When a system gives same results after it has simulated repeatedly, it means that is reliable. Reliability generally means the consistency between the repeated results of an experiment or a system. But to measure reliability of a system the structure of the system should not be changed. As a result reliability generally means dependability and trustworthiness of a system.

What does significance mean?
Significance generally means importance of meaningful consequences. Another definition for significance is that significance is the quality of being significant or having a meaning.But it is generally means the real meaning of something and importance of it.
What does validation mean?
Validation is a process which determines consistency of a system or a business. To provide validation data which are predicted and which are gained after simulation should be compared. They should be consistent. Or, validation can be assessed as the act of verifying that a product or service meet the requirements for which it was intended. Validation is an important part of a system because of verification of the system.
What is waterfall diagram?
Waterfall diagram is a popular version of system development life cycle model. The waterfall method describes a linear and sequential method. This method has a distinct aim. Moreover it can not turn back like a waterfall. Waterfall development allows a managerial control and departmentalization. These are the advantages of this method. However there are some disadvanteges of these method too. For example it does not allow reflection and revision. This method can not be interfered after it designed. That is the most important disadvantage of this method.
What is snowball effect?
Snowball effect is a term for a process which is building up on itself. This process gets larger over itself. However it can be dangerous potentially. Because when it is getting larger, it will be more difficult to control it. Also when a process is getting larger, it’s the acceleration of getting larger increases too. Therefore it will be more difficult to control it. As a result snowball effect can be dangerous in business life because of uncontrolled growth.
What is a model?
A model generally means representation of something. A model sometimes can be a toy car or a person. In macroeconomics a model is designed to simulate an operation in business life. Model are tried for preventing or fixing errors. Models are also using in computer technologies too. (3D modeling). For industrial engineering, model of system is used for simulate this system and check and fix errors.

What is control?
Like planning, organizing, staffing and directing control is one of the managerial functions too. However controlling is a very important function because it helps to check errors and fix them. On the other hand controlling is important because even if there is no error in the system, there should be precaution in order to prevent forming errors. According to Henry Fayol control consists of verifying whether everything occurs in conformity with the plan adopted, the instructions issued, and principles established. It objects to point out weaknesses and errors in order to rectify them and prevent recurrence. Control also can be defined as adjust all stages of a plan and check them for specific aim. As a result, controlling is an important part of system approach and an important area of industrial engineering.
