The SvcV-10c Services Event-Trace Description is used to describe service functionality. It identifies service-specific refinements of critical sequences of events described in System Services.

SvcV-10c

SvcV-10c Services Event-Trace Description

One of three models used to describe service functionality. It identifies service-specific refinements of critical sequences of events described in the Operational Viewpoint.

For a detailed description see the DoDAF web site: SVcV-10c Services Event-Trace Description.

SVcV-10c Implementation

Hierarchy of system scenarios

This displays the hierarchical description of system scenarios and application system scenarios.

Scenarios for application system flow environments

An application system flow environment presents globally the flows exchanged between this application system and other application systems, systems, microservices or organizations.

To create a scenario for an application system flow environment:

1. In the navigation bar, click Services Viewpoint > SvcV-10c Services Event-Trace Description > Application System Flow Environments.

2. Click New.

3. Right-click the object created and select New > Application System Environment Scenario.

A diagram for the scenario opens.

Scenarios of application system flows

A scenario of application system flows presents the flow exchanged between the other application systems, systems or the microservices used by this application system. A scenario can represent a specific use case of this application system or, globally, the set of all flows exchanged inside this application system.

For more information search for Creating an application system structure diagram in the HOPEX IT Architecture documentation.

Scenarios of system flows

A system flow represents an information flow between systems or inside a system. It can carry content.

Content designates the content of a message or a message flow, independently of its structure. Content may be used by several messages or message flows, since it is not associated with an sender and a destination.

A scenario of system flows presents the flow exchanged between the IT services or the microservices used by this system.

See SVcV-10c System Flow Scenario Diagram.

See Defining the Subject of a Scenario.

Scenarios of systems of resources

There are different ways to edit a scenario of system of resources.

From the scenario pop-up menu you can use:

• the flow editor

• the lifeline editor

• the diagram editor

Flow editor

Lifeline editor

Diagram editor

In this scenario diagram, apart from the usual application input/output gates and application flow channels, you can find:

• IT infrastructure participants

• Hardware asset participants

System flow environments

You can create an application flow environment diagram from the system flow environment.

Scenarios of system of resources system

In this scenario diagram, apart from the usual application input/output gates and application flow channels, you can find:

• Human Asset Participants

• Hardware Asset Participants

• IT Infrastructure Participants

• System Interaction Roles

You can also edit the scenario with the flow or lifeline editor available from the scenario pop-up menu.
