Decision-making is always a difficult process, especially when defining an investment, management, sales, production, industrial, academic or labor project. Setting the objectives to be achieved, preparing a plan, carrying out the actions and then evaluating the results is a process that anyone can carry out and that will facilitate the decision-making process. Organizations have explicit objectives, but they are also complex systems whose decisions not only obey administrative, legal, economic standards or productivity criteria, but must also adapt to the conditions of their environment, to the capacities, competencies and abilities of their workforce of professionals and technicians, and to the physical, technological, material and other resources that they have. It is this motivation that leads us to question if the level of knowledge and application of qualitative and quantitative models is being used properly in the decision-making process of the business sector during a pandemic context in 2021. The general objective is to determine the level of knowledge of these models in the decision-making process, as well as their application, in the business sector during the COVID 19 pandemic in Peru and Chile in 2021; by relying on different specific objectives like analyzing the level of each of the knowledge dimensions of the qualitative and quantitative models mentioned for the decision-making process of the business sector and evaluating in each dimension the knowledge and application of said models in the decision-making process of that sector. The type of research was descriptive and quantitative, undergoing an analysis of the importance of good decision-making in the business sector, appropriate for a non-experimental design without the manipulation of any variables. The total number of companies was 3'995,202 as the universe for both countries, the sample size of the strata by country being 260 and 124 for Peru and Chile. Regarding the discoveries: the general alternate hypothesis is accepted, which establishes that there is not a low level of knowledge and application of qualitative and quantitative models in the decision-making process of the business sector during the COVID-19 pandemic, Peru and Chile, 2021. And lastly, it was concluded that the working hypothesis is partially accepted because it shows a trend from medium to low knowledge, that is to say 51.3% and 28.6% respectively and agrees with most of the dimensions evaluated.
