SMBs have been crucial to the Colombian economy thanks to their contribution to job creation and their positive impact on production.

The sample included 100 SMBs of the textile-dressmaking sector, geographically located around the city of Medellín, Colombia, in Valle de Aburrá. To define the theoretical relationships, among categories, variables, and hypotheses, was created a path diagram as a strategy to better observe causal relationships between dependent and independent variables. To determine the instrument’s reliability, we analyzed the data using SPSS and then ran the structural equations on the LISREL software. The results allowed us to iden...
