Organizational themes
Systems theory
Systems are related to each other, and they themselves contain subsystems. For definition, a system consists of a set of inputs, a set of outputs and a set of processes which transform inputs into outputs. All activities involved in the system is defined as system boundary, for example a payroll system might include all the activities in the payment of staff in a business. Others systems outside but relate to it are considered as the environment. System thinking is the interactions between the system and its environment.
A system should be looking at as a whole organization rather than separated functional subsystems. There are approaches suggest IT developers should divide complex problems into smaller issues, but they should remain it as a whole in mind because this process of decomposition may cause wrong understanding about the system or harms the unity of the system. Also, human components may react differently when we treat the system as some single processes than a role in the whole system.
According to systems theory, organizations are open systems. It means the information in the system will have two sides interaction with the environment. Also, organizations are complex systems which require a wide range of knowledge to understand, analyze and develop information systems.

There are two approaches due to systems theory. Soft systems methodology or soft thinking attempts to understand the complex organizations or real world problems. They think that systems do not exist, but they represent the complex real-world activities. On contrary, ‘hard’ approaches tends to look at the domain from one point of view only. And such systems do exist and they can be engineered.
Combining those two points of view can provide a more precise view on the real world; also it may leads to a new approach on studying systems.
