Application areas of Modelangelo
What is Modelangelo?
Modelangelo is a modeling tool for the modeling and analysis of knowledge-intensive business processes. Modelangelo is based on the method Knowledge Modeling and Description Language (KMDL®). The software Modelangelo as well as the method KMDL was developed by Prof. Dr.-Ing. Norbert Gronau and his research team of the research group Knowledge, Learning, Continuing Education at the Chair of Information Systems, Processes and Systems at the University of Potsdam.
Capture of processes for effective knowledge management in the company
In the process perspective (process view), Modelangelo enables the fast and uncomplicated recording of processes. In the knowledge perspective (activity view), knowledge can be documented and analyzed, thus laying the foundation for effective knowledge management in companies.
Individuelle Anpassungen der Modellierungssprachen
Darüber hinaus können unternehmensspezifisch Anpassungen an den Modellierungssprachen vorgenommen werden (sog. Meta-Modellierung) und eigene Modellierungssprachen graphisch, syntaktisch und semantisch definiert werden. Analysen über die erstellten Modelle können frei definiert werden. Neben KMDL kann Modelangelo auch zur Modellierung mit Ereignisgesteuerten Prozessketten (EPK und eEPK) nach Prof. Scheer genutzt werden.
Analysis of business processes
With KMDL®, Modelangelo enables an extended analysis of business processes with regard to the processing of knowledge and thus offers starting points for improving knowledge work in the company. In addition to the representation of explicit knowledge (e.g. documents and records), the tacit knowledge of the actors involved in the business process can be captured. Thus the entire knowledge base of the company can be represented, which forms the basis for a process-oriented knowledge management.
Identify potential and increase efficiency
Modelangelo enables the creation of different views of the respective process, the verification of the syntactic correctness of the models, the anchoring of the knowledge usage in the process as well as the generation of evaluations and reports. Experts can use Modelangelo to identify potentials in processes using previously defined patterns.
Functions within Modelangelo
Modelangelo has a graphical user interface. The Process Explorer integrated into the user interface displays the structure of the processes with their sub-processes and aggregations. Objects to be modeled can easily be dragged from the palette or from the Explorer into the modeling area.
While objects from the palette are considered new objects, dragging objects from the Explorer into the modeling area creates a reference to the original object. This is useful, for example, when a role occurs at multiple points in the process.
Currently Modelangelo offers the following functions:
Representation of the process flow with sub-processes
- Graphical editor for modeling knowledge-intensive business processes from a process and knowledge perspective according to KMDL®
- Refinement / Nesting of tasks

Basic functions of the Modelangelo software for process model creation using the initial user interface:
The toolbar at the top (below the menu bar) provides the most important functions. Basic functions include the creation of projects and models, their storage and export.
The modeling palette on the left side contains a selection of objects (shapes) with which processes can be created. KMDL shapes such as tasks, roles, information systems (information system e.g. MS Outlook) and objects (information object e.g. documents) can be dragged and dropped into the user interface. In the same way, the control flow for connecting tasks and the membership of roles, for example, can be selected. In addition, comments can also be created.
The overview on the lower left shows the model that has just been edited in the general view. This area can be used to navigate in large models.
4 Modeling area
The area in the middle is the workspace, here you can create and edit your process model.
Under Attributes you can define additional properties and information for your KMDL shapes. To do so, select an object, e.g. a role, and add the "+ symbol" to the properties. You can choose between Text, File Link, Web Link and Model. This enables the creation of groups, local or global variables.
6 Project Explorer
Your current project is displayed in the project folder. It is subdivided into your different models and shows the KMDL shapes you use. By clicking on an object the selected object appears on the modeling surface.
Under Properties (bottom right) you can adjust the layout and design of the selected KMDL shape. For example, name, size and color of the selected KMDL shape can be adjusted.
Terms, shapes, symbols, attributes
From the palette you can drag and drop the corresponding shapes into the modeling area. Shapes include tasks, rolls and machines.
A process is a sequence of various standardized tasks and is carried out according to defined rules. A process has different further components, e.g. interfaces to upstream and downstream processes, input, involved roles, produced and used documents (information objects) and information systems etc. For the labeling of a process nouns are used, for example "software development" or "project financing".
A task, also called process step, procedure or work step, represents a closed fact in the process. For the labeling of tasks, the default object-verb. The verb is always in the present tense, for example "test software" or "procure raw materials". In order to open up the knowledge perspective, knowledge-intensive tasks in the process can be identified and then modeled by activities in the knowledge perspective with respect to the knowledge perspective. Read more about the knowledge perspective in the modeling guide.
Linked operators and control flow
The control flow connects tasks with each other or with link operators and specifies the logical order in which the tasks are executed. The link operators can be used to represent options in the process, e.g.:
Exclusive Or (XOR) if only one of the following tasks is performed.
Logical OR, if one or more of the following tasks can be executed.
Logical AND, if all the following tasks are executed in parallel
Role (task manager)
Each task at process level is assigned at least one role, which is responsible for processing the task. No names are given, only the roles of the persons are described in which they are involved in the task in the process. Groups of persons with the department as role can also be represented, for example developers or production The assignment of one or more persons to a role can be represented by attributes.
