The objective is to provide a multitasking methodology to study business indicators automatically using Data Science. This consists of 7 stages: data preparation, univariate analysis, bivariate analysis, grouping patterns, reduction of dimensions, supervised model training and validation. R, R-Studio (processing) and Rmarkdown (visualization) are used. The methodology is applied on four study cases (two from manufacturing sector and two from services) and provide useful information for firms and teaching-learning processes. The methodology distinguishes between media and response indicators, comprises more than 10 analysis methods, includes the three statistical scopes (univariate, bivariate and multivariate) and automatically answers six questions of interest for analysts.

Palavras-chave : Data science; business indicators; R-programming; analytics; data analysis; analysis methodology.
