Objectives:
Article presents management functions in the context of organizational decision-making. Organizational management functions are the fundamental areas of managerial activity, allowing them to direct the work of people and resources to achieve organizational goals.

Material and methods:
The research methodology in management psychology and consumer behavior is based on rigorous social science principles, integrating quantitative, qualitative, and mixed approaches. The research is empirical in nature, requiring the operationalization of psychological constructs and basing hypotheses on falsifiable assumptions.

Results:
The research process includes identifying the problem, formulating hypotheses, selecting the sample, choosing methods, collecting data, analyzing and interpreting the results. In consumer research, ecological validity, i.e., conducting research in realistic shopping conditions, is of great importance. In management psychology, theoretical models of motivation, leadership, and organizational behavior are particularly important. Overall, the research methodology in these areas is characterized by interdisciplinarity, integrating psychology, management, marketing, statistics, and data science. This makes it possible to explain psychological mechanisms and formulate practical recommendations for organizations and the market.

Conclusions:
Making purchasing decisions is a process in consumer behavior that combines all the elements discussed earlier—perception, learning, memory, motivation, personality, and attitudes—into the final choice of a product or brand. Every day, consumers make dozens, if not hundreds, of purchasing decisions, ranging from seemingly trivial choices such as “which toothpaste to buy” to life-changing decisions about education, health, or real estate.
