Engel Kollat Blackwell Model of Consumer Behaviour

Introduction of Engel Kollat Blackwell Model

First developed in 1968, the EKB model of consumer behaviour was originally designed to save as framework for organizing the fast-growing body of knowledge concerning consumer behaviour. This model talks of consumer behaviour as a decision process in the form of four steps activities and other related variables which occur over a period of time. The Engel Kollat Blackwell model is essentially a conscious problem solving and learning model of consumer behaviour.


Concept of Engel Kollat Blackwell Model

The Engel Kollat Blackwell Model of consumer behavior was created to describe the increasing, fast growing body of knowledge concerning consumer behaviour. This model. Like in other models, has gone through many revisions to improve behaviour. This model, like in other models has gone through many revisions to improve its descriptive ability of the basic relationship between components and subcomponents.

Define Engel Kollat Blackwell Model

It is developed in 1968. The EKB of consumer behaviour was originally designed to save as framework for organizing the fast-growing body of knowledge concerning consumer behaviour. EKB model is problem solving and learning model of consumer behaviour.
  1. The Engel Kollat Blackwell Model, also referred to as the EKB model was proposed to organize and describe the growing body of knowledge and research concerning consumer behaviour.
  2. A comprehensive model it shows the various components of consumer decision making and the relationship or interactions among them.

Applicability and steps of EKB Model

This model applies to businesses that have many competitors with similar products or service. If your product market is highly saturated and competitive, the goal is to outshine your competitors by meeting customers at every stage of their journey.

Steps of EKB Model

The Blackwell model “used concepts of behavioral science in an attempt to model, in a way both detailed and capable of general applications, the process which the consumers must go through in decision.” This model is designed to show the development in the amount of knowledge in customer’s behaviour. 

In the model there are five stages, this involves problem recognition, alternate evaluation, search for alternatives and purchase and outcomes. It is not essential for the customers to go through all those stages. The customers would get data from marketing and non-marketing research; this would influence the problem recognition. This is the first stage of the decision-making process for the customer. If the customers have still not come to a final decision, the consumer would go to the next stage of the Blackwell model.

The EKB model of consumer behavior was originally designed to save as framework for organizing the fast-growing body of knowledge concerning consumer behavior. Like Howard Sheth model it has gone through a no. of revision aimed at improving its descriptive ability & clarifying basic relationship between component & sub component.

  1. Problem Recognition – The process begins when consumers perceive a need or a problem that needs to be solved. This could be triggered by internal factors such as hinger or thirst and external factors such as advertising or recommendations from friends. 
  2. Information Search – once consumers recognize a problem, they actively seek information to help them make a decision. This information can be gathered from various sources including personal experiences, word of mouth recommendations, advertisements and online reviews.
  3. Evaluation of Alternative – After gathering information, consumers evaluate the available options based on various criteria such as price, quality, brand reputation and features. They compare the different alternative to determine which one best meets their needs and preferences.
  4. Purchase decision – once consumers have evaluated the alternatives, they make a decision to purchase a particular product or service. This decision is influenced by factors such as the perceived value of the product, affordability and availability.
  5. Post purchase evaluation – After making a purchase, consumers evaluate their decision and the products performance. If the product meets or exceeds their expectations, they are likely to experience satisfaction and may become repeat customers. However, if the product fails to meet their expectations, they are may experience dissatisfaction and may not purchase from the same brand in the future.
