When there is a recognized contraint in a business with a multiple product mix, the general rule for production allocation is:

Manufacture the product with the highest Contribution margin per unit of contraint until all demand is satisfied

Manufacture the product with the highest unit Contribution margin until all demand is satisfied

Manufacture the product with the highest total Profit margin until all demand is satisfied

Manufacture the product with the lowest Contribution margin per unit of contraint until demand is satisfied
