Any object (or subject) in the world can be considered as a system and any non-elementary object as a set of interdependent parts has systemic features. Any complex system can be analyzed with usage of the variety of approaches and techniques. There are several key approaches (the hard, soft and failures approaches) to system modelling and systems engineering…
These mixed approaches must be relevant for analysis of appropriate (i.e. mixed) classes of systems. Therefore, to disclose possibilities and possible disadvantages of such integral view on systems modelling, we need to consider several examples of mixed systems. Are they exist in the real world What about its properties and features Is such way of generalization in systems modelling just artless composing of existing approaches without principal innovations Or we can expect more efficiency of such generalizations
First of all, we need to note that the gap between the hard and soft approaches is more impenetrable then the gap between these ones and the failures approach. This is caused by obvious differences between hard and soft classes of systems. Indeed, hard systems are useful for problems that can justifiably be quantified. Suitable approaches involve numerical simulations and often use the techniques of operations research. Such approaches cannot easily take into account unquantifiable variables, e.g. opinions, and may treat people as being passive, rather than having complex motivations. On the contrary, soft system models are usable for systems that cannot easily be quantified. Suitable approaches can be most effective for understanding motivations, viewpoints and personal opinions, and interactions and addressing qualitative as well as quantitative dimensions of problem situations (Bode & Holstein, 2003). Thereupon Peter Checkland says: "Our experience in developing soft systems methodology is that the world is highly complex and mysterious, and far more complex than any of our ways of notating it And what I'm talking about here is the fundamental distinction between hard and soft systems thinking. The hard systems thinker takes system as in everyday language to be a label word for complexity in the world. The soft systems thinker is perfectly happy to make a conscious use of the hard systems ideas." ("Systems Practice", 2004).
However, usage of a soft systems approach to systems modelling and problem solving does not necessarily mean that hard systems approaches are no longer of value to the systemic analysts. At systems development and applications layers we can see lesser opposition then at abstract layer. For instance, while hardware engineering typically deals with just hardware and software engineering with just software, the systems engineer is responsible for seeing that the software properly operates on the hardware, and that the system composed of the two entities is capable of properly interacting with its external and often non-quantifiable environment, especially the user, while performing its intended function (Bode & Holstein, 2003). At the application layer there are no neat boundaries between hardware and software systems engineering. All the relatively neat boundaries between hardware and software systems may be violated, depending on the people and program. For example, firmware embedded into a microcontroller or a GPU is often assigned to the hardware engineer, but it is essentially a software development (as in OpenGL or DirectX applications) which is based upon interconnections with the operating system and end user.
Such cases can be considered as a shift from the well-quantifiable systems to the non-quantifiable systems which is caused by implication of unmanageable factors or unpredictable human-based subsystems. It ...

However, the discussions gravitated towards politics specifically the massive cuts in public spending as announced by British Chancellor George Osborne. The group decided to express their resistance to this policy by way of supporting corporate tax avoidance starting with a plan to occupy a Vodafone shop in Central London.
There are several OD strategies for improving the effectiveness of an organization (Falletta, 2008). The diagnostician views the whole system of an organization. The organization is looked at as system with input, throughputs, and outputs connected by feedback loops.
System thinking and systems theory assists the researchers in addressing complex problems. A system can be defined as a set of elements which are interrelated. In the case of information systems, the elements are all the users, computers (both hardware and software) and organizational processes (Dwivedi & Wade 2011).
In this regard this study is taken seriously by researchers (Hart & Gregor, 2007). The traditional concept of Information system could be viewed as a part of other systems like social, physical, and mathematical systems. Later on information system is treated as a separate system and many researches and studies are worked out for it.
Systems Theory enjoys a close relationship with Sociology as sociology has enabled systems theory to study human behaviour with the relation between the different actions of the same individual, sociology is concerned with interaction, that is with the relationship between the actions of one individual and another.
Social systems attempt to be less complex and less chaotic than the surrounding environment. It is through various elements of communication, as Luhmann et al. suggest that the systems control their boundaries. Other theories, such as exchange, dramaturgy and Marxism may also be useful within human service provisions.
The organization is looked at as system with input, throughputs, and outputs connected by feedback loops. Competitive organizations face challenges that present the need for responding with solutions to solve the
