General Terms

The terms are arranged in the following order: the more general terms are presented first and then you see more specific ones.


Artificial object that represents a system and its components. M models the A object in case M answers some questions about A.


Active interaction of a creature (human being) with the external environment. In order to get a certain result to fulfil their needs, this human being influences the object on purpose. He/she can act by him/herself or with the help of other objects.


An activity unit selected based on a certain criterion. Activity types include Function, Process, Action, Task, etc.


An atomic activity with the exact start and end points.

Process (Business Process)

A sequence of tasks or steps taken to achieve a particular outcome. The sequence has the exact start and end points.


An activity that is a task within the parent process.


Activities grouped by a selected set of criteria. Examples of the criterion include use of same resources, functional objects, competencies, etc.


A group of humans working together in order to achieve a particular goal.

Organizational Structure

An organization model represented by composition and subordination relationships of organizational units.


A fixed state in time with zero duration, important for analysis of the modeling system.


Partitioning of an object into components.

Decomposition Diagram

A diagram used to display object components.

Process Model

A model of all possible sequences of steps from start to end events.

Function Model

A model that is the result of a function’s decomposition and describes relationships (inputs and outputs) of sub-functions.


Fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution (ISO/IEC/IEEE 42010:2011).

Business Architecture

Architecture of an organization. Business architecture includes the following elements:

  1. Objectives;
  2. Activities (processes, functions, etc.);
  3. Organizational structure;
  4. Resources;
  5. Means of production
  6. Information systems;
  7. Data.

Business Architecture Model

Work product used to express an architecture (based on Architecture Description term from ISO/IEC/IEEE 42010:2011). Work product examples include computer database, MS Excel table, diagram drawn on a sheet of paper.

Graphical Model

A model represented by shapes.

Organizational Chart

A graphical model of an organizational structure.

Process Diagram

A graphical model of a process.

Functional Diagram

A graphical model of a function.

Decomposed Process

A process that is divided into sub-processes and tasks in the Business Studio model.

Reference to Activity

An activity model element that contains a reference to an activity represented as a separate model. Reference to a reusable process can be a process task.

Reusable Activity

An activity that is an element of different activity models simultaneously, for example, a reusable process.

Reusable Process

A process that is a sub-process of different processes. A reusable process model describes the identical steps of processes for which it is a sub-process.


Movement of activity objects between activities and org units, ordered in space and time.

Process Instance

A real or simulating activity that corresponds to a process model.

Task Instance

A real or simulating activity that corresponds to a task model.
