PetMed Express - Essay Example(Porter, 1985)The Force Field Analysis model defines two opposing forces acting on an plaque. The driving forces push for interpolate while the restraining forces act as a barrier for change (Falletta, 2005). To achieve the desired change, it needs to unfreeze the current state of equilibrium in an composition by adding driving forces or by eliminating restraints. Once achieved, the organization must refreeze or reestablish equilibrium. The strength of the model is its simplicity. The weakness is the surmises that disequilibrium is expected to encounter changes occur simultaneously and equilibrium will be reestablished.Leavitts Model depicts a diamond shaped model showing interdependence among four variables structure, technology, task and people. The model illustrates an assumption that changes in one variable affect the other variables. It is similar to opposing forces of the Force Field Analysis. However, the focus is within the internal environm ent of the organization and excludes the deed of the remote environment. (Falletta, 2005)Likert System Analysis addresses seven organizational variables such as motivation, communication, interaction, decision-making, goal setting, control and performance (Falletta, 2005). ... The weakness of the analysis rests on the exclusion of external environment forces that would affect the organization. The measurement also assumes independence on each level. (Falletta, 2005)The Open Systems Theory conceptualizes an organization as a social system which is babelike on the environment they work in. The theory illustrates a repeated cycle of inputs, throughputs, outputs and renewed input with a feedback loop that connects the output and renewed inputs (Falletta, 2005).Weisbords Six-Box Model follows the easy systems theory. The model illustrates six variables in an organization such as purposes, structure, relationships, leadership, rewards and helpful mechanisms. The model also identifies two management systems - formal and informal systems, which are critical to the effectiveness of an organization. The strength of the model lies on the assumption that the external environment has great influence through the organizational inputs and outputs. The model also takes into consideration the suitability of an organization to its environment. However, the model does not make any direct causal statement regarding the interconnections between variables. (Falletta, 2005)The Nadler-Tushman Congruence Model also follows the open systems theory that assumes an organization as a dynamic, open social system within a larger environment where behavior occurs at the levels of an individual, a group and the whole system. As with Weisbords model, it takes into account the formal and informal systems. The strength of the model lies on the consideration of the interaction and congruence between the individuals, group and system. The external
