Developing and Insight into Labour and Material Variance

The calculation of labour and material variances is not sufficient; we require knowing how the variance could have typically happened in the first place, and whether there is any connection among one causes of the variance to another. As an example: a higher price of materials could have resulted in a not favourable direct material price variance: although, because of the high quality though high priced input materials; it could have led to a favourable efficiency variance.
