Integration and Differentiation

Systems integration and differentiation describes a dynamic interplay between a the whole of a system and it parts through which evolutions can occur

Systems integration and differentiation describes a dynamic interplay between the whole of a system and it parts

Integration and differentiation represent two different stages during the evolution of a system. Differentiation is the process whereby an integrated system becomes divided up into more specialized, well-defined parts. Integration is the process whereby diverse elements become combined or synthesized into a whole system. The process of evolution involves a dynamic interplay between systems differentiation, where new different elements are created, and systems integration where those elements that are best suited to the whole system are selected by the environment as the system becomes reintegrated.

Differentiation

Differentiation means the process of becoming or making something different.1 Differentiation involves a process of disintegration, the dividing up of an integrated system into more specialized subsystems.2 Through the process of differentiation what was originally a homogenous system becomes heterogeneous as its constituent subsystems come to form their own identity and structural features that are distinct from each other. Differentiation enables specialization. The formation of separate individual subsystems enables those components to focus more intensely on a particular function or activity. Thus allowing them to become more efficient at this activity than if they had to perform a large number of diverse activities. System differentiation is likewise a structural technique for solving the temporal problems of a system situated in a complex environment.3 System differentiation is understood within systems theory as a way of responding to and dealing with the complexity of the system’s environment. This is accomplished through the creation of subsystems in an effort to copy within a system the difference between it and the environment. The differentiation process is a means of increasing the complexity of a system since each subsystem can make different connections with other subsystems. It allows for more variation within the system to respond to variation in the environment.4

Examples of Differentiation

The development of modern societies into many different specialized institutions from what were largely homogeneous organizations within pre-modern societies is an often cited example of differentiation. One of the central ideas of the systems sociologist Niklas Luhmann was that modern society is differentiated into various self-referential functional subsystems which operate according to their own particular logic without being subordinated to a central unit. They are open for exchange with each other but also interdependent being largely responsible for their own functioning and development.5 Biological differentiation is the process by which cells or parts of an organism change during development to serve a particular function. For example, the cells of an animal in its early embryonic phase, are identical at first but develop through differentiation into specific tissues, such as bone, heart muscle and skin.6

The development of a child into an adult is a process of differentiation as the child become separated from the family unit and forms its own separate identity.

The development of a child into an adult is a process of differentiation as the child becomes separated from the family unit and forms its own distinct identity.

Differentiation within a material is any process in which a mixture of materials separates out partially or completely into its constituent parts, as in the cooling and solidification of a magma into two or more different rock types or in the gradual separation of the originally homogeneous earth into crust, mantle, and core.7 Likewise within economics, product differentiation is a marketing process that showcases the differences between products. Differentiation looks to make a product more attractive by contrasting its unique qualities with other competing products.8

Integration

Systems integration involves the interrelating and recombining of differentiated parts. Systems integration is the composition of a whole functioning system by assembling elements in a way that allows them to work together to achieve an intended purpose.9 In engineering, for example, system integration is defined as the process of bringing together the component subsystems into one system and ensuring that the subsystems function together as a whole system.10 Integration requires the development of new layers of abstraction that can accommodate the diversity of the differentiated components it is designed to interrelate. Integration involves the development of a generic layer to integrate the differentiated elements. For example, to enable the development of a new level of socio-economic organization in the form of globalization it is required that we develop some language through which the different societies can interoperate.
This integration process through which a new, more abstract, level of organization combines the elements also works to reduce their autonomy, in order to align them with the functioning of the whole system. For example, the formation of the political entity of the European Union enables interoperability between the differentiated countries but likewise constrains their national governments, to some extent.

In the paper “A Complexity Drain on Cells in the Evolution of Multicellularity” Daniel McShea describes this process in living organisms as such: “In evolution, as higher-level entities arise from associations of lower-level organisms, and as these [higher level] entities acquire the ability to feed, reproduce, defend themselves, and so on, the lower-level organisms will tend to lose much of their internal complexity.”11 Integration both constrains and enables differentiation. Cells in multicellular organisms can rely on the whole organism adapting to changing conditions via a multicellular response. Thus the individual cells can do away with the rarely used functions to become more specialized and differentiated. Social insects demonstrate the same sort of tradeoff “individuals of highly social ant species are less complex than individuals from [socially] simple ant species.”12 But it is the complex social interaction – the integration –  between them that allows them to perform, as a whole, more effectively.

Differentiation and integration enable and create each other, integration can only take place when there are different parts. Likewise, differentiation can only occur through integration into a larger organization; because elements that remain autonomous are required to perform multiple functions to maintain themselves within their environment. Differentiation thus actually becomes the basis for any form of unity, since the unity of any (sub)system can only be based on its difference from its environments.13 A central part of an evolutionary process of development is a dialectic interplay between a system’s macro level – integration into the whole – and micro level – differentiation of the parts. This process of development can be understood as a form of dialectic change.15View Source'>14 It is the dynamic interaction between the process of integration and differentiation that drives the evolutionary process of development within the system in a dialectic form. Homogenous systems divide, define their difference, compete and then reintegrate into a more complex whole.

  14. View Source/note] A dialectic process of development implies a division of some whole into parts whereby these parts then compete before being reintegrated through a synthesis. Expressed in everyday language, the idea of the dialectic implies a movement back and forth. The movement goes right, then left, then right again, and so on, but the overall direction is straight ahead. The dialectic is an exchange with one force or phenomena being counter-acted by another, the result being a dynamic interplay until a synthesis is formed.16View Source
