Is it Really a System or just a Concept?

[Anonymous]

There are a lot of self defense systems out there. Everywhere you turn there’s a new one popping its head up with a fancy name created to strike fear in the hearts of everyone who reads them.

Fancy names aside most of these systems aren’t systems at all but just an concepts or a group of ideas put together in a presentation/demonstration format.

Before we continue, let’s look at the definition:

SYSTEM (from Latin, in turn from Greek is a set of interacting or interdependent entities forming an integrated whole.

The concept of an ‘integrated whole’ can also be stated in terms of a system embodying a set of relationships which are differentiated from relationships of the set to other elements, and from relationships between an element of the set and elements not a part of the relational regime.

Most systems share common characteristics, including:

* Systems have structure, defined by parts and their composition;
* Systems have behavior, which involves inputs, processing and outputs of material, energy or information;
* Systems have interconnectivity: the various parts of a system have functional as well as structural relationships between each other.

Process and transformation process
A system can also be viewed as a bounded transformation process, that is, a process or collection of processes that transforms inputs into outputs. Inputs are consumed; outputs are produced. The concept of input and output here is very broad. E.g., an output of a passenger ship is the movement of people from departure to destination.
