Governed Space
Simulation Scope
Canonical Definition
Simulation Scope Module (SSCM) defines the governance conditions under whichthe exact extent of a simulation inquiry is established, bounded, decomposed,
maintained, changed, and documented relative to the governed Simulation Object
and Simulation Purpose.
SSCM determines which object characteristics, functions, behaviors,
interactions, operating conditions, temporal ranges, spatial ranges, system
states, and inquiry dimensions are included within the simulation and prevents
simulation outputs from being interpreted beyond the scope actually governed
and executed.
Operational Role
SSCM serves as the second internal governance space of the Simulation Purpose& Scope Standard (SPSS).
The preceding Simulation Purpose governance establishes:
Why is the simulation being performed?
SSCM asks:
What exactly must the simulation cover in order to address that purpose?
The governed progression is:
Governed Simulation Purpose → Scope Requirement → Scope Dimensions → Scope
Inclusion → Scope Boundary → Scope Structure → Scope Status → Governed
Simulation Scope
SSCM transforms simulation purpose into a concrete inquiry perimeter capable
of guiding downstream Reality Representation, Assumptions, Model &
Environment, Inputs & Data, Scenario Design, Execution, and Output Governance.
Module Function
SSCM exists because knowing why a simulation is being performed does notestablish what the simulation actually covers.
A simulation can have a legitimate purpose and still fail methodologically
because its scope is: undefined, too narrow, unintentionally broad,
fragmented, internally inconsistent, misaligned with purpose, silently
expanded, silently contracted, or represented more broadly than what was
actually simulated.
SSCM therefore creates the governed relationship:
Simulation Purpose → Required Simulation
Coverage
Its function is to ensure that downstream simulation design addresses theintended inquiry without allowing omitted or unmodeled conditions to disappear
from visibility.
Simulation Scope
Simulation Scope is the governed extent of the simulation inquiry.It defines which portions of the Simulation Object and which
simulation-relevant dimensions are intended to be represented and examined.
Simulation Scope may be defined across several dimensions simultaneously.
For example:
Object: Autonomous vehicle Functional Scope: Perception and braking
Operational Scope: Urban low-speed driving Environmental Scope: Daylight and
rain Temporal Scope: Single maneuver sequence Interaction Scope:
Vehicle–pedestrian interaction
These dimensions together form the governed Simulation Scope.
Scope Must Derive From Purpose
SIMULOS® establishes:Simulation Scope should be derived from the governed Simulation Purpose rather
than from whatever the available model happens to support.
Existing simulation tools may influence implementation feasibility.
They must not silently redefine the
inquiry. Purpose–Scope Alignment
A Simulation Scope should be sufficiently broad and sufficiently detailed toaddress the governed Simulation Purpose.
A Purpose–Scope Gap exists where the purpose requires investigation of
conditions not covered by the Simulation Scope.
For example:
Purpose: Evaluate autonomous-system behavior across emergency conditions.
Scope: Normal operating conditions only.
The scope is structurally insufficient for the stated purpose.
Scope Dimensions
Simulation Scope may include several independent dimensions.These may include:
Object Dimension — which object components or systems are covered.
Functional Dimension — which functions are examined.
Behavioral Dimension — which behaviors are represented.
Operational Dimension — which operating modes or conditions apply.
Environmental Dimension — which surrounding conditions matter to the inquiry.
Spatial Dimension — where the simulation applies.
Temporal Dimension — when or for how long the simulation applies.
Population Dimension — which populations, users, actors, or entities are
represented.
Interaction Dimension — which interactions among systems or actors are
included.
Capability Dimension — which capabilities are covered.
A governed Simulation Scope may require several of these dimensions to be
combined.
Functional Scope
Functional Scope identifies which functions of the Simulation Object areincluded in the inquiry.
A system may contain many functions while only a subset is simulated.
For example:
Aircraft Simulation Object
may have scope limited to:Landing Guidance + Braking
rather than:Complete Aircraft Operation
SSCM requires this distinction to remain visible.Behavioral Scope
Behavioral Scope identifies which object behaviors are included.This may include: nominal behavior, degraded behavior, failure behavior,
autonomous behavior, human interaction, recovery behavior, emergency behavior,
or selected adaptive behavior.
