Concept Model

Purpose: The purpose of a Concept Model is to organize an enterprise’s vocabulary to support cPonsistent and unambiguous communication about specific problem domains across business units.

Core concerns: The Concept Model template enables you to model Concepts, Specialization Aspects and Subject Areas. They can be linked by Concept Associations, Concept Aggregations, Concept Generalizations, Type Relationships, and Relationship Constraints.

You are also able to link the diagram to its area of usage through the model’s property dialogue. This area of usage can by default be set to be either an Organization Unit, Role, Actor or External Entity.

Below you can see some examples of Concept Models from a healthcare domain:

The model above shows the concepts related to the healthcare activity ‘knee arthroplasty’. The model below shows the concepts related to a signature in the healthcare domain:

The model above shows the concepts related to the healthcare activity ‘knee arthroplasty’.

The model below shows the concepts related to a signature in the healthcare domain:

Relation to other templates: A Concept Model should enable the identification of the right terms to use in communications where high precision is needed. This is useful when creating large sets of business rules or processes that need to fit together without ambiguity and when creating complex Data Models. As such, it could be advantageous to link to a concept model from the affected Business Process Networks, Workflow Diagrams, Requirements Models and Regulation Diagrams.

Properties and metadata: The Concept Model can for example retain the following information:

A description of the diagram
Link to the owner of the model
Link to the one responsible for the model
Link to view of area of usage
Audits (auto generated information regarding its current state and access rights)
Associated documents, diagrams and other objects
Inherent Risk detailing risk considerations
Governance information detailing information about the published diagram and who has been involved in the approval of the diagram

The above picture shows the properties dialogue window for the Concept Model, where you can view and edit the diagram’s properties in QualiWare Lifecycle Manager.

Composite Structure Diagram

Purpose: The purpose of the Composite Structure Diagram template is to document the internal structure of a class, Class interactions with the environment and behavior of collaborations. The Composite Structure Diagram is part of the UML version 2.5.

Core concerns: The Composite Structure Diagram enables you to model Collaborations, Collaboration Use, Properties, Classes, Interfaces and Ports. These elements can be connected by Connectors, Dependencies, Interface Realizations and Usage.

Below, you can see an example of a Composite Structure Diagram for a car safety inspection:

The Diagram shows internal structure of the Car-safety inspection class as well as the behavior of collaborations and the different classes’ interactions.

Relation to other templates: The Composite Structure Diagram is part of the UML templates QualiWare supports along with the Activity Diagram, Communication Diagram, Deployment Diagram, Class Diagram, State Diagram, Package Diagram, Component Diagram, Sequence Diagram, Use case diagram and Timing Diagram.

The Composite Structure Diagram can be defined as the components content along with the Component Diagrams, Class Diagrams, Classes, and Interfaces. The Component Object is a representation of a physical part from the system specification.

Properties and metadata: The Composite Structure Diagram can for example retain the following information:

A description of the diagram
Link to the owner of the diagram
Link to the one responsible for the diagram
Extensions (Stereotypes, constraints and tagged values)
Audits (auto generated information regarding its current state and access rights)
Associated documents, diagrams and other objects
Inherent Risk detailing risk considerations
Governance information detailing information about the published diagram and who has been involved in the approval of the diagram

The above picture shows the properties dialogue window for the Composite Structure Diagram where you can view and edit the diagram’s properties in QualiWare Lifecycle Manager.

For more information: about the UML, please visit the Object Management Group’s Website, where you can find the complete specification.

Component Diagram

Purpose: The purpose of the Component Diagram is to specify the structure of and dependencies among the different components that make up a system.

Core concerns: The Component Diagram template enables you to model a system’s Components, Classes, Interfaces, Packages, Artifacts and Ports. They can be connected by Dependency, Interface Realization, Component Realization, Usage, Generalization or a generic Connector. Below, you can see an example of a simple Component Diagram consisting of Components connected by Dependencies.

Using the properties dialogue, you can identify extensions such as Stereotype, Constraints and Tagged values:

Relation to other templates: The Component Diagram is part of the Application domain and shows how a system is structured. To model how users interact with a system you should use a Use Case Diagram, to model how interactions with the system through processes you should use the Sequence Diagram template. To model the structure of an application landscape you should use the Application Architecture Diagram.

