As part of consumer behavior, the buying decision process is the decision-making process used by consumers regarding the market transactions before, during, and after the purchase of a good or service. It can be seen as a particular form of a cost–benefit analysis in the presence of multiple alternatives. [1] [2]
The consideration set is a subset of the awareness set, which is all of the brands and products a consumer initially thinks of when faced with a purchasing decision. [2] The awareness set is filtered into the consideration set through the consumer's individual thoughts, preferences, and feelings — such as price, mood, previous experiences ...
Decision trees can also be seen as generative models of induction rules from empirical data. An optimal decision tree is then defined as a tree that accounts for most of the data, while minimizing the number of levels (or "questions"). [8] Several algorithms to generate such optimal trees have been devised, such as ID3/4/5, [9] CLS, ASSISTANT ...
The buyer decision process or consumer decision process is described in three or five stages. The basic, three stage model [3] [4] of consumption describes obtaining, consuming, and disposing of products and services. The study of consumer decision making expands these into five stages, first described by John Dewey in 1910: [5] Problem recognition
Bayesian decision theory can be applied to all four areas of the marketing mix. [11] Assessments are made by a decision maker on the probabilities of events that determine the profitability of alternative actions where the outcomes are uncertain. Assessments are also made for the profit (utility) for each possible combination of action and event.
Value tree analysis is a multi-criteria decision-making (MCDM) implement by which the decision-making attributes for each choice to come out with a preference for the decision makes are weighted. [1] Usually, choices' attribute-specific values are aggregated into a complete method. Decision analysts (DAs) distinguished two types of utility. [2]
Customer Decision Journey (CDJ): This model reflects the non-linear and iterative nature of consumer interactions. It recognizes that customers engage with brands through multiple touchpoints over time, influencing their purchasing decisions through a series of interactions and feedback loops .
The nodes and leaves can be identified from the given information and the decision trees are constructed. One such decision tree is as follows, Decision Tree branch for the information. Here the X-axis is represented as A and Y-axis as B. There are two cuts in the decision trees – nodes at 11 and 5 respective to A.