An information system stands for the software or communication technology used in the process. From the point of view of information retrieval, an information system serves the computer-supported collection, storage, processing, maintenance, analysis, use, disposition, transmission and visualization of information. Information systems can create or process information objects (e.g. documents) by algorithms such as sorting, combining or calculating mathematical functions.
Large process models can be divided into several sub-processes; the linking of these sub-processes is done by the process interface object.
Information (e.g. documents, work instructions, invoices, recipes, standard operating procedures) is modeled as an information object and can also be the input or output of the process. Information can exist as text, drawings or diagrams on paper as well as in electronic form, in documents, audio files, bitmaps or video formats.
Physical objects, e.g. sample goods, logistics aids or tools are modeled if they are required for the purpose of the modeling.
In the age of cyber-physical production systems, a machine, such as a laser cutting machine or 3D printing unit, can also serve as an information carrier. In contrast to a physical object, machines have a component for information processing. Unlike information systems, machines also have a physical presence.
Membership means that roles, information objects, information systems and machines are assigned to a task if they are used in this task.
Attributes are information assigned to individual objects (e.g. status, number, work instruction, a link to a person's page on the intranet, a reference to a document in the document management system or a link to a function of an information system). The attributes window (bottom center) allows you to enter attributes for the selected object.

Simple process model
Start with a process interface
1. If your process to be modeled follows a previous process, you should start with a process interface. (If there is no previous process, skip this point and continue with a task).
2. Drag and drop a process interface from the palette on the left into the modeling area.
3. Give the interface a name by double-clicking the process interface and specifying the name. (here for example "Previous process")
4. Finalize the input by clicking on a location outside the process interface.
Create a task
1. Drag and drop a Task from the palette on the left into the modeling area.
2. Label the tasks with a combination of object and verb, e.g. "Send training program" or "Rate training".
Connect tasks with each other (control flow)
1. Click Control Flow in the palette on the left side. The selection is indicated by a gray background).
2. Select a task in the modeling area from which you want to start.
3. Drag the arrow from the center of the start task to the center of the target task.
4. Similarly, you can connect tasks and link operators (And, Or, Xor) with the control flow.
Optionally, you can supplement the operators' decision by clicking on the line with texts such as "Training completed" or "Training not completed".
Complete process model
Add a role (task owner)
1. Drag and drop a role from the palette on the left side into the modeling area.
2. Add at least one role to each task. These roles will be designated in a person-neutral way and not mentioned by name. You can also use a group of people (e.g. "Human Resources" or "Accounting") as a name.
Link roles with tasks (memberships)
1. Click on Membership in the palette on the left side if you want to create a new role.
2. Now click on the role that you want to associate with the task and drag the membership line from the role icon to the task icon.
Reuse the same role
If you want to reuse an existing role, drag it from the right side of the Project Explorer.
Add an information system
Drag and drop an information system from the palette on the left side into the modeling area and name the information system (in this example "MS Office" and "MS Outlook"). Other examples of information systems are "ERP", "Intranet" or "CRM".
Reuse the same system
If you want to reuse an existing information system, drag it from the right side of the Project Explorer.
Add an information object (document)
1. Drag and drop an information object (e.g. PDF document, invoice or recipe) from the palette on the left into the modeling area.
2. Label the information objects. (in the example here "training program" and "training plan")
Reuse the same document
If you want to reuse an existing information object, simply drag it from the right-hand side of the Project Explorer.
Eine Prozessschnittstelle hinzufügen
1. If your process to be modeled contains subsequent processes, add them with a process interface. (If there are no subsequent processes, skip this point and continue with a process interface).
2. Drag and drop a process interface from the palette on the left into the modeling area.
3. Give the interface a name by double-clicking the process interface and specifying the name. (here as an example "Subsequent process")
4. Finalize the input by clicking on a location outside the process interface.
Abschließen mit einem Prozessrand
1. Complete your process modeling with a process border.
To get a better overview, first zoom out to make your model smaller. This can be done either by WheelZoom using your mouse or touchpad. Alternatively, you can click several times on the magnifying glass (-) in the center of the toolbar at the top.
2. Drag and drop a process border from the palette on the left side into the modeling area.
When modeling vertically, you should insert the process boundary to the left or right of the process model. For horizontal modeling, it is best to place the process boundary above or below the process model.
3. Give the process border a name by double-clicking the process border and specifying the name (e.g. Training / Employee Qualification)
4. Click on the process border and drag it slightly larger than the process model using the green markers.
5. Select your entire process model by clicking on the process model in the upper left corner and dragging it down while holding the mouse button down. The area marked in blue represents your selection. All marked objects are displayed with a dashed outline. Click on an object of your choice of the process model and, keeping the mouse button pressed down, drag the entire process model into the process border. This appears red and then click in the process border. Your entire process model is now embedded in the process border.
6. Finalize the input by clicking on a place outside the process border