Properties and metadata: The Component Diagram can for example retain the following information:

A description of the diagram
Link to the owner of the diagram
Link to the one responsible for the diagram
Audits (auto generated information regarding its current state and access rights)
Associated documents, diagrams and other objects
Inherent Risk detailing risk considerations
Governance information detailing information about the published diagram and who has been involved in the approval of the diagram

The above picture shows the properties dialogue window for the Component Diagram where you can view and edit the diagram’s properties in QualiWare Lifecycle Manager.

Communication Diagram

Purpose: The purpose of the Communication Diagram template is to document interactions between objects or parts, focusing on sequenced messages.

Core concerns: The Communication Diagram template is a simplified UML 2.0 alternative to the UML Collaboration Diagram. It enables you to model Lifelines and Annotation, which can be connected by messages.

Below you can see a simple example of a Communication Diagram:

Relation to other templates: Usually, Communication Diagrams would be modeled using information from Class Diagram, Sequence Diagram, and Use case diagram. It is related to the other UML interaction diagrams: Sequence Diagram, Interaction overview diagram and Timing Diagram.

While the Communication Diagram show much of the same information a Sequence Diagram does, the Communication Diagram conveys which elements each one interacts with better, while sequence diagrams show the order in which the interactions take place more clearly.

Other UML diagrams that QualiWare support include: Activity Diagram, Communication Diagram, Deployment Diagram, , Composite Structure Diagram, State Diagram, Package Diagram, Component Diagram, Composite structure Diagram, and Object Diagram.

Properties and metadata: The Communication Diagram can for example retain the following information:

A description of the diagrams
Link to related sequence diagram
Extensions (Stereotype, Constraints and Tagged values)
Audits (auto generated information regarding its current state and access rights)
Associated documents, diagrams and other objects
Inherent Risk detailing risk considerations
Governance information detailing information about the published diagram and who has been involved in the approval of the diagram

The above picture shows the properties dialogue window for the Communication diagram, where you can view and edit the diagram’s properties in QualiWare Lifecycle Manager.

For more information: about the UML, please visit the Object Management Group’s Website, where you can find the complete specification.

Class Diagram

Purpose: The primary objective of the Class Diagram template is to visually represent and document the structural components of a system utilizing the Unified Modeling Language (UML). Displayed below is an example of a straightforward Class Diagram:

Core concerns: The Class Diagram effectively captures the various classes within a system, their attributes, operations, and the relationships between classes and other objects, such as packages. This comprehensive representation enables a clear understanding of the system’s structure, promoting efficient communication among stakeholders and facilitating system design and maintenance.

Example: In the Class Diagram below, the relationships between the classes “Customer” and “Internet User” and the packages “WEB-API”, “Reservation Control”, “GUI” (Graphical User Interface), and “Database” are illustrated. This example highlights the connections among different components and provides a visual overview of how they interact within the system:

Relation to other templates: The Class Diagram presents a detailed structural view of information. It can for example be a decomposition of an Information System which typically is presented in an Application Architecture Diagram. If a Class Diagram becomes too complex or large, a Package Diagram, where the classes are grouped into Packages, could be modelled instead.

Properties and metadata: The Class Diagram can for example retain the following information:

A description of the diagram
Link to the owner of the diagram
Link to the one responsible for the diagram
Audits (auto generated information regarding its current state and access rights)
Extensions regarding constraints and tagged values
Associated documents, diagrams and other objects
Inherent Risk detailing risk considerations
Governance information detailing information about the published diagram and who has been involved in the approval of the diagram

In the picture below you can see the Class Diagrams properties dialogue window, where the information can be viewed and edited:

Business Process Diagram

Purpose: The purpose of the Business Process Diagram template is to enable workflow modelling using the industry standard BPMN (Business Process Modeling Notation).

