O3_OSTA Operational State Viewpoint
| Domain | Aspect | Maturity |
|---|---|---|
| Operational | Process & Behavior |  under construction |
Purpose
The viewpoint defines modes of operation for the prosed system (such as normal, on-road, degraded, war-time, maintenance, training etc.) which apply not only to the SOI but also to involved personnel. An operational mode defines a potential life-cycle selection for the SOI which has a relevant impact for the SOI’s stakeholder/users w.r.t. to the operations. [tbd]
Applicability
The Operational State Viewpoint supports the “Business or Mission Analysis Process” activities of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§ 2.3.5.1] defining states/modes at an operational level (e.g., business or mission profile, and operational scenarios). The operational states/modes viewpoint contributes to Preliminary Life-cycle Concepts and the Business or mission analysis strategy.

Presentation
A block definition diagram (BDD) featuring states, and state transitions. Note: References to model elements that are dependent of states, or transitions shall be shown as callout, or compartment notation.
Stakeholder
Concern
- What operational states are defined for a system or system's operation?
- Which operational processes are possible to be performed in an operational state?
- Which operational states are possible results of performing an operational process?
Exposed Concepts
The Diagram shows the concepts exposed by the viewpoint, and related concepts if necessary.
The Table shows the concepts exposed by the viewpoint, and related concepts if necessary.
| Concept | Documentation |
|---|---|
| OPShasPreconditionOSE | Specifies the fact that the Operational Process is only provided in distinct Operational States. The states ar a precondition for the Opeational Process to be able to perform. |
| OPShasPostconditionOSE | Specifies the fact that a Operational Process can perform a particular set of transitions, possibly resulting in one of the related Operational States as a postcondition. |
| Operational State | Describes a state (or mode) of on operational level. |
| OPbeeingInOSE | Specifies that an Operational Perfomer can have certain states. Note: Of course an item is in only one distinct state at a certain time. The multiplicity means that an Item can have a set of possible states, and a state can be used to specify possible States for several operational performers. |
| Operational State Transition | Describes an allowed transition between two states on operational level. |
| triggering | Specifies that an Operational Triggering Event triggers an Operational State Transition |
