Again, through direct contact with software professionals in events and training
courses, we got a varied sample of 127 practitioners to collect opinion on the pro-
posed list of factors of influence (see Table 4). The following sections will present
both the general descriptive results and the detailed statistical data analysis.
4.1 Descriptive Data
As a first step, a simple descriptive analysis of data is done. Percentages of respon-
dents who chose each option (i.e., confirmation of factor as a fact in professional
settings and each level of possible influence) are presented in Table 6.
