Some Actions can be executed by Digital Actors
Traditionally, Actions were executed by Human-Actors.
But, since the arrival of programmable machines, a growing part of the Actions is executed by these machines which we refer to as "Digital Actor" or "IT-Actor" for short.
They are workstations, servers, smartphones, tablets or any "programmable" object (or rather one that is "intelligent") that can be incorporated in Goods today.
We often combine the Human-Actor and the IT-Actor to increase the capability of the Human Actor.
Using the "Human-Actor" and "IT-Actor" terms may not please some people who do not want us to be able to associate a human being with a machine. But the use of the word "Actor" to represent the one who executes the Actions is used in order to show that the Actions of a same business process can be executed by one or the other. That certain Actions are taken into account by IT-Actors relieves the Human-Actors of Activities with little added value, which enables them to focus on more noble tasks.
In any case, an IT-Actor can only execute the Actions for which it has been programmed by the Human-Actor. The IT-Actor cannot decide or invent or innovate, but it can be a good tool to accompany the Human-Actor in his or her tasks.
The Human-Actor is an autonomous social system with his/her own objectives (like an enterprise) whereas the IT-Actors are not autonomous and do not have any objectives. This leads to constraints and different results in the use of these resources: as an example, we have to give meaning to a Transformation so that the Human-Actors will accept it, whereas the IT-Actors do not have to accept it.
The IT-Actor Model is software
Procedure and software are the Models that the Actor must follow.
A procedure is a list of instructions for the Human-Actor to carry out his/her activity properly. For example, a recipe contains the list of ingredients and the list of actions to execute with these ingredients. It is an Information Model (the ingredients) and an Action Model (the list of Actions).
The list of instructions for the IT-Actor is called software: it also includes its Information Model and its Action Model. Software is nothing more than a Model.
