a new standard for optimized services

Based on years of experience and know-how, Whynet runs diverse information systems effectively,

driving continuous improvement through integration, linkage, updates, and cost efficiency.

IT Assessment & Consulting

With public-sector and large-scale network build experience,

we assess IT systems and propose optimal improvements.

From legacy analysis to ops guidance, we deliver cost-efficient consulting.

01

AI Adoption Consulting

We apply AI to network and security operations to improve efficiency.

Using proven solutions like Mist AI and MAVIS, we support monitoring.

We also provide automation and tailored AI adoption consulting.

02

Information System Operations & Maintenance

Based on NI/SM operations experience, we integrate management.

With processes based on ISO/IEC 20000, we ensure uninterrupted operations,

preventive checks, rapid response, and continuous system improvement.

03

Infrastructure Operations & Improvement

With public-sector and data center build experience, we connect on-prem and

cloud flexibly. Across IDC migration, build, and operations, we ensure stability

and compatibility, supporting future-oriented optimization.

04

Security Assessment, Operations & Improvement

To block threats in advance, we provide vulnerability assessment and

security monitoring. With ISO/IEC 27001, we run cloud-based security and

privacy protection to build tailored security environments.

05

Dev Environment Build & Operations Support

We build and operate modern DevOps and CI/CD environments.

By optimizing dev environments with network and security, we boost output

and support stable systems aligned with customer needs.

Task Area Details
Phase Activity
Environment Analysis Management Environment Analysis Analyze external factors and management strategy to derive implications for responding to change drivers.
Law/Regulation Analysis Analyze relevant laws and systems to derive requirements that may affect the project and reflect them in target model design.
IT Environment Analysis Review technology trends and changes to analyze applicability and use cases.
Current-State Analysis
(As-Is Analysis)
Business Status Analysis Analyze organizational roles and workflows, then create process maps and activity definitions
to identify issues and improvement needs in the current organization and workflow system.
IT Current-State Analysis • (Business systems) Diagnose current systems to derive issues and improvement needs
• (Data) Diagnose current data to derive issues and improvement needs
• (Infrastructure) Diagnose hardware, software, network, storage, etc. to derive issues and improvement needs
• (IT governance) Diagnose IT work/processes to derive issues and improvement needs
Benchmarking Select benchmarking targets based on issues from current analysis (business & IT), then research and analyze best practices.
Gap Analysis Derive requirements from best practices, then analyze gaps with existing informatization requirements to set improvement direction.
Issue integration and
improvement tasks
• Group related issues derived from current analysis (issues and improvement needs)
• Analyze root causes and derive improvement tasks (apply insights from best-practice research)
Informatization Vision & Strategy Link environment and current-state analysis to set vision, goals, phased execution strategies, and IS build principles
and define technology requirements and information management strategies for IS.
Target Model Design
(To-Be Model)
Detail improvement tasks Detail improvement tasks derived from current analysis (overview, scope, To-Be direction, use cases, etc.).
Business Process Design • Redesign optimized To-Be processes considering improvement tasks, best practices, and IT direction
• Define function requirements for system development by activity unit within To-Be processes
IS Structure Design Establish ideal application structures for strategic IS development.
Data Structure Design Organize data management systems to run the established IS efficiently.
Technology & Security Architecture Design Define required technology elements and infrastructure for strategic IS development.
Integrated Implementation Plan Establish integrated implementation plan Evaluate priorities and strategic characteristics, consider system interdependencies, and build execution structure and schedules.
Total Build Cost Estimation • (SW development) Derive costs from function points (FP); if FP is not applicable, use man-months (MM)
• (Equipment) Specifications, quantities, and amounts for SW/HW purchases
Benefit Analysis • Analyze expected benefits
※ For large-scale IT projects (preliminary feasibility 대상), economic feasibility analysis (B/C, NPV, etc.) is required based on quantitative benefits.