Core concerns: The Business Process Diagram template supply you with the BPMN icons that enable you to draw a workflow diagram. These icons include different types of events, activities, gateways, connectors, as well as pools, lanes and artifacts such as data objects and messages. The Business Process Diagram is typically used to illustrate business processes and software processes used in requirement documentation. Below is an example of a classic BPMN diagram with swimlanes:

To ensure the right BPMN syntax, the Business Process Diagram template will continuously perform Graphic Syntax Checks while you model. When a graphic syntax error occurs, you will be met with an error message like the one shown below:

Other functionalities: The Business Process Diagram can enable the execution and automation of a process when the diagram is converted into XML type files.

If you don’t wish to have a visible pool in your diagram, you can choose to have a ‘default pool’ that doesn’t have to be graphically represented. You can see an example of a diagram without pool and lanes below:

Relation to other templates: The Business Process Diagram template is exclusively aimed at modeling using the BPMN standard. If the BPMN is not chosen as a mandatory standard, the WorkFlow Diagram template, which has fewer syntax limitations, can be used instead.

The Business Process Diagram is typically linked as a decomposition of a Business Process contained in a Business Process Network template.

Properties and metadata: The Business Process Diagram can for example retain the following information:

Description of the diagram
Expression and query language
Link to the owner of the process
Link to the one responsible for executing the process
Audits (auto generated information regarding its current state and access rights)
Associated documents, diagrams and other objects
Inherent Risk detailing risk considerations
Governance information detailing information about the published diagram and who has been involved in the approval of the diagram

In the picture above you can see the Business Process Diagram’s properties dialogue window, where the diagram’s properties can be viewed and edited:

Architecture Framework

Purpose: The purpose of the Architecture Framework template, is to provide an overview of the enterprise, and the context for a diagram, showing where in the architecture and repository it belongs. An Architecture Framework shows the overall structure of the architecture and the structure with which it is represented in the repository.

Core concerns: The Architecture Framework template consists of FrameWorkCells, FrameWorkColumns, FrameWorkRows and LineOfBusinesses. You can choose to model the framework to fit the one your organization is using – QualiWare supports a wide range of architecture frameworks out of the box such as Zachman, TOGAF , OIOEA, EA3 Cube, EDGY, QualiWare EA Framework, and many more.

Below, you can see an example of the QualiWare EA Framework:

Below, you can see an example of a TOGAF framework:

Relation to other templates: The Architecture Framework template is used to represent the repository’s architecture in the form of a specific framework. If CXO dashboards are to be created, the Strategy Model should be used instead.

An ArchitectureFramework can be modeled using FrameWorkRows, FrameWorkColumns, and FrameWorkCells

Properties and metadata: The Architecture Framework can for example retain the following information:

A description of the diagram
Link to Architecture principles and project models
Link to the owner of the framework
Link to the one responsible for the framework
Audits (auto generated information regarding its current state and access rights)
Associated documents, diagrams and other objects
Inherent Risk detailing risk considerations
Governance information detailing information about the published diagram and who has been involved in the approval of the diagram

The above picture shows the properties dialogue window for the Architecture Framework where you can view and edit the diagram’s properties in QualiWare Lifecycle Manager.

Application Platform Viewpoint : ArchiMate

Scope: Multiple layer/Multiple aspect

Shows structure of a typical application platform and how it relates to supporting technology.

Application Usage Viewpoint : Archimate

Purpose: Designing, deciding

Concerns: Consistency and completeness, reduction of complexity

Scope: Multiple layer/Multiple aspect

The application usage viewpoint describes how applications are used to support one or more business processes, and how they are used by other applications. It can be used in designing an application by identifying the services needed by business processes and other applications, or in designing business processes by describing the services that are available. Furthermore, since it identifies the dependencies of business processes upon applications, it may be useful to operational managers responsible for these processes.

Abstraction Level
Coherence

Layer
Business and application layers

Aspects
Behavior, active structure, passive structure

Application Cooperation Viewpoint : Archimate

Concerns: Relationships and dependencies between applications, orchestration/choreography of services, consistency and completeness, reduction of complexity
Purpose: Designing
Scope: Multiple layer/Multiple aspect

The application cooperation viewpoint describes the relationships between applications components in terms of the information flows between them, or in terms of the services they offer and use. This viewpoint is typically used to create an overview of the application landscape of an organization. This viewpoint is also used to express the (internal) cooperation or orchestration of services that together support the execution of a business process.
