FIDO Quality Control & Process Improvement 5

Question 1

A FIDO implementation team introduces 'error budgets' inspired by Site Reliability Engineering (SRE). How does an error budget relate to quality control for a WebAuthn relying party?

Accepted Answer

It defines the acceptable failure rate per SLA period; exceeding it triggers a quality improvement sprint instead of new feature work

Answer

SRE error budgets quantify allowable unreliability (100% minus SLA); when consumed, teams must prioritize reliability fixes over new features.

Question 2

A FIDO authenticator QA team wants to prioritize test cases by risk. Which factor is LEAST relevant when assessing risk for a specific test case?

Accepted Answer

The color of the test case documentation template

Answer

Documentation template aesthetics have no bearing on failure likelihood or impact, making them irrelevant to risk-based test prioritization.

Question 3

When a FIDO metadata statement is updated in the FIDO Metadata Service (MDS), what quality control step should a relying party perform before applying the update?

Accepted Answer

Validate the updated metadata statement's signature against the MDS root certificate before trusting the new data

Answer

MDS metadata statements are signed; verifying the signature against the trusted root ensures the update is authentic and has not been tampered with.

Question 4

A process improvement initiative uses value stream mapping for FIDO authenticator certification. Which type of time in the value stream should be minimized?

Accepted Answer

Wait time between process steps (queue time)

Answer

Value stream mapping targets non-value-adding wait time (queue time between steps); active work steps add value and should not be arbitrarily cut.

Question 5

A FIDO certification lab uses acceptance sampling to inspect a batch of authenticator tokens. The lot is rejected. What does this mean for the batch?

Accepted Answer

The entire batch fails the quality gate because the sampled defect rate exceeded the acceptable quality level (AQL)

Answer

In acceptance sampling, a rejected lot means the defect rate in the sample exceeded the AQL, and the entire batch is considered non-conforming.
