SaaS-based integrated planning replaces spreadsheets across thousands of SKUs and cuts inventory by 6.6%
FAIRFAX, Va., Nov. 9, 2026 /PRNewswire/ -- VMS Solutions, a global leader in AI-powered production planning and scheduling software for manufacturing, today announced that Interojo, a South Korean contact lens manufacturer, has deployed the SaaS version of MOZART 3.0 to unify production planning across its operations. Daily planning that once took about two hours now takes around 10 minutes, and inventory is down 6.6%.
Listed on South Korea's KOSDAQ market, Interojo is a vision care company that makes contact lenses under its own Clalen brand and as an OEM/ODM partner for global eyewear companies, exporting to more than 120 countries.
Contact lens production is a textbook high-mix, low-volume environment. Interojo's 200-plus products, from daily to color lenses, branch into variations by prescription, color, function and wear cycle, adding up to thousands of SKUs. Planners previously coordinated them in separate spreadsheets.
With MOZART 3.0, Interojo now plans every step from injection molding to packaging, including outsourced processes, in a single system. The company restructured its bill of materials down to prescription-level SKUs and built its process rules and planners' expertise into the system, so every department now plans to the same standards.
Results
- 92% reduction in daily planning time, from about 2 hours to around 10 minutes
- 99% of master data errors resolved during implementation
- A longer planning horizon that surfaces delivery risks and bottlenecks earlier
- 6.6% inventory reduction through planning that accounts for yield, packaging units and substitute SKUs
"We used to be so focused on building the plan that we missed problems we can now see coming in the data," said a spokesperson for Interojo. "We're also putting MOZART 3.0's AI features to work on our planning data. Our role has shifted from making plans to shaping strategy."
"Interojo shows what integrated planning can deliver in a complex, high-mix environment," said Keyhoon Ko, Chief Global Business Officer at VMS Solutions. "Many manufacturers in the U.S. are managing the same kind of SKU complexity in spreadsheets. The same approach can help them plan faster and carry less inventory."
Interojo runs MOZART 3.0 as subscription-based SaaS. VMS Solutions also offers MOZART 3.0 on-premises or in a dedicated cloud environment, so manufacturers can choose the deployment model that fits their IT and security requirements.
