1 Organizational chartData modelBPMN DiagramWhiteboardSystem landscapeBusiness processOrganizational chartData modelBPMN DiagramWhiteboardSystem landscapeBusiness processOrganizations and companies illustrate their structures withorganizational charts. With the ARIS symbolism ( Organizational unit,role and person) relationships between individual units like departmentsor employees are demonstrated. The relationships stand for:- Who is responsible for whom?- Who is the supervisor or inferior?- How are the communication channels?An organization chart quasi indicates important rules of theorganization, visible for all and clearly arranged.

2 The management andthe employees use the chart as a background for internal and data model represents the data view of a company, which business objects exist. The entity relationship notationis used for data modeling. Data models are created to define database is a process notation used to model business and workflow processes alike. BPMN is maintained by OMG. ARIS Express supports modelingof BPMN 2 collaboration BPMN collaboration diagram is used to model the interactions between participants, in a business-2-business (B2B) context. Participantsare involved in the process and represented by means of pools.

3 Interactions between these pools are represented by message flows (messageexchanges).A business process is a set of related tasks or activities performed toproduce a product or service. A business process consists of eventstriggering activities. Rules control the flow of the business process describes- which activities are performed in the course of a process,- which Organizational units participate in process execution(persons, groups of persons),- what input and output data are used,- what IT systems are involved, and- which events and risks occur during process "Person Individual persons can be assigned to an of persons: "Role Groups of persons can be combined in a role.

4 Here, twopersons are assigned to one symbol represents an event thattriggers unitUnit in an Organizational hierarchy, , a department orlocation. It can be used to show which Organizational unitsare superior to entity is an individually identifiable object ofreality. In databases, it is represented as describe what happens during aprocess, , what exactly is done. They arethe core elements of a symbol "Role" illustrates who isperforming an systemsActivities can be performed manually orautomatically. Automated activities areperformed by IT and output dataA process generates data or requires datato be able to continue.

5 These data aremodeled as input or output of InterfaceA process is not running isolated. Instead, itis embedded in a complex relationshipnetwork. Process interfaces are used toillustrate upstream and downstreamprocessesExclusive OR:Only one of the subsequent (or preceding) optionsmay rule:All subsequent/preceding paths are rule:Any number of paths can be control via rulesRules describe process workflow alternatives andthus illustrate possible execution variants. Thefollowing rule symbols are available:AttributesAttributesObjects, models, and relationships mayhave properties are called "attributes" inARIS and can be maintained in the Attributesview (main menu: View Attributes).

6 StageA "Stage" is used to gather activities andobjectives for a specific topic. You can alsodefine KPIs (Key Performance Indicators)and details for a "Activity" describes an action that has tobe performed within a following attributes can be maintained:- Name- Description/Definition- Author- Link- Multi-instance participant (BPMN diagram only)- Compensation activity (BPMN diagram only)- Loop type (BPMN diagram only)- Telephone number ( Organizational chart only)- E-mail address ( Organizational chart only)- Address ( Organizational chart only)AttributesAttributes describe properties of a data object(entity), the columns of a eventsStart events may use different symbols in BPMN.

7 For example,"Message event" for processes starting with a message, or "Timer event"for processes to be started at a specific point in systemIT systems represent logical electronic dataprocessing systems. These systems are nothardware but software systems. ERP systemsand EAI platforms can be named as keyThe primary key (here: purchase ordernumber) is a unique identifier for an keyThe foreign key is a reference to the primarykey of another data object. For example, thecustomer ID is a reference to a data object ofthe "Customer" cardinalities of relationships betweenentities illustrate the number of the example, a purchase order may includeany number of books (at least one), which isshown by the connection end symbol at the"Book" book, in turn, is assigned to any number ofpurchase orders (or none), which is shown by thezero at the "Purchase order" are set via relationship attributes(main menu: View > Attributes).

8 End eventsThese symbols mark the end of a process. You can also provideinformation on the process end, for example send a eventsThis event type is used within the process flow only; it is not used as astart or end represent decisions within the process flow. Using thecorresponding symbol, they represent parallel, exclusive, or otherexecution modesTaskIn BPMN, tasks are represented by activities. They cover thehuman ("User task" or "Manual task") or technical execution oftasks. As "Subprocesses" they represent basic and lanesThese represent Organizational pools or embedded lanes taskscan be assigned to persons or groups annotationsThey are used to add comments tomodel elementsA whiteboard model is used to record ideas and tasks and structure them the way you would do on a physical flip chartusing post-it notes.

9 A whiteboard can be created as result of a brainstorming example describes the result of a brainstorming session during which ideas concerning a product - in this case ARISE xpress - are landscapes represent the implementation options of functions and objectives via IT model shows the modular structure of IT systems and the technological properties (operating systems,user interfaces or database management systems) upon which an IT system is based. IT systems areconsidered here at type level. IT systems that are based on exactly the same technology are landscapes describe which IT systems belong to which logical units (domains).

10 This assignment information is relevant for budgeting or for defining administrative landscapeProcess landscapeA process landscape is used to structure the process portfolio of a company. Processes in a processlandscape can be connected in a sequence to describe an end-to-end scenario or a value chain. Processescan be arranged hierarchically to further refine certain process process portfolio is usually structured into the following three process types:- management processes ( strategy)- core processes ( value-adding processes)- support processes ( marketing)ProcessThis symbol represents a process that can bedescribed, by using a "Business process" symbol describes the goal thatactivities have to reach for thecorresponding stage.