A simulation of normal behavior does not automatically establish behavior
under abnormal conditions.
Component Scope
Complex systems may require explicit component-level scope.A simulation may include:
Subsystems A, B, and C
while excluding:Subsystem D
Even where the complete system remains the Simulation Object, the inquiry
itself may be partial.
Interaction Scope
Many simulation outcomes depend upon interaction among multiple components,actors, systems, or environments.
Interaction Scope establishes which relationships are included.
Examples may include: robot–human interaction, vehicle–vehicle interaction,
spacecraft–ground interaction, AI-agent–tool interaction,
system–infrastructure interaction, or subsystem–subsystem interaction.
Omitting a material interaction may create a scope limitation even where both
participating objects are individually represented.
Operational Scope
Operational Scope identifies the operating conditions or modes within whichthe simulation applies.
Examples include: normal operation, startup, shutdown, emergency mode,
autonomous mode, supervised mode, degraded mode, high-load operation,
low-resource operation, maintenance mode, or mission-specific operation.
Operating Envelope
Where applicable, SSCM may establish a governed Simulation Operating Envelope.This defines the range of operating conditions covered by the simulation.
A simulation result established within one operating envelope must not
automatically be generalized beyond it.
Spatial Scope
Spatial Scope defines the geographic, physical, or logical area covered by thesimulation.
Examples may include: one manufacturing cell, one warehouse, one city, one
orbital region, one network segment, one infrastructure zone, or one defined
physical volume.
Temporal Scope
Temporal Scope establishes the relevant time dimension.A simulation may examine: milliseconds, one operational cycle, one mission
phase, one day, one year, long-term system evolution, or another governed
period.
A short-duration simulation must not automatically support conclusions about
long-term behavior.
Population Scope
Where simulation concerns humans, users, agents, organizations, orpopulations, SSCM may define which population is included.
Population Scope may distinguish: age groups, user classes, geographic groups,
operator classes, expertise levels, organizational roles, behavioral profiles,
or other simulation-relevant populations.
Capability Scope
A complex AI or autonomous system may possess multiple capabilities.Simulation Scope may include only defined capabilities.
For example:
Perception + Navigation
may be included while:Autonomous Tool Execution
remains outside scope.This distinction must remain explicit.
Autonomy Scope
Where autonomy is material, Simulation Scope should identify the autonomylevel represented.
A simulation of:
Human-Supervised Operation
must not automatically be treated as simulation of:Fully Autonomous Operation
where system behavior materially differs.Failure and Abnormal Condition Scope
Failure conditions may be inside or outside Simulation Scope.Where the Simulation Purpose includes safety, robustness, resilience, or
failure analysis, applicable failure modes should be explicitly governed.
The absence of failure scenarios cannot later be interpreted as successful
simulation of failure behavior.
Partial Simulation Scope
SIMULOS® permits partial simulation.A simulation does not need to model the complete object or every possible
condition.
However:
Partial Simulation Scope must remain explicitly partial.
A narrow but correctly governed simulation may be methodologically stronger
than an apparently comprehensive simulation with undefined boundaries.
Scope Hierarchy
Complex simulation programs may require hierarchical scope:Program Scope
↓System Scope
↓Subsystem Scope
↓Scenario Scope
↓Execution Scope
SSCM preserves the relationship among these levels.Lower-level scope must remain traceable to the higher-level inquiry it
supports.
Scope Decomposition
A broad Simulation Scope may be decomposed into manageable subscopes.For example:
Complete Mission Scope
may be decomposed into:Launch
Transit
Orbital Operation
DockingReturn
Decomposition is legitimate when the relationship among the subscopes remains
governed.
Scope Aggregation
Multiple partial simulations may later contribute to a broader simulationinquiry.
However:
Aggregation of partial scopes does not automatically establish complete scope
coverage.
The combined scope must be assessed for: missing areas, overlaps, incompatible
assumptions, boundary gaps, interaction gaps, and uncovered transitions.
