failure mode back to the system-level hazard it feeds, tagging it against the Common Defect Enumeration so it surfaces in review instead of in the field.

03 — How This Gets Caught Before It Happens

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.

Requs AI Edge Case

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.

Requs AI Software FMEA

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.
