Enterprise Elements | Base Elements


A structure that is relevant to the enterprise.


An object is a tangible or intangible multi-part structure such as a machine, building, application or data. Objects can have behaviour, such as performing automated activities, or support people that are doing activities. Objects consist of parts: objects that combine to form an object of a higher complexity and function.

For the purpose of enterprise design it is important to understand that not every object can be engineered and predictably (re-)produced. Some objects like machines or software applications are complicated and deterministic and can be engineered to exact specifications. Other objects like plants or social structures are complex and unpredictable and may be influenced to a certain degree only, because much of their form and function emerges through their interactions with each other and with their environment.
