This
paper introduces a conceptual framework for evaluating different supply chain structures
in the context of modularization and postponement. In the analysis, modularization is
linked to inbound logistics as the combination of different components (or modules) allow
for the assembly of the final product. Postponement, however, corresponds with the
outbound logistics since it is through the distribution function that customers' specific
demand is satisfied. Given this perspective, a taxonomy is introduced and a corresponding
framework for the characterization of four supply chain structures, defined according to
the combined levels of modularization and postponement, is developed: rigid, postponed,
modularized, and flexible.