Scope Coverage
Scope Coverage describes the extent to which planned or completed simulationactivity addresses the governed Simulation Scope.
Possible coverage states may include:
Complete
Substantially Complete
PartialFragmented
Insufficient
or:Undetermined
Coverage does not determine simulation validity.It determines whether the intended inquiry has actually been represented
across its defined scope.
Scope Gap
A Simulation Scope Gap exists where a material part of the governed Simulation
Scope is not covered by planned or completed simulation activity.
Examples may include: unrepresented operating mode, missing interaction,
missing population, missing mission phase, missing failure condition, missing
capability, or missing temporal range.
Scope gaps must remain visible.
Scope Overlap
Multiple simulation activities may cover the same portion of scope.Overlap is not inherently problematic.
It may provide: redundancy, comparative analysis, sensitivity testing, or
independent representation.
However, duplicated coverage should not be confused with broader coverage.
Scope Dependency
One portion of Simulation Scope may depend upon another.For example:
Emergency Recovery Scope
may depend upon behavior established during:Failure Initiation Scope
SSCM preserves material scope dependencies to prevent isolated simulationfragments from being interpreted without required context.
Scope Interface
A Scope Interface exists where two separately governed scope regions meet.Interfaces may occur between: mission phases, subsystem simulations, model
domains, populations, operating modes, or sequential simulation stages.
Where interface behavior is material, SSCM should prevent it from falling
between separately governed scope segments.
No Scope Inflation Rule
SIMULOS® establishes:A simulation claim must not extend beyond the Simulation Scope actually
governed and covered.
Therefore:
One Function ≠ Complete System
One Scenario ≠ Complete Operational
Envelope
One Environment ≠ All Environments
One Population ≠ Universal Population
One Mission Phase ≠ Complete Mission
unless a governed basis establishes broader applicability.No Precision-for-Scope Substitution Rule
A highly detailed simulation of one narrow domain does not compensate formissing scope elsewhere.
SIMULOS® establishes:
Simulation Depth and Precision cannot substitute for missing Simulation Scope.
No Execution-for-Scope Substitution Rule
Repeating the same simulation many times does not expand its scope.More Runs ≠ Broader Scope
unless new governed conditions are actually introduced.No Model-Capability Scope Rule
The capabilities of an available simulation model must not silently determinethe governed Simulation Scope.
If the purpose requires conditions the model cannot represent, that limitation
must remain visible.
Scope Expansion
Scope Expansion occurs when new material functions, conditions, objects,populations, environments, capabilities, interactions, or periods are added to
the Simulation Scope.
Expansion may require reassessment of: Reality Representation, Assumptions,
Model & Environment, Inputs & Data, Scenario Design, Execution, Output
Governance, and Reality Correlation.
Scope Contraction
Scope Contraction removes material portions of the previously governedSimulation Scope.
Contraction may be legitimate where: purpose changes, constraints emerge,
simulation is decomposed, or a narrower inquiry is intentionally adopted.
It must remain explicit.
Scope Recomposition
Scope Recomposition changes the structure of scope without necessarily makingit strictly broader or narrower.
For example:
several subsystem scopes may be reorganized into interaction-based scopes.
The relationship to the original Simulation Purpose must remain traceable.
Scope Change Materiality
A change is material where it could alter: simulation meaning, representationrequirements, assumptions, scenario requirements, outputs, interpretation, or
downstream applicability.
Material changes should trigger downstream reassessment.
No Silent Scope Change Rule
Material Simulation Scope must not change without explicit governance.This applies both before and after execution.
No Retrospective Scope Adjustment Rule
Simulation Scope must not be narrowed after results are known merely to removefailed or inconvenient conditions from the represented inquiry.
Likewise, it must not be expanded retrospectively to make favorable results
appear more widely applicable.
Scope Ambiguity
Scope Ambiguity exists where it is unclear whether a material dimensionbelongs inside or outside the simulation inquiry.
Ambiguity may concern: functions, conditions, populations, interactions,
operating modes, environments, or time periods.
Material ambiguity must remain explicit until resolved.
