NCS Technical Skills: Understanding and Applying Workplace Technology

Technical skills (기술능력) tests whether you understand how technology and equipment work in a professional context — not deep engineering knowledge, but the ability to select appropriate technology, operate equipment safely, and apply technical principles to workplace problem-solving.

Sub-Competencies

Sub-competency	Korean	Focus
Technical understanding	기술이해능력	How technology systems and processes work
Technical selection	기술선택능력	Choosing appropriate tools and methods
Technical application	기술적용능력	Using technology effectively and safely

1. Understanding Technology Systems

Technology Life Cycle (S-Curve)

Technology adoption follows an S-shaped curve:

Introduction: Slow growth, high cost, limited users
Growth: Rapid adoption, costs fall, mainstream use
Maturity: Dominant design, incremental improvements
Decline: Replaced by next-generation technology

Crossing the chasm (Geoffrey Moore): Gap between early adopters and the early majority — many technologies fail here.

Types of Technology Innovation

Type	Description	Example
Radical innovation	Entirely new technology; replaces existing	Smartphone replacing feature phone
Incremental innovation	Improvement of existing technology	Faster processors, better batteries
Disruptive innovation	Initially inferior but eventually displaces incumbents	Digital cameras vs film
Sustaining innovation	Improves performance along existing dimensions	Higher resolution cameras

Disruptive innovation theory (Christensen): Disruptive technologies typically start at the low end of the market, targeting non-consumers or over-served segments, then move upmarket.

2. Intellectual Property and Technology

Types of Industrial Property

Type	Korean	Protection	Duration
Patent	특허	Novel invention	20 years from filing
Utility model	실용신안	Minor improvements	10 years from filing
Trademark	상표	Brand identifiers	10 years, renewable
Design	디자인	Aesthetic appearance	20 years

Key exam point: Patent = 20 years; Utility model = 10 years. Exam frequently tests this distinction.

Trade secret: Protects confidential business information that provides competitive advantage. No registration required, but must be actively kept secret.

3. Safety and Technology (하인리히 법칙)

Heinrich’s Triangle (1:29:300)

For every 1 serious accident, there are:

29 minor accidents
300 near-misses (near accidents)

Implication: Preventing minor accidents and near-misses is the key to preventing serious injuries. Don’t wait for a major accident to act — address near-misses immediately.

Occupational Safety Principles

Hazard types:

Physical: Noise, heat, radiation, falling objects
Chemical: Toxic substances, flammable materials
Biological: Pathogens, allergens
Ergonomic: Repetitive motion, awkward postures
Psychosocial: Stress, harassment, overwork

Hierarchy of controls (most to least effective):

Elimination (remove the hazard)
Substitution (replace with less dangerous)
Engineering controls (barriers, ventilation)
Administrative controls (procedures, training)
PPE (personal protective equipment — last resort)

Equipment Safety Procedures

LOTO (Lockout/Tagout): Procedure to ensure equipment cannot be unexpectedly energized during maintenance.

Lock: Physical device prevents energy activation
Tag: Warning label identifying who locked and why

4. Technical Selection

Technology Selection Criteria

When choosing technology or equipment for a task, evaluate:

Criterion	Questions to ask
Functionality	Does it meet all technical requirements?
Cost	Total cost of ownership (purchase + operation + maintenance)
Compatibility	Does it integrate with existing systems?
Reliability	What is its expected uptime? Failure rate?
Scalability	Can it grow with demand?
Safety	Does it meet regulatory safety standards?
Usability	Can users learn it quickly? Minimal errors?

Total Cost of Ownership (TCO) = Purchase price + Installation + Training + Maintenance + Downtime costs − Salvage value

Tool type	Examples	NCS relevance
Project management	Gantt software, task trackers	Resource and time management
Communication	Video conferencing, messaging	Interpersonal skills
Document management	Cloud storage, version control	Information skills
Data analysis	Spreadsheet tools, BI dashboards	Mathematical skills

Technology Change Management

Introducing new technology fails most often not because of technical issues but because of human resistance.

Kotter’s 8 Steps (summarized for technology adoption):

Create urgency — why change now?
Build a coalition of champions
Develop a clear vision
Communicate broadly
Remove obstacles
Create short-term wins
Build on momentum
Make it stick in the culture
