FSC101M — Programme Orientation-I 7 min read

I. Orientation: Technology as an Evolving System

Technology advances in waves, each redefining production, work and the skills a discipline demands. This unit tracks that arc from mechanisation to human-machine collaboration, surveys the technologies driving the current wave, and maps the workforce it produces.

Driver of change: each industrial phase is triggered by a new general-purpose enabler — steam, electricity, electronics, connectivity, human-centric intelligence.
Convergence: modern gains come from technologies combining (AI + IoT + 5G), not acting alone.
Sustainability constraint: since 2015, direction is steered by the UN SDGs — growth measured against social and environmental cost.
Skill shift: automation displaces routine tasks and rewards uniquely human and hybrid skills.

II. Evolution of Technology

A. Industry 1.0 to Industry 5.0

The five phases trace the shift from muscle to machine to intelligent collaboration.

Industry 1.0 (c. 1784): mechanisation via water and steam power; the power loom mechanised weaving.
Industry 2.0 (c. 1870): mass production using electricity and the assembly line; Ford's moving line cut assembly time drastically.
Industry 3.0 (c. 1969): automation through electronics, computers and the PLC (programmable logic controller).
Industry 4.0 (c. 2011): cyber-physical systems where machines communicate via IoT, cloud and AI; the "smart factory."
Industry 5.0 (emerging): human-centric and sustainable — collaborative robots (cobots) work alongside people, restoring craftsmanship and personalisation.
Contrast — 4.0 vs 5.0:
1. 4.0: optimises efficiency and automation, machine-led.
2. 5.0: optimises human value, resilience and sustainability, human-led.

B. Digital Transformation

This is the organisation-wide integration of digital technology that changes how value is delivered.

Scope: not merely digitising documents but re-engineering processes, culture and customer experience.
Enablers: cloud computing, big-data analytics, mobile platforms and APIs.
Example: a bank replacing branch visits with app-based onboarding, using analytics for real-time fraud detection.

C. Sustainable Development Goals (SDGs)

The 17 UN goals, adopted 2015 with a 2030 target, align technology to human and planetary needs.

Relevance to engineering: SDG 7 (affordable clean energy), SDG 9 (industry, innovation, infrastructure), SDG 11 (sustainable cities), SDG 13 (climate action).
Design principle: technology assessed on triple bottom line — people, planet, profit.

III. Emerging Technologies

A. Artificial Intelligence and Machine Learning

Systems that perform tasks requiring human intelligence; ML lets them learn patterns from data rather than explicit rules.

Learning types: supervised (labelled data), unsupervised (clustering), reinforcement (reward-driven).

Core idea: a model minimises a loss function over training data.

TEXT

prediction = model(input)
loss = error(prediction, true_value)
update weights to reduce loss

Applications: medical diagnosis, recommendation engines, generative AI (large language models).
Limitation: bias in data, opacity ("black box"), heavy compute cost.

B. Internet of Things (IoT)

A network of physical objects embedded with sensors that collect and exchange data over the internet.

Stack: sensing layer → network layer → application layer.
Example: a smart thermostat reading room temperature and adjusting heating automatically.
Challenge: device security and data volume.

C. Blockchain

A distributed, tamper-resistant ledger where records are chained cryptographically.

Mechanism: each block stores a hash of the previous block, so altering one invalidates the chain.
Properties: decentralisation, immutability, transparency.
Uses: cryptocurrencies, supply-chain tracking, smart contracts.

D. Metaverse

A persistent, immersive 3D virtual world blending physical and digital experience.

Enablers: virtual reality (VR), augmented reality (AR), digital avatars.
Applications: remote collaboration, virtual training, digital commerce.

E. 5G and Beyond

The fifth-generation mobile standard delivering high speed, low latency and massive device density.

Metrics: up to ~10 Gbps peak, ~1 ms latency, ~1 million devices/km².
Enables: autonomous vehicles, remote surgery, dense IoT.
Beyond (6G): targets terahertz bands and integrated AI-native networks.

F. Edge Computing

Processing data near its source rather than in a distant cloud.

