Definitions:

Ideal Standards

Strictly defined benchmarks in cost accounting that assume perfect efficiency and effectiveness in operation.

Normal Standards

Benchmarks used for budgeting and performance evaluation, representing expected efficiency and costs under normal conditions.

Direct Labor Time Variance

The difference between the expected time to produce a product or service and the actual time taken, often used to measure efficiency.

Actual Staff Hours

Actual staff hours are the real number of hours worked by employees, as recorded for payroll or project management purposes, distinct from scheduled or estimated hours.
