ENV-004k — Record Environmental Variation

Go to ENV-004 — Provide Deterministic Test Environment

The DIDO-TE SHALL record each detected environmental variation.

• ENV-004 — Provide Deterministic Test Environment
• ENV-004j — Detect Environmental Variation
• [DTE5] DIDO-TE Requirements Register, source requirement identifier and obligation to be assigned
• [DTE6] Structured Information Processing Reference Architecture (SIP-RA)
• [DTE7] Federated Data Interpretation Systems Reference Architecture (FDIS-RA)

A detected environmental variation identifies a difference between an observed environmental condition and the condition specified by the applicable Test Definition.

Detection without a persistent record provides insufficient support for later analysis. The record preserves the identity of the affected condition, the expected condition, the observed condition, and the circumstances surrounding the variation.

Environmental-variation records support interpretation of Test Results. They also support Traceability, Reproducibility, Comparability, and assessment of environmental determinism.

• Test Environment
• Test Definition
• Test Execution
• Test Object
• Node
• Test Resource
• Baseline
• Configuration
• Evidence
• Test Result

Verification confirms that:

• The DIDO-TE creates a record for each detected environmental variation.
• Each record identifies the affected environmental condition.
• Each record identifies the expected condition.
• Each record identifies the observed condition.
• Each record identifies the applicable tolerance.
• Each record identifies the occurrence time.
• Each record identifies the duration, where applicable.
• Each record identifies the affected Test Environment element.
• Each record identifies the associated Test Execution.
• Each record identifies the detection mechanism.
• Each record preserves the detected variation as Evidence.
• Each record maintains Traceability to the applicable Test Definition and Test Results.
• Each record receives protection against unauthorised modification or deletion.
• An omitted, incomplete, altered, unprotected, or untraceable environmental-variation record constitutes nonconformance with this requirement.

Verification includes:

• Inspection of environmental-variation records
• Comparison of detected variations with their corresponding records
• Inspection of expected conditions, observed conditions, and tolerances
• Inspection of occurrence times and durations
• Inspection of affected Test Environment elements
• Inspection of Evidence protections
• Inspection of Traceability records
• Testing with environmental variations affecting different controlled conditions
• Confirmation that the DIDO-TE records each detected variation
• Confirmation that an omitted or incomplete record produces a nonconformance result

• Add links to the architecture sections governing environmental monitoring, environmental variation, Evidence, Test Results, and Traceability.

Assign the applicable delivery phase.
