SI, From Business to Systems.

Business needs, built into stable systems — so everyday work runs better.

PARTNERS & CLIENTS

What We Do

SI · System Integration

We bring scattered work and data together into one system.
Six steps, from gathering requirements to go-live and operation.

Requirements · Business analysis

We start by looking at how the work actually flows and where it stalls, then write functional, performance and security requirements as things that can be measured.

How the work runs today Interviews with the people doing the work, documenting the flow, the bottlenecks and the exceptions
Requirements you can measure Functional requirements alongside non-functional ones — performance, security, availability
Schedule and risk Managed openly through a work breakdown and milestones

Architecture · UX design

We settle on a structure that scales to the expected traffic and data volume, and check the real screen flow before development starts.

Choosing the structure Monolith or microservices, decided by traffic and data volume
Checking it first Information architecture, wireframes and prototypes confirm the screen flow before any code
Accessibility and responsive layout Web accessibility guidelines (KWCAG) and responsive layout built in from the design stage

Data · System design

Data structures, APIs and the rules for migration, backup and disaster recovery are decided together, so systems stay consistent and can be brought back.

Data standards A standardised ERD and data dictionary, with a plan for migrating existing data
Fixing the interfaces How existing and external systems connect, written down as API specifications
Designing for availability Backup, redundancy and disaster recovery built into the architecture

Development · Integration

Quality is held through code review, automated tests and CI/CD, and progress is shown each cycle as something that actually works.

Quality built in Coding standards, code review and static analysis applied in continuous integration
Automated testing Unit and integration tests catch regressions early
A demo each cycle Direction agreed with the business by looking at something that runs

Quality · Security verification

Performance, security and user acceptance are tested against real scenarios, and the conditions for go-live are fixed.

Proving performance Scenario and load testing confirm response time and concurrency targets
Security review Vulnerabilities checked against the OWASP Top 10, and fixed
Go-live criteria User acceptance testing secures sign-off from the business

중단 위험을 낮춘 시스템 이행과 되돌리기 계획, 운영 모니터링 및 지속 개선 체계

Cutover · Operation · Service levels

A rehearsed cutover and a rollback plan lower the risk of go-live, while monitoring, service level targets and an improvement backlog keep operations in good shape.

Keeping downtime short A rehearsed data migration and a rollback plan keep the risk of downtime low
How it is run Monitoring and alerts, with an incident procedure tied to service level targets
Improving over time Operating data decides what to improve, and it is delivered in priority order
