What is variance?
In most production management systems, a "Planned" quantity and material cost is calculated based on the associated Bill of Materials (BOM) and Operatons being performed (Route) creating labor and overhead related costs. The "Actual" quantities, material costs, and labor/overhead costs are issued to a Work in Process (WIP) account and the quantities/values of the produced items are recieved from the WIP account. A variance usually occurs when there is a difference between the issued material cost plus labor and overhead and the recieved material cost of the produced item. The reasons for these variances can be differences in planned vs actual quantities, differences in system or planned cost of materials, labor, or overhead vs actual cost, or any other potential reason for an unplanned difference.

Should every individual employee in an organization plays a role in controlling work activities?
Control is something that every individual employee plays a role in, particularly in organizations where employees have been empowered. But even in organizations where employees haven't been empowered, these employees play a role in measuring, comparing, and correcting performance. However, managers will still be responsible for establishing the standards, approaches, and guidelines for measuring, comparing, and correcting
Causes of direct material quantity variance?
