SV-10c – Resource Event-Trace Description

Download PDF

The SV-10c provides a time-ordered examination of the interactions between resources. Each event-trace diagram will have an accompanying description that defines the particular scenario or situation.

The SV-10c provides a valuable mechanism for improving the level of detail from the initial solution design, in order to help define a sequence of interactions, and to ensure that each participating resource or resource port has the necessary information it needs, at the right time, in order to perform its assigned functionality.

Usage

The intended usage of the SV-10c includes:

  • Analysis of resource events impacting operation.
  • Behavioural analysis.
  • Identification of system requirements (input to System Requirement Document).

Product Description

The SV10c specifies, with a UML sequence diagram, the sequence in which data elements are exchanged in context of a Resource or Resource Port.

The items across the top of the sequence diagram are usages of resources or resource ports. The lifelines are depicted as vertical lines descending from the resources and ports.

Arrows between the lifelines represent exchanges of messages (data), materiel, energy or human resources. The direction of the event lines represents the flow of information from one resource / port to another. The SV-10c provides a time-ordered examination of the data elements exchanged between participating resources or system ports, and the required time interval between exchanges may be shown as a measure between the arrows. Each event-trace diagram will have an accompanying description that defines the particular scenario or situation.

The content of exchanges that connect lifelines in an SV-10c may be related, in modelling terms, with resource interactions (from, SV-1, Resource Interaction Specification, SV-3, Resource Interaction Matrix), data flows (from SV-4, Functionality Description, and SV-6, Systems Data Exchange Matrix) and data schema entities (from SV-11, Physical Schema) modelled in other views.

The interactions in SV-10c are not just limited to representing information flows. As in SV-1 and SV-4, they may also represent flows of materiel, human resources or energy.

Creating a Resource Event-Trace Description diagram

To create a Resource Event-Trace Description diagram:

  1. Click on Resource Event-Trace Description in the Action Artifact area, and then select Create New Diagram.
  2. Type the diagram name and press Enter.
  3. A blank diagram is created and you can start constructing the view.
