Manufacturing and service organizations must choose the mix of products that they will
produce and sell. Decisions about product mix can have a significant impact on an organization’s
profitability. Each mix represents an alternative that carries with it an associated
profit level. A manager should choose the alternative that maximizes total
profits. The usual approach is to assume that only unit-based variable costs are relevant
to the product mix decision. Thus, assuming that non-unit-level costs are the same for
different mixes of products, a manager needs to choose the mix alternative that maximizes
total contribution margin
