Decision-making is a cognitive process that results in the selection of a course of action among several alternative scenarios.

Open and closed systems in social science

A system is commonly defined as a group of interacting units or elements that have a common purpose. The units or elements of a system can be cogs, wires, people, computers, and so on. Systems are generally classified as open systems and closed systems and they can take the form of mechanical, biological, or social systems. Open systems refer to systems that interact with other systems or the outside environment, whereas closed systems refer to systems having relatively little interaction with other systems or the outside environment.

For example, living organisms are considered open systems because they take in substances from their environment, such as food and air and return other substances to their environment. Humans, for example, inhale oxygen out of the environment and. Similarly, some organizations consume raw materials in the production of products and emit finished goods and pollution as a result.

In contrast, a watch is an example of a closed system in that it is a relatively self-contained, self-maintaining unit that has little interaction or exchange with its environment. All systems have boundaries, a fact that is immediately apparent in mechanical systems such as the watch, but much less apparent in social systems such as organizations.

The boundaries of open systems, because they interact with other systems or environments, are more flexible than those of closed systems, which are rigid, and largely impenetrable.

A closed system perspective views organizations as relatively independent of environmental influences. The closed systems approach conceives of the organization as a system of management, technology, personnel, equipment, and materials, but tends to exclude competitors, suppliers, distributors, and governmental regulators.

This approach allows managers and organizational theorists to analyze problems by examining the internal structure of a business with little consideration of the external environment. The closed-system perspective basically views an organization much as a thermostat; limited environmental input outside of changes in temperature is required for effective operation.

Once set, thermostats require little maintenance in their ongoing, self-reinforcing function. While the closed-system perspective was dominant through the s, organization scholarship and research subsequently emphasized the role of the environment. Up through the s, it was not that managers ignored the outside environment such as other organizations, markets, government regulations, and the like, but that their strategies and other decision-making processes gave relatively little consideration to the impact these external forces might have on the internal operations of the organization.

Open systems theory originated in the natural sciences and subsequently spread to fields as diverse as computer science, ecology, engineering, management, and psychotherapy. In contrast to closed systems, the open system perspective views an organization as an entity that takes inputs from the environment, transforms them, and releases them as outputs in tandem with reciprocal effects on the organization itself along with the environment in which the organization operates.

That is, the organization becomes part and parcel of the environment in which it is situated and initiates feedback mechanisms to the results achieved by the outputs of the organization on the environment. As an open-systems approach spread among organizational theorists, managers began incorporating these views into practice.

Two early pioneers in this effort, Daniel Katz and Robert Kahn, began viewing organizations as open social systems with specialized and interdependent subsystems and processes of communication, feedback, and management linking the subsystems. Katz and Kahn argued that the closed systems approach fails to take into account how organizations are reciprocally dependent on external environments. For example, environmental forces such as customers and competitors exert considerable influence on corporations, highlighting the essential relationship between an organization and its environment as well as the importance of maintaining external inputs to achieve a stable organization.

Furthermore, the open systems approach serves as a model of business activity; that is, business as a process of transforming inputs to outputs while realizing that inputs are taken from the external environment and outputs are placed into this same environment. Companies use inputs such as labor, funds, equipment, and materials to produce goods or to provide services, and they design their subsystems to attain these goals.

These subsystems are thus analogous to cells in the body, the organization itself is analogous to the body, and external market and regulatory conditions are analogous to environmental factors such as the quality of housing, drinking water, air, and availability of nourishment.

The production subsystem, for example, focuses on converting inputs into marketable outputs and often constitutes a primary purpose of a company. The boundary subsystem's goal is to obtain inputs or resources, such as employees, materials, equipment, and so forth, from the environment outside of the company, which are necessary for the production subsystem.

This subsystem also is responsible for providing an organization with information about the environment. This adaptive subsystem collects and processes information about a company's operations with the goal of aiding the company's adaptation to external conditions in its environment.

Another subsystem, management, supervises and coordinates the other subsystems to ensure that each subsystem functions efficiently. The management subsystem must resolve conflicts, solve problems, and allocate resources, and so on.

The task environment includes customers, suppliers, competitors, employees, and regulatory bodies. Furthermore, in contrast to closed-systems, the open-system perspective does not assume that the environment is static. Instead, change is the rule rather than the exception.

Consequently, investigation of environmental stability and propensity to change is a key task of a company, making the activities of an organization contingent on various environmental forces. As an open system, an organization maintains its stability through feedback, which refers to information about outputs that a system obtains as an input from its task environment.

