A labor-intensive industry that no longer depends on people:
data leads the process and the production floor self-learns.
Factories worldwide connect in one language,
setting a stable standard for the 3-party supply chain.We make labor-intensive industry one where data leads the process and the production floor self-learns, and set the 3-party supply chain standard.

AI Algorithm and Software R&D for Interpreting Human-Dependent Production

Core assets: process interpretation algorithms, a domain term dictionary, and standard data from 4 years at multiple Vietnam factories.
These three turn production-floor tacit knowledge into a reusable knowledge asset.

2-B. Product Flow

Four Stages from Customer Need to Product

At the customer site, IO organizes the requirements, contract scope and draft screens (Wireframe), and Manager defines them as product features.
Director completes the screens and usage flow of each feature as the development baseline (Implementation Story).
AI Experience builds the screens and AI features from this baseline, and Architecture designs the data and server structure.Manager defines the customer requirements IO has organized as product features, Director completes the development baseline (Implementation Story), and AI Experience and Architecture build it.
Problems found in development and real use are fixed starting from that stage's baseline, so document and product never diverge.
Roles talk to each other freely, and the baseline is kept as one document.

2-C. IO Team

IT Team of Domain Experts from Sewing Floors

IO (Integration & Optimization) is a team of domain experts from apparel vendors and sewing factory floors.
It connects the information scattered across a customer site (Integration) and turns work hardened by manual entry and duplicate reporting into a system flow (Optimization).
Unlike general ERP vendors, where development and domain teams are separate, people who know operation breakdown, cost design and on-floor measurement interpret customer requirements directly and hand them over as development baselines.IO (Integration & Optimization) is a team of domain experts from apparel vendors and sewing factory floors. Staff who know operation breakdown, cost design and floor measurement read customer requirements directly and pass them on as development baselines.
How We Deploy
CUSTOMER
Diagnosis

Owns customer contact from first meeting to post-rollout adoption, diagnosing problems by process and cost, not by feature pitch.

PROCESS
Process Mapping

Maps order, production and shipment flows of vendors and factories in Vietnam and Indonesia as system-view workflow charts.

SYSTEM
System Consulting

Reviews current ERP, MES and Excel use, separates what to keep from what to replace, then decides which data moves to Monolis and designs the migration.

SPEC
Spec Translation

Turns vague business requests into feature-level requirements the development team can build, and explains technical limits back in business terms.
