The face and content validity of the instruments were confirmed by experts, and their reliability was calculated using Cronbach’s alpha coefficient: 0.93 for organizational maturity, 0.85 for quality of work life, and 0.94 for productivity. Structural equation modeling (SEM) was used for data analysis.

Organizational maturity also had a positive and significant impact on productivity (standard coefficient = 0.44), and productivity had a positive and significant impact on quality of work life (standard coefficient = 0.38).
