In addition, there are some positive and meaningful relationships between TQM components and employee performance. The highest correlation belongs to relationship between employee performance and feedback (r=4.6223, P-value=0.000) followed by training and development (r = 0.441, P-value = 0.000) and communication (r = 4.2861, P-value = 0.000).
