Design of Experiments Applied to a Software Engineering Project Based on Knowledge Processes

The systematic application of the Experimental Design plan from Design of experiments (DoE) is presented as an essential statistical method for experimentation in Software Engineering (SE). The objective is to correctly identify the factors that influence the degree to which the externalization of knowledge is generated in a software project based on knowledge, for which a factorial design was applied with two factors (a × b). Factor A, corresponds to Project teams and factor B, is related to Externalization strategies. The effect of the factors and their interaction on the response variable (externalization of knowledge) were checked from the test statistics of the analysis of the variance ANOVA, showing that only the factor B significantly influences the externalization measurement according to the sample under study.
