    Business service represents the added value an organization delivers internally or externally. A business function groups internal behavior to support goals. A business process is a set of related internal activities with a goal of producing products/services. Processes combine activities from functions. A service describes externally visible parts of processes/functions, without showing how they are realized internally.

    Business service, business function and business process

    Question: In the business layer, the concepts business service, business function and business
    process are positioned. The exact difference between these concepts is not clear in all cases, or to be
    more exact, in practice there sometimes exists confusion if something needs to be tagged as a
    business service, a business function or a business process. In the next section we give definitions
    and descriptions of these concepts.
    Solution: A business service represents the added value that an organization delivers to its
    environment. One can make a distinction between internal and external services: Internal services
    represent the added value that is being delivered within the domain that the service belongs to.
    External services represent the added value that is being delivered to other domains or to the
    environment (for example customers).
    A business function is an area that the organization wants to pay attention to ( e.g. by putting energy
    into, structurally committing resources to etc) in order to support its business goals. A business
    function can therefore be positioned as a grouping of internal behavior based on a certain criteria (for
    example location (same department), communication, required skills, shared resources and shared
    knowledge). A business function represents a part of the added value of on organization.
    A business process is a unit of internal behavior or a collection of causal (sequence or dependency)
    related units of internal behavior, with the goal of producing a predefined collection of products and
    services. A business process can be constructed from sub processes or activities. A business
    process is triggered (started) by one or more business events or other business processes.
    Informally one could say that a business process consists of a number of activities or sub processes
    that are being executed in a certain sequence. Every activity is part of a business function. With other
    words, a process combines a chain of activities each of which are part of business functions, such as
    the figure below visualizes.

    Figure : Example of business functions in relation to processes

    A single process will not always belong to a single business function (as in this example): a business
    function will almost always consist of multiple activities and process steps and a process will often be
    realized by multiple business functions.
    Business functions as well as business processes describe the inner way of working of an area or
    organization. A business service describes the parts of business processes and functions that are
    externally visible and usable. It describes the service that can be used, without making clear how that
    service is realized by means of processes or business functions.
    In the figure below, the most important relationships between these concepts are visualized (being a
    part of the ArchiMate metamodel):

    Consequences: Not applicable.


    Alternatives: Not applicable.
    Relationships with other good practices: The distinction that exists between business service and
    business process / business function is also valid between application service and application
    function. Comparable criteria and heuristics can therefore also be used on the application layer.