Scope Conflict
A Scope Conflict exists where credible simulation records or stakeholdersdefine materially different intended scopes for the same simulation activity.
For example:
engineering may treat a simulation as:
Component Evaluation
while management presents it as:System Safety Simulation
Such conflict must be resolved or explicitly preserved.Scope Status
Possible Simulation Scope statuses may include:Established
Conditionally Established
Partially Established
Scope Ambiguous
Scope Conflicted
or:Scope Undetermined
Status describes the quality of scope definition, not the quality ofsimulation execution.
Scope Continuity
Simulation Scope should remain traceable through the full simulationlifecycle.
Conceptually:
Simulation Purpose → Governed Scope → Representation → Scenarios → Execution →
Outputs
This allows later determination of whether a simulation output actually
corresponds to the scope claimed for it.
Simulation Scope Record
SSCM should establish a persistent Simulation Scope Record capable ofreconstructing: scope basis, scope dimensions, inclusions, functional
coverage, behavioral coverage, operational conditions, environmental
relevance, spatial range, temporal range, population, interactions,
capabilities, partial scopes, dependencies, gaps, changes, and current scope
status.
Failure Conditions
SSCM governance failure may exist where: Simulation Scope is not explicitlyestablished, scope cannot be connected to the Simulation Purpose, material
scope dimensions remain undefined, the scope is insufficient for the stated
purpose, partial simulation is represented as complete coverage, material
scope gaps are hidden, different scopes are aggregated without coverage
analysis, scope interfaces remain ungoverned, scope is determined solely by
available model capability, scope expands or contracts silently, retrospective
scope adjustment occurs, materially different scopes are treated as
equivalent, or simulation outputs are represented beyond the scope under which
they were produced.

Use Case 1 — Autonomous Vehicle
Operational Scope
ScenarioAn autonomous vehicle developer intends to simulate pedestrian avoidance
before urban deployment.
The Simulation Object is already identified and the purpose is:
Evaluate pedestrian-avoidance behavior under selected urban operating
conditions. Application
SSCM establishes scope across:
Functional Scope: Perception, prediction, path planning, and braking.
Operational Scope: Urban driving below the defined speed threshold.
Environmental Scope: Daylight, dry conditions, and selected rain conditions.
Interaction Scope: Vehicle–pedestrian interaction.
Population Scope: Defined pedestrian behavior profiles.
Night-time operation, snow, highway driving, and vehicle-to-vehicle collision
scenarios remain outside the governed Simulation Scope. Result
Successful simulation results cannot later be represented as evidence that the
vehicle has been simulated across its complete autonomous-driving operational
envelope. Use Case 2 — Integrated Space Mission Simulation
Scenario
A space organization intends to simulate an integrated mission from launch
through orbital operation.
The initial mission program contains separate simulation environments for:
Launch
Orbital Insertion
Navigationand:
Docking Application
SSCM decomposes the broader mission scope into controlled subscopes whileidentifying the interfaces between mission phases.
The architecture detects that the transition between:
Orbital Insertion
and:Navigation
is not covered by either simulation environment.
This becomes a documented Simulation Scope
Gap. Result
The organization cannot claim complete mission simulation merely because eachmajor mission phase has an individual simulation.
The uncovered transition remains visible until governed simulation coverage is
established.
Architectural Position
Simulation Scope Module (SSCM) is the second internal governance space of theSimulation Purpose & Scope Standard (SPSS).
The internal progression begins:
Simulation Purpose → Simulation Scope
The preceding purpose module establishes:Why is the simulation being performed?
SSCM establishes:
What exactly must that simulation cover?
The next SPSS governance spaces separately govern:
what must be explicitly excluded,
where the simulation is contextually applicable,
and:
how much simulation depth and precision the intended inquiry requires.
SSCM does not replace Validation Scope under VALIDOS®, Operational Reality
governance under ORA™, Simulation Object Boundary governance under SOS, or
Reality Representation governance under RRS.
It governs specifically:
the extent of the simulation inquiry itself.
Foundational Principle
A simulation can legitimately support only the portion of the intended inquirythat falls within the scope actually governed and covered by simulation.
