What Are Materials Variances? And What Are Carryovers?

Author: Vince Levenda

'Materials Variances' is the difference between the planned quantity of materials required to produce a quantity of output and the actual quantity of materials used to produce that quantity of output. Or the planned quantity of production output from given materials less the actual quantity of production output from those materials.��

Higher Cost Of Goods Sold and Days Inventory Outstanding numbers are indicative of materials variances.�

Materials variances are associated with supply issues and so necessitate an increase in safety stock to combat stockouts.�

If the additional materials required to complete the production run are unavailable an additional production run will be required when the materials come in which will incur machine set-up cost. That would mean an increase in quantity of inputs without a corresponding increase in quantity of output.�

To manage materials variances it is necessary to link�process control and Quality Assurance data to your production scheduling software. Ensure production scheduling software is integrated with enterprise software such as SAP. Aggregate data originating from PLCs on MS SQL server. The root cause of higher COGS and higher DIO now becomes clear.�

Here is a brief, instructional excerpt (accurate at the time of publication of this article) from the Oracle website for�comparison.

"You can use Production Scheduling to schedule production orders or process batches maintenance visits and work orders, or you can decide to simultaneously plan both production and planned orders from Advanced Supply Chain Planning." � Plan both production and planned orders? � "Integrated with Oracle Advanced Supply Chain Planning: schedule both actual production and planned orders." � Man,�schedule both actual production and planned orders! � Oracle really need to get a clue. Scheduling means before the event - the "planned orders" part. You won't know what was actually produced - the "actual production" - until after the event. � Did they mean to say schedule both carryovers and planned orders? Carryovers are the difference between the quantity of production output previously scheduled and the quantity of actual production output. The quantity that was planned to be produced less the quantity actually produced. Carryovers are analogous to variances except that carryovers relate to output over a given period of time whereas variances relate to output from given materials. � Theology: � "Friendship is their profession, truthfulness is their pasture, and sincerity is their meadow. In their favorite company they do not wound each other, for they know that injuring each other is injuring themselves. They are in union at the time of separation, and separation is banished among them. From truthfulness and sincerity, they do not merely tolerate each other, nor do they flee each other when they hold conversation. All are servants of each other, and all are teachers of each other." Ruzbihan Baqli � Excerpt from Teachings of Sufism by Professor Carl W. Ernst, University of North Carolina.�� Methodology:

Carry any jobs not run as scheduled to next shift and ensure all incomplete jobs are on the schedule.

Thats carry as in balance carried forward. Which does not actually involve dragging and dropping with the mouse.
