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

Automatically generating test scripts from the specification

Answer

Reducing the number of test cases needed for certification

Answer

Mapping FIDO metadata entries to hardware SKUs

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

Pareto chart

Answer

Fishbone diagram

Answer

SIPOC diagram

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

The number of test cases required for each failure mode

Answer

The percentage of units expected to fail in the field

Answer

The FIDO certification score assigned during conformance testing

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

Both FAIL and WARN, because all findings block certification

Answer

Only the WARN, because optional features carry more risk

Answer

Neither, because conformance tests are advisory only

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

Immediately add the critical defect regardless of the WIP limit

Answer

Move all WIP items to 'Done' without resolving them

Answer

Increase the WIP limit to 4 to accommodate the new item

Question 6

A FIDO relying party conducts user acceptance testing (UAT) for a new WebAuthn registration flow. UAT passes but post-launch error rates spike. What quality process failure likely occurred?

Accepted Answer

UAT did not adequately represent the diversity of real user devices and browsers

Answer

The attestation format was changed after UAT

Answer

The server's CBOR decoder was not included in the UAT scope

Answer

The FIDO metadata service was offline during UAT

Question 7

Which lean quality principle best describes removing the manual step of having a developer sign off attestation format checks that automated FIDO conformance tooling can already verify?

Accepted Answer

Eliminate waste (muda) by automating redundant manual steps

Answer

Implement poka-yoke to prevent defects at source

Answer

Apply Just-In-Time delivery to reduce inventory

Answer

Use value stream mapping to identify bottlenecks
