The Motivational concepts are used to model the motivations, or reasons, that underlie the design or change of some enterprise architecture. The motivation extension adds motivational concepts such as goal, principle, and requirement.

If You're a Student

Motivation elements assigned to this aspect are depicted using boxes with diagonal corners but are also color coded, indicating that it also constitutes a layer. As shown the Figure above, the main reasons for enterprise architect to adopt ArchiMate are as follows:. ArchiMate distinguishes three main Core layers:.

The ArchiMate Motivation elements enable the modeling of stakeholders, drivers for change, business goals, principles and requirements. The ArchiMate Implementation and Migration elements enable the modeling of project portfolio management, gap analysis and transition and migration planning. In the example ArchiMate model below, you can see the integration of the various ArchiMate layers. This example is comparable to the traditional information models created in the development of almost any information system. It shows the structure of the information used in the enterprise or in a specific business process or application, in terms of data types or object-oriented class structures.

Furthermore, it may show how the information at the business level is represented at the application level in the form of the data structures used there, and how these are then mapped onto the underlying infrastructure; e. This example contains the software and hardware infrastructure elements supporting the application layer, such as physical devices, networks, or system software e. It's time to get your hands dirty by drawing an ArchiMate Diagram of your own.

What is ArchiMate?

It's easy-to-use, intuitive. VP Forms New. Home Tutorials ArchiMate Diagram. What is ArchiMate? ArchiMate Tutorial The OpenGroup ArchiMate language provides a graphical language for representing enterprise architectures over time, including strategy, transformation and migration planning, as well as the motivation and rationale for the architecture.

ArchiMate distinguishes three main layers: The Business layer offers products and services to external customers, which are realized in the organization by business processes performed by business actors and roles. The Application layer supports the business layer with application services which are realized by software application components. The Technology layer offers infrastructural services e. Aspects The second dimension is made up of three aspects, which the core entities are allocated to.

Active Structure Active structures captures subjects that display actual behavior who? These active structures are represented using boxes with square corners and an icon in the upper-right corner.

Behavior Structure Behavior aspects represents behaviors of active structures how? Passive Structure Passive structures are the objects behavior is performed on what? There is no global way to visualize them with regards to the shape. Want to draw a ArchiMate Diagram?

For example if starting a process instance fails because such a constraint is violated in the output mapping in the start event of a process the incoming message is considered to be successfully delivered to the BPM engine but despite that no corresponding process instance can be found in Manage Processes of NetWeaver Administrator, i. Due to that it is advisable to avoid using data types with XSD constraints when defining the data model for the process context. Correlation Conditions Use direct value comparisons e. Parallelism BPM always locks whole context objects and not substructures of objects, so in case parallel process flows manipulate different substructures of the same context object, splitting up the object will reduce the number of access collisions.

If parallel process flows manipulate the same data structure, the access to the data structure is automatically serialized and might slow down the processing.

A data object can easily become a synchronization point, thus hamper the system performance, if it is modified from different artifacts of the process model concurrently. The same issue can appear if you mark a single activity for dynamic parallel execution par-for-each and perform an output mapping to the same data object.

Again, the execution would be serialized due to concurrent request for a write lock.

A real parallelization can be achieved by modeling an embedded sub-flow and execute this flow dynamically in parallel. Additionally, in the sub-flow you have to separate the concrete activity from the mapping to the central DO. Use an intermediate DO to store the mapping result, i. Then map the intermediate DO content to the central DO. The system will serialize the execution at the mapping activity. This means the negative impact of the serialization at the DO is less than not using a sub-process.

Operation Mappings In the process model Operation Mappings are consumed like any other service interface by assigning them to an automated activity.

Additionally, as the operation mapping is running on the local AEX of the Process Orchestration system, the service group has to point at the local system. The count of mapped attributes per activity should be smaller than fifty. Claim Check: Reducing the footprint of the process context can be achieved with the Claim Check Pattern. Error Handling The standard boundary event TechnicalError can be used to capture system errors during synchronous calls in BPM automated activities.

For the purpose of sending notifications or automated error handling activities details about the technical error are available as output fields and can be mapped to the process context.
