Definitions:

Direct Material Standards

Established benchmarks for the cost and quantity of materials required for production processes.

Direct Material Price Variance

Direct material price variance is the difference between the actual cost of materials used in production and the expected (or standard) cost, indicating how effectively a company manages its resource costs.

Actual Production

Refers to the quantity of goods that have been produced within a given time frame, as opposed to planned or theoretical production levels.

Direct Labour Variance

The difference between the actual direct labor costs incurred and the standard costs for the actual production achieved.
