Field failure investigation
Structure incomplete or noisy field data, reproduce the failure mode, and separate symptoms from the controlling mechanism.
Field quality engineering
Resolve the failures your customers experience—and keep them from returning.
Runner Engineering connects field evidence, product physics, test results, manufacturing variation, suppliers, and design intent to identify root cause and deliver corrective action that survives technical review.
Discuss your challengeWhat we solve
Engineering work tied to measurable outcomes.
Root cause and containment
Define immediate risk controls while using fault trees, experiments, teardown evidence, and first-principles analysis to isolate cause.
Corrective action validation
Translate findings into design, process, supplier, or software changes and verify that the solution closes the actual failure mode.
Reliability improvement
Build test strategies, accelerated-life evaluations, and closed-loop lessons that reduce warranty exposure and prevent recurrence.
How the work proceeds
- 01Frame the failure signature, population, severity, exposure, and known evidence.
- 02Develop competing hypotheses and select the fastest discriminating analyses or tests.
- 03Confirm root cause, quantify risk, and define technically justified corrective actions.
- 04Validate effectiveness and document a traceable decision record.
Strong project fit
- ■Recurring failures that have resisted prior investigation
- ■High warranty, return, service, or customer disruption
- ■Safety, compliance, or reputation-sensitive product issues
- ■Cross-functional problems spanning design, manufacturing, suppliers, and software
