What are the possible causes of an adverse material usage variance?

Intermediate

Answer

Causes include poor-quality materials (more waste/rejects), inefficient or poorly trained labor, faulty or poorly maintained machinery, incorrect (too tight) standards, theft or spillage, and design/specification changes. Identifying the cause directs the right corrective action and may reveal links to other variances (e.g., a favorable price from cheaper, lower-quality material).
Real-world example Excess scrap from a cheaper material batch explains the adverse usage variance that quarter.
