When estimating the effect of explanatory variables on an outcome by regression, controlled-for variables are included as inputs in order to separate their effects from the explanatory variables. [1] A limitation of controlling for variables is that a causal model is needed to identify important confounders (backdoor criterion is used for the ...
Controlling is the measurement and correction of performance to make sure that enterprise objectives and the plans devised to attain them are accomplished. According to Stafford Beer: Management is the profession of control. Robert J. Mockler presented a more comprehensive definition of managerial control:
Management control as an interdisciplinary subject. A management control system (MCS) is a system which gathers and uses information to evaluate the performance of different organizational resources like human, physical, financial and also the organization as a whole in light of the organizational strategies pursued.
The exact definition varies slightly within the framework or the type of models applied. The following are examples of variations of controllability notions which have been introduced in the systems and control literature: State controllability; Output controllability; Controllability in the behavioural framework
A variable in an experiment which is held constant in order to assess the relationship between multiple variables [a], is a control variable. [2] [3] A control variable is an element that is not changed throughout an experiment because its unchanging state allows better understanding of the relationship between the other variables being tested.

Tools used for controlling and improving business processes. Tools used for data consolidation and decision making. Nowadays, management tools have evolved dramatically in the last decade thanks to fast technology advances, so fast that it is difficult to select the best business tools for any situation in any company.

In open-loop control, the control action from the controller is independent of the "process output" (or "controlled process variable"). A good example of this is a central heating boiler controlled only by a timer, so that heat is applied for a constant time, regardless of the temperature of the building.
In optimal control theory, a control is a variable chosen by the controller or agent to manipulate state variables, similar to an actual control valve. Unlike the state variable, it does not have a predetermined equation of motion. [1] The goal of optimal control theory is to find some sequence of controls (within an admissible set) to achieve ...
