How can variances be interdependent, and why does that matter?

Answer

Variances often interrelate: buying cheaper (favorable material price) may cause poor-quality material and adverse usage; paying higher wages (adverse rate) may buy skilled workers who are more efficient (favorable efficiency). Investigating variances in isolation can mislead—managers should consider trade-offs and root causes across related variances.
Real-world example A favorable material price bought from a cheaper supplier drives an adverse usage variance from more waste.