The feedback can be positive or negative and can lead to changes in the way an organization transforms inputs to outputs. Collier and Agyei-Ampomah point out that feedback data enable open system organizations to determine the impact of their inputs in the environment and the subsequent action for either maintaining positive impacts or correcting negative impacts. The difference between closed systems and open systems, then, lies in the complexity of environmental interactions.

Closed systems exhibit minimal interaction with the environment because of their tightly guarded and relatively impenetrable boundaries. Consequently, very little information exchange takes place between the organization and the environment in closed systems, a situation that denies management the opportunity to receive feedback from the environment. Moreover, closed systems are generally static and do not provide room for multiple alternatives for accomplishing the same result.

Conversely, open systems such as the human body and modern organizations are more intricately dependent on their environments. Organizations that observe open systems management design their operational strategies along the principles of continuous information exchange, continuous target market evaluation, and multiplicity of alternatives for achieving the same goal.

The point is that closed systems and open systems represent a continuum along which organizations are more open or less open to their environments. The key defining variable governing this degree of openness is the complexity of the environment in which the organization is situated.

Managers must take into consideration their organization's position along the open-closed continuum. The Linux computer operating system, for instance, is open-source, and Red Hat, Inc. Chesbrough, Henry W. Boston: Harvard Business School Press, Collier, Paul, and Samuel Agyei-Ampomah.

5 decision-making models to try if you’re stuck

Ludwig Bertalanffy describes two types of systems: open systems and closed systems. The open systems that we know of are systems that allow interactions between their internal elements and the environment. Equilibrium thermodynamics, for example, is a field of study that applies to closed systems. The idea of open systems was further developed in systems theory. In social sciences , schematically, if there is an interaction or feedback loop between ideal and material or subjective and objective then the system is an open system, otherwise it is a closed system.

Open and Closed Systems

The closed and open model approach to the study of public administration focuses on the organization itself. One way to study complex organizations is to view them as an open or a closed system. Before we try to understand the open and close system with respect to the study of public administration in general and organizations in specific, let us make an effort to know what an open and a closed system are.

Вы позволите поговорить с вами об. Беккер заколебался. - Видите ли, я, честно говоря, очень спешу.  - Он надеялся, что отказ представителю самого мощного разведывательного ведомства не слишком большая глупость с его стороны, но партия в сквош начиналась через сорок пять минут, а он дорожил своей репутацией: Дэвид Беккер никогда не опаздывает на партию в сквош… на лекцию - да, возможно, но на сквош -. - Постараюсь быть краткой, - улыбнулась Сьюзан Флетчер.  - Пожалуйста. Через десять минут Беккер уже сидел в буфете АНБ, жуя сдобную булку и запивая ее клюквенным соком, в обществе очаровательной руководительницы Отделения криптографии АНБ.

Севильский собор, подобно всем великим соборам Европы, в основании имеет форму креста. Святилище и алтарь расположены над центром и смотрят вниз, на главный алтарь. Деревянные скамьи заполняют вертикальную ось, растянувшись на сто с лишним метров, отделяющих алтарь от основания креста.

Казалось, что с той минуты, когда рано утром ему позвонил Стратмор, прошла целая вечность. Сдвинув в сторону пустые пивные бутылки, Беккер устало опустил голову на руки. Мне нужно передохнуть хотя бы несколько минут, - подумал. В нескольких милях от этого места человек в очках в железной оправе сидел на заднем сиденье фиата, мчавшегося по проселочной дороге.

Еще пара секунд, и его соединили с больничным офисом. Наверняка сегодня к ним поступил только один канадец со сломанным запястьем и сотрясением мозга, и его карточку нетрудно будет найти. Беккер понимал, что в больнице не захотят назвать имя и адрес больного незнакомому человеку, но он хорошо подготовился к разговору. В трубке раздались длинные гудки.

 Вот тут-то вы и рассмотрели его кольцо. Глаза Клушара расширились. - Так полицейский сказал вам, что это я взял кольцо.

Управлять всей информацией в мире. И ТРАНСТЕКСТ больше не нужен. Никаких ограничений - только свободная информация. Это шанс всей вашей жизни. И вы хотите его упустить.

Солнечные лучи, проходя сквозь этот экран, покрывали стены нежным кружевным узором. Крошечные частички пыли, пленницы мощной системы деионизации купола, простодушно устремлялись вверх широкой спиралью. Наклонные стены помещения, образуя вверху широкую арку, на уровне глаз были практически вертикальными.

 Несколько недель назад, когда я прослышал о том, что Танкадо предложил выставить Цифровую крепость на аукцион, я вынужден был признать, что он настроен весьма серьезно.
