Adapted from Figure 1 in McGrath,p. Her punctuated equilibrium model Gersick, suggests that groups develop through the sudden formation, maintenance, and sudden revision of a "framework for performance". This model describes the processes through which such frameworks are formed and revised and predicts both the timing of progress and when and how in their development groups are likely, or unlikely, to be influenced by their environments. The specific issues and activities that dominate groups' work are left unspecified in the model, since groups' historical paths are expected to vary.
Theories Scientific studies and discoveries come about after a well-thought-out hypothesis and thoroughly conducted experiments that produce models and theories. Students may encounter countless models and theories of famous scientists who once aimed to explain the different phenomena.
The definitions of the two terms can be confusing. Students may come up with both models and theories after performing the step-by-step process of scientific methods; however, models and theories are produced in different periods and levels of the study.
Models may be produced after the formulation of theories, but there can be instances where the models are produced before the theories.
There can also be cases when models produce theories that in turn lead to the construction of another model for the verification of a theory. Note that one difference relies upon the fact that models are the basis of theories, while theories are the main basis for the explanation of different phenomena.
Models come in the form of a verbal, visual, or mathematical representation of a prospect or scientific process of structure that should be followed by scientists in order to come up with theories and test inferences. They can then be formulated after conducting extensive observations of physical phenomena.
When scientists have come up with a model showing structures of the scientific method, repeated experiments following the model will be conducted in order to come up with acceptable theories. In some instances, models can also be seen as an application of theories.
They consist of a given group of boundary conditions that serve as a projected possibility based on the premises of a certain theory.
When the behavior of the Eiffel Tower during an earthquake is being observed, for example, a computer simulation may show the possible movements based on what the Prandtl-Meyer stress-strain relationship theory implies.
In this scenario, models result from what theories state instead of the other way around.
Models can also be defined as a physical representation of a theory. A scientist studying the behavior of ants in a colony, for example, can have set theories on how the ants gather and store food. Observation of ants in their natural habitat may be difficult, and he will feel the need to devise a physical model, which may take the form of an ant colony inside a glass box.
As the scientist observes the behaviors of the devised model, theories can then be confirmed, rejected, restated, or changed. Physical models can, therefore, be a tool for the verification of the theory. Simply put, both a model and a theory state possibilities and provide explanations for natural phenomena.
Models can be used in the formulation of experimental setups as the scientist performs the steps of the scientific method. They give structure for the formulation of theories. Models may also serve as the representation of possibilities with respect to the premises of theories; scientists can create simulations and formulate hypotheses modeled after the theories.
In some cases, models can also be used to confirm a theory. Models and theories provide possible explanations for natural phenomena. Models can serve as the structure for the step-by-step formulation of a theory. Theories can be the basis for creating a model that shows the possibilities of the observed subjects.
Models can be used as a physical tool in the verification of theories.

Models can be described as theories with a more narrowly defined scope of explanation; a model is descriptive, whereas a theory is explanatory as well as descriptive [ 29 ]. add logo here Douglas McGregor Lesson 2: Different Theories and Models Of Organizational behavior Theory-* Homans:"in its lowest form of classification is a set of pigeon holes, a filing cabinet in which facts can urbanagricultureinitiative.comg is more lost than a loose fact.".
