5.2.2 Reliability. The reliability tests based on Cronbach’s alpha measurements were
conducted on dependent variable (i.e. role conflict) and the independent variables
(i.e. leadership, strategic planning, customer focus, human resource focus, process
management, and information analysis). As shown in Tables II and III, the reliability
coefficients ranged from 0.6316 to 0.9009, indicating that all the reliability coefficients
exceeded the minimum acceptable level of 0.6, which concurs with the criteria
suggested – “Measures of reliability that ranges from 0 to 1, with values of 0.60 to 0.70
deemed the lower limit of acceptability” (Hair et al., 2006, p. 102). Therefore, the
instrument measuring TQM practices and role conflict was assessed to be reliable
