poskom’s success in achieving quality innovation and becoming a “strong small company” was largely driven by the support of its primary contractor, Medison.

Believing that the competitiveness of its partners directly enhances its own, Medison conducts regular audits and on-site visits, providing guidance on all aspects of quality management—from production line layout to packaging.
Although this rigorous quality control initially felt burdensome, it ultimately strengthened poskom’s operational foundation, reducing defect rates to below 0.1% while significantly lowering loss costs and improving productivity.
The partnership between Medison and poskom is built on mutual trust rather than one-sided support. Medison also actively funds R&D efforts of its partners, even covering full development costs for projects that are not ultimately adopted. 

This collaborative model stands as a compelling example of sustainable win-win cooperation between large corporations and SMEs.
