FIDO Quality Control & Process Improvement 3

Question 1

A quality engineer creates a traceability matrix linking FIDO specification requirements to test cases. What is the primary benefit of this artifact?

Accepted Answer

Ensuring every specification requirement has test coverage and no requirement is untested

Answer

A requirements traceability matrix (RTM) guarantees bidirectional coverage: every requirement maps to tests, and every test maps back to a requirement.

Question 2

Which statistical process control (SPC) tool would best help a FIDO hardware team monitor whether biometric sensor accuracy is drifting over production batches?

Accepted Answer

Control chart (X-bar and R chart)

Answer

Control charts track a process metric over time with control limits, making drift and out-of-control conditions immediately visible across production batches.

Question 3

A FIDO authenticator manufacturer implements FMEA (Failure Mode and Effects Analysis) before releasing a new product. What does the Risk Priority Number (RPN) represent?

Accepted Answer

Severity × Occurrence × Detectability, used to rank failure modes by risk

Answer

RPN = Severity × Occurrence × Detectability; higher RPNs indicate failure modes requiring the most urgent corrective action.

Question 4

In a FIDO conformance test run, a test suite reports 'WARN' for an optional feature and 'FAIL' for a mandatory requirement. Which finding must be resolved before certification?

Accepted Answer

Only the FAIL, because mandatory requirements are non-negotiable for certification

Answer

FIDO conformance testing requires all mandatory requirements to pass; optional features generating WARNs do not block certification.

Question 5

A Kanban board is used to manage a FIDO authenticator bug backlog. A column labeled 'WIP Limit: 3' is full. What should the team do when a new critical defect is discovered?

Accepted Answer

Finish or escalate an existing WIP item before pulling the new defect into that column

Answer

Kanban WIP limits exist to prevent multitasking overload; the correct action is to clear or escalate existing work before adding new items, even critical ones.
