The public policy making mostly faces challenges in choosing the right and best model. Policymakers develop disputes on various models through their ideas and theories. Mostly the model of rational decision making and incremental are disputed amongst the policy makers and economists. These both models have their own shortcomings and flaws. One is better than the other in one aspect and other is better in some other perspective. These both models have their own respective roles in shaping public policies. Despite the fact that both models have positive aspects, economists disputably argument on each model. Before going into the depth of both models, first of all, discuss their originations and their respective characteristics. One can easily distinguish them both easily looking at their characteristics. Because these both models vary from each other to a greater extent.
Instrumentalism When we talk about rational decision-making model we are considering the rational decision-making process. In which a pruritic approach toward decision making is strongly considered. This implies that the whole community desires and wants are known by the government or policymakers that these wants are calculated able and can be replaced by other alternatives by policymakers while making policies. The other aspect of the rational decision-making model is that it Denys the involvement of the community in any decision making. That means all community decision must be taken without any participation or knowing the will of the community. It focuses on efficiency achievement and net benefit. Rational model affirms that the values of the society are known and can be compensated with alternatives while making policies. This concept of a rational model closely related to the interchangeable efficiency concept. Which mean that the public can transferee their preferences from on goods to other whenever they want. The rational model also considers all social, political and economic values. Furthermore, rational decision making assumes that all decision must be on logical reasoning and rational basis. This logical reasoning consisting of four steps. The following four steps govern every decision making under the domain of the rational model.
1) Defining the goals,
2) Identifying the alternatives to achieving the goals,
3) Assessing the potential outcomings,
4) Selection the option that appears most feasible.
Whilst, on the other hand, the incremental model favors repetitive and purists based decision-making procedure. This model favors the policy-making procedure in a fragmented form, small and logical steps must be taken to finalize the policy. It counts every small step in policy formulation. Unlike the rational decision-making process, it appreciates community involvement, while the rational model is a centralized model which rejects community involvement in decision making. The incremental model was proposed by the economist Lind loom in an attempt to respond to the imperfections of the rational model. Through this model, Lind loom stated how to construct a public policy and what should be the nature of a successful public policy. In incremental model ends and means are intimately intertwined, we almost know our means of contemplating. Besides from it, few means are considered, unlike the rational model. The assumption here is that managers have limited time and resources. The degree of logic and rationality is less than the rational model. The rational model has a centerline approach whilst the incremental model has a pruritic approach in policy making procedure. Where community involvement in policy formulation is considered, in a centralized form, there is no such an involvement in policymaking. The concept of interchangeable efficiency is discussed in the rational model, whereas incremental model Denys such interchangeability.
