Governed Space

Validation Scope Definition

Canonical Definition

Validation Scope Definition Module (VSCDM) defines the governance
framework for establishing, bounding, documenting, maintaining, and
controlling the specific dimensions of a Validation Object that are
included within or excluded from a governed validation process.

It establishes the conditions necessary to translate an approved
Validation Purpose into an explicit Validation Scope capable of
defining what the validation will examine without confusing
validation scope with the structural boundary of the Validation
Object itself.

Operational Role

VSCDM governs the scope-definition layer of Validation Purpose &
Scope governance.

Its role is to determine which characteristics, functions,
behaviors, states, environments, use cases, populations, periods,
dependencies, or other validation-relevant dimensions of an
established Validation Object must be examined to satisfy the
approved Validation Purpose.

VSCDM creates the governed perimeter of the validation activity.

Module Operational Space

VSCDM governs:

• Validation Scope definition,
• scope boundaries,
• scope inclusion,
• scope exclusion,
• validation dimensions,
• functional coverage,
• behavioral coverage,
• environmental coverage,
• temporal coverage,
• use-case coverage,
• population coverage,
• dependency coverage,
• scope assumptions,
• scope ambiguity,
• scope change,
• and scope traceability.

Module Function

VSCDM applies after the Validation Purpose and objective have been
sufficiently established.

Its function is to prevent:

• undefined validation coverage,
• validation activity that cannot satisfy its stated purpose,
• accidental omission of materially relevant dimensions,
• uncontrolled expansion of validation coverage,
• confusion between object boundary and validation scope,
• assumptions that validation covers the entire Validation Object,
• hidden exclusions,
• and validation determinations being interpreted beyond the dimensions actually examined.

Object Boundary and Validation Scope

VSCDM establishes a critical VALIDOS™ distinction:

Validation Object Boundary defines what the object is.

Validation Scope defines what aspects of that object the
validation examines.

These concepts must not be treated as interchangeable.

A Validation Object may contain many components, functions, states,
behaviors, or environments while a particular validation examines
only a governed subset of them.

The existence of an element within the Validation Object boundary
does not automatically mean that the element has been included
within Validation Scope.

Scope Dimensions

Validation Scope may be defined across multiple dimensions depending
on the Validation Object and Validation Purpose.

Relevant dimensions may include:

Structural Scope

Which components, subsystems, layers, or structural elements are
included in validation.

Functional Scope

Which functions or capabilities are examined.

Behavioral Scope

Which behaviors, outputs, interactions, or response patterns
are included.

Operational Scope

Which operational conditions, workflows, processes, or deployment
situations are examined.

Environmental Scope

Which technical, physical, organizational, social, regulatory, or
other environments are included.

Temporal Scope

Which time periods, operating windows, historical periods, or future
conditions are covered.

Population Scope

Which users, affected populations, customer groups, operators, or
other relevant populations are included.

Use-Case Scope

Which intended uses, applications, decisions, or operational
scenarios are included.

Dependency Scope

Which dependencies and external relationships must be considered
within validation.

Scope Inclusion

VSCDM requires material inclusions to be explicit.

Included dimensions should be sufficiently described so that
subsequent validation governance can determine what must be
addressed through criteria, methodology, evidence, and execution.

Inclusion should not be inferred merely from the existence of a
relationship with the Validation Object.

Scope Exclusion

Material exclusions must also remain explicit.

An exclusion identifies a validation-relevant dimension that exists
but is not covered by the governed validation.

Exclusions may arise because:

• they are irrelevant to the approved Validation Purpose,
• they are governed by another validation,
• they are unavailable for examination,
• they fall outside the intended use,
• they require a separate methodology,
• or another justified condition exists.

An exclusion must not silently disappear from the interpretation of
the eventual validation determination.

Scope Completeness

VSCDM evaluates whether the proposed Validation Scope is
sufficiently complete to support the approved Validation Purpose.

Scope completeness does not mean that every possible characteristic
of the Validation Object must be examined.

It means that no dimension materially necessary to satisfy the
approved Validation Purpose has been omitted without explicit
governance justification.

Minimum Implementation Framework

1. Translate Purpose into Scope Requirements

Determine which dimensions of the Validation Object must be examined
to satisfy the approved Validation Purpose and objective.

2. Establish Scope Inclusions

Identify and document the characteristics, functions, behaviors,
environments, use cases, populations, periods, dependencies, and
other dimensions included within validation.

3. Establish Scope Exclusions

Identify material dimensions that remain outside Validation Scope
and document the basis for their exclusion.

4. Assess Scope Completeness

Determine whether the resulting scope is sufficiently complete to
support the Validation Purpose.

Where material gaps exist, the scope must be revised, the purpose
constrained, or the limitation explicitly governed.

5. Preserve Scope Traceability

Maintain:

• scope definition,
• included dimensions,
• excluded dimensions,
• scope assumptions,
• scope justification,
• scope changes,
• relationship to the Validation Purpose,
• timestamps,
• and sufficient traceability throughout the validation lifecycle.

Scope Change Governance

Validation Scope may change after validation begins.

Material scope changes may include:

• adding or removing system components,
• introducing new use cases,
• expanding populations,
• changing operational environments,
• extending temporal coverage,
• adding previously excluded behaviors,
• changing dependency coverage,
• or materially reducing existing coverage.

Material scope changes must be governed rather than
silently incorporated.

Where necessary, changes must propagate to subsequent validation
criteria, methodology, evidence requirements, execution,
and determinations.

Scope Expansion

Expansion of Validation Scope does not automatically extend existing
validation results to the newly included dimensions.

Newly introduced scope elements may require:

• additional criteria,
• different methods,
• additional evidence,
• new sources,
• further execution,
• or separate validation determinations.

A broader declared scope therefore requires corresponding
validation support.

Scope Reduction

Reduction of Validation Scope may affect whether the original
Validation Purpose can still be satisfied.

Where a material dimension is removed, VSCDM must determine whether:

• the Validation Purpose remains supportable,
• the purpose must be narrowed,
• the validation becomes conditional,
• or validation can no longer satisfy its original mandate.

Use Case 1 — AI System Validation

Scenario

An AI system contains language generation, document retrieval,
recommendation, and automated action capabilities.

The Validation Purpose concerns deployment of the
language-generation capability for internal knowledge assistance.

Application

VSCDM establishes language generation and the relevant retrieval
interactions within Validation Scope while explicitly excluding
automated action capabilities and unrelated
recommendation functions.

Result

The eventual validation determination cannot legitimately be
represented as validation of every capability contained within the
AI system.

Use Case 2 — Healthcare Model Validation

Scenario

A predictive model is intended for use with a defined patient
population and clinical environment.

Application

VSCDM establishes the relevant population, use case, operating
environment, input characteristics, and clinical context within
Validation Scope while documenting populations and environments
not examined.

Result

The validation determination remains bounded to the population and
conditions actually included rather than being generalized to
unvalidated clinical contexts.

Canonical Closing Statement

Validation Scope Definition Module establishes the canonical
governance framework for defining what a governed validation will
and will not examine. By governing scope dimensions, inclusions,
exclusions, completeness, change, expansion, reduction, and
traceability, VSCDM ensures that validation coverage remains aligned
with its approved purpose and that validation determinations cannot
legitimately be extended to characteristics, functions, populations,
environments, use cases, or conditions that were never within the
governed Validation Scope.