Purpose: cut latency and bandwidth by computing locally.
Contrast — cloud vs edge:
1. Cloud: centralised, high capacity, higher latency.
2. Edge: local, real-time, limited resources.
Example: a camera detecting defects on a production line without round-tripping to a data centre.

G. Digital Twins

A live virtual replica of a physical asset, fed by real-time sensor data.

Function: simulate, monitor and predict behaviour of the physical counterpart.
Example: a jet-engine twin predicting maintenance needs before failure.
Dependency: relies on IoT for data and AI for prediction.

H. Robotics and Industrial Automation

Machines that sense, decide and act to perform physical tasks with minimal human input.

Types: industrial arms, autonomous mobile robots, cobots.
Cobot distinction: safe to share workspace with humans, central to Industry 5.0.
Benefit vs risk: precision and endurance versus job displacement and high setup cost.

I. Intelligent Sensors

Sensors with built-in processing that pre-analyse data before transmitting.

Difference from basic sensors: perform filtering, calibration and decision logic on-chip.
Example: a MEMS accelerometer in a phone detecting orientation and step count.

J. Hardware Security

Protecting computing systems at the physical and chip level.

Threats: side-channel attacks, hardware trojans, counterfeit chips.
Defences: trusted platform modules (TPM), physically unclonable functions (PUFs), secure boot.
Principle: security rooted in hardware is harder to bypass than software-only protection.

K. Medical Informatics

The application of computing and data science to healthcare.

Components: electronic health records (EHR), clinical decision support, telemedicine.
Example: AI analysing radiology scans to flag anomalies for the clinician.
Constraint: patient privacy and data standards (e.g., HL7 interoperability).

L. Clean Energy Technologies

Technologies generating and managing energy with low emissions.

Sources: solar photovoltaics, wind, green hydrogen, battery storage.
Enabling tech: smart grids balancing supply and demand in real time.
Alignment: directly serves SDG 7 and SDG 13.

M. Chip Design and Semiconductor Manufacturing

The design and fabrication of integrated circuits, the substrate of all digital technology.

Flow: design (RTL, layout) → fabrication (photolithography on silicon wafers) → packaging → testing.
Scaling: feature sizes now measured in nanometres (e.g., 3 nm nodes), following Moore's Law.
Significance: national strategic importance; foundries require multi-billion investment.

N. Intelligent Transportation Systems (ITS)

Integration of sensing, communication and control to make transport safer and more efficient.

Components: vehicle-to-everything (V2X) communication, adaptive traffic signals, autonomous driving.
Example: connected vehicles sharing hazard data to reduce collisions.
Dependency: built on 5G, IoT, edge computing and AI together.

IV. Future Workforce

A. World Economic Forum Future of Jobs Report

A periodic WEF study forecasting how technology reshapes employment.

Core finding: automation displaces some roles while creating new ones, producing net churn.
Growth areas: AI and data specialists, sustainability roles, digital and technology roles.
Declining areas: routine clerical, data-entry and repetitive manual roles.
Implication: large-scale reskilling and upskilling within short time horizons.

B. Professional Society Perspectives

Bodies such as IEEE, ACM and engineering councils guide the discipline's evolution.

Roles: setting standards, publishing research, defining codes of ethics.
Ethical emphasis: responsible AI, data privacy, sustainability and public safety.
Value: continuous professional development and credentialing that keeps skills current.

C. Skills Required for Future Careers

Careers now demand a blend of technical depth and adaptable human capability.

Technical (hard) skills: programming, data analysis, AI/ML literacy, cybersecurity, cloud fluency.
Human (soft) skills: critical thinking, creativity, complex problem-solving, communication.
Hybrid skills: combining domain knowledge with digital tools (e.g., a doctor using informatics).
Meta-skill: lifelong learning and adaptability — the ability to reskill as technology shifts.
Contrast — displaced vs demanded:
1. Displaced: predictable, rule-based tasks best done by machines.
2. Demanded: judgement, empathy and cross-disciplinary synthesis machines cannot replicate.
