 =Types of feedback loops=
-Because system always makes circular organization, it is forming feedback loops. In many cases changing one factor will impact  another factor. This factor will again affect the first one. There are two main types of loops called positive and negative feedback loops. All loops will be explained with an example and there will be stated their dynamic behaviour.
+Because systems are always running circular in organizations, they formed feedback loops. We should state, what does the word feedback loop means exactly. In many cases changing one factor will impact  another factor (there is some affect). This factor will again affect the first one (there is some cause). Because of this it is called feedback loop.

-This loop is called a balancing or goal-seeking loop because it looks for a goal. It means if the actual state of the variable  doesn’t reach the goal the loop structure pushes its value up. On the other side if the variable is above goal, it pushes it down. An example of this loop is a thermostat which you can see on picture below. The princip of thermostat is that if is the temperature in the room higher (or lower) than is set, the thermostat increase (or decrease) the actual temperature. Another example is situation of under-resourced service company which wants to raise quality. Although better quality of services directs to improved customer satisfaction (and leads to an increase in demand), the company has not too much time for customers and this influences its  ability to improve quality. So the number of customers again decreases.  (Mind Tools Ltd, 2014) (Harich, a další, 2014).

 We can ask how the causal loop diagram is useful in practise. If we develop it and present it  carefully, it  can be very useful for us.
@@ Line 120: / Line 121: @@
 But there are other examples of great using of CLDs. CLDs can be useful in causal modelling to understand organizations and businesses. This is trend in the recent years. CLDs are  used in business prototyping, where we can model productivity and causes which influence it, e.g. remaining time, schedule pressure, deadline and so on. This causal loop diagram can be seen on picture (Transentis Consulting, 2014).

 Other examples of Causal loop diagrams are in medicine, biology or environment. We can demonstrate it on the causal loop diagram of the dynamics of diabetes. The picture and detailed description you can see in (Fonseca i Casas, 2014) or global warming system. There is a possibility to describe cases and effects of fish pond ecosystem by CLDs. PA Consulting Group created CLDs called “Afghanistan Stability / COIN Dynamics“. It is really extensive diagram summarized a snapshot of U.S. military´s plan (PA Consulting Group, 2010).
