Chapter 2 : Digital Generation GENERATION Z A generation that is surrounded by technology when growing up. More ad-averse (dislike of ads) Spends more hours on mobile devices Thinking about retirement at young age Wants to be personally debt free Characteristics Insightful & Savvy Knows world knowledge (due to the existence of internet) Responsible Self-Starters (hardworking, driven and responsible) Risk-Averse & Adaptable (understand that things can be changed any minute) Tech-Enabled (able to adapt with technology well) Stereotype Negative Traits Have short attention span (cannot focus) Multitasker leading to high stress level Unable to handle f2f interactions High expectation on certain brands and companies they interact with Job-hop and ghost employers (not loyal towards an organisation) Millennials vs Gen Z Similarities Shaped by technology. Mostly lived in a mobile-first world. Differences Shopping habits. POV about branding. POV about money. DIGITAL NATIVE The millennial generation and above, including Generation Z and Generation Alpha HYPERCONNECTIVITY A maximum level of connection between humans and machines through devices and various platforms Chapter 3 : Agile & Digital Thinking AGILE THINKING A way of thinking which enables the ability to respond to change or solve problems quickly and easily Analytical Thinking - examine facts, numbers and problems (analyze) Structural Thinking - coordinate projects, details and task (organize) Relational Thinking - connect with people and emotions (personalize) Experimental Thinking - formulate concepts and plans (strategies) Characteristics Positive attitude Thirst for knowledge Goal of team success Pragmatism (common sense) Willingness to fail DIGITAL THINKING A fundamental paradigm shift from traditional ways of working and learning to be more agile and adaptive with the emerging digital technologies (having digital literacy) DIGITAL LITERACY The ability to use, understand, and engage with digital technologies effectively Chapter 4 : Digital Culture & Society CULTURE A way / set of pattern of a group of people (behavior, belief, values, language etc) DIGITAL CULTURE A concept that describes how technology and the internet are shaping the way that we interact as humans Impact on Digital Culture Payment (e-wallets) Shopping (e-commerce) Service (website) Education (e-learning) Navigation (Waze / Google Maps) News Entertainment (YouTube / Netflix) Social Connection (social media) DIGITAL SOCIETY An interdisciplinary research area and a kind of progressive society that has been formed as a result of adaptation as well as integration of advanced technologies into the society and culture DIGITAL NATIVE A person who has grown up in the digital age DIGITAL DEPENDENCY The overuse of the internet or electronics to the point that one's daily life is affected Chapter 5 : System Thinking & Organizational Innovation SYSTEM THINKING An approach to integration that is based on the belief that the component parts if a system will act differently when isolated from the system's environment or other parts of the system (looks at connected wholes rather than separate parts, e.g. house, food) Summary : A powerful approach to understand the nature of why situations are the way they are AND how to improve results Characteristics of a System 1. Heap vs System Heap Comparison System X If parts are being taken away / added, changes will happen. / (e.g. car system - take away engine, whole car will not work)  2. Whole Greater than Sum? The many interactions among the parts in a system give rise to qualities or properties that you just can't measure merely by adding those parts up E.g. Car parts - can measure the sum of weight of overall car but cannot measure other emergent properties such as comfort and speed 3. Purpose Most systems have a distinct 'point' or purpose in relationship to the larger system in which they are embedded / fixed (indirectly related) 4. Causes & effects are a cycle System thinkers notion of causality - feedback loops (A > B > C > A) 5. Déjà Vu A system archetype (Patterns of behavior of a system expressed by circles of causality have therefore similar structures) Behave in similar ways in very different kinds of settings Benefits of System Thinking Understand and analyze the context within which one operates Bring together different stakeholders Can explore new business opportunities Create compelling vision of the future Understand the complex human factors associated with change Re-design broken systems Chapter 6 : Innovation in Digital Trends BIG DATA Data that contains greater variety, arriving in increasing volumes and with more velocity (very big data that is fast and complex and cannot be processed using traditional methods) CLOUD COMPUTING An environment that provides resources and services accessed via the internet Computer over the Internet Virtualized computing platform Scalable use of computing resources (can be measured) Pay-per-use concept SOFTWARE-DEFINED ANYTHING (SDE) An approach where software is a lever to define and control the working of a hardware (one software control all hardware - e.g. smart home) A growing trend towards disrupting traditional way of thinking E.g. Amazon - World largest bookseller, Netflix - Largest video service by number of subscribers OUTSOURCING vs CROWDSOURCING Outsourcing Comparison Crowdsourcing Focus on what you do best Definition Encourage consumers and users to and let others do the rest take charge and pursue their goals Contract Relationship Partnership Type Internet and beyond Environment Internet Professional organizations or Choice of Public network individuals suppliers Contractors only Number of Unlimited suppliers Regular payment Payment Payment on satisfactory results PROSUMER ECONOMY Consumer demand play a leading role reshaped into the demand chain (provider + consumer) LONG TAIL Refers to the large number of products that sell in small quantities, as contrasted with the small number of best-selling products Head - High demand / best-selling products Long tail - Large numbers of niche products that may not have high sales volume but contribute substantially to the market ECONOMIES OF SCALE Average costs decrease with the increase of production DIGITAL FINANCE Third-party payment companies integrate the gateway interfaces and build a bridge between numerous merchants and banks (e.g. TNG, PayPal, Alipay) COLLABORATION When a group of people come together and contribute their expertise for the benefit of a shared objective, project , or mission (e.g. Google Drive, Microsoft Teams, Skype) Chapter 7 : Innovation through AI ARTIFICIAL INTELLIGENCE The concept of creating computer programs or machines capable of behavior we would regard as intelligent if exhibited by humans Impact of AI on Human Labor 1. Job opportunities ▪ Some jobs may be affected, some jobs may be much needed, new job opportunities 2. Innovations ▪ New things that AI can do EXPERT SYSTEM A system that employs human knowledge captured in a computer to solve problems that ordinarily requires human expertise (a system like ChatGPT, but can solve more expertise / professional / complex problems) Experts > Transfer Expertise > Rules & Inferencing (IF ELSE THEREFORE) > Explanation Capability Importance of Expert System  Preserve knowledge (kept in the system) To train new employees Improve worker productivity MACHINE LEARNING A method of data analysis that automates analytical model building Example : Virtual Personal Assistants Online Customer Support Search Engine Result Refining ARTIFICAL NEURAL NETWORKS (subset of machine learning) (human brain structure) A computer program inspired by certain presumed organizational principles of a real neural network ROBOTICS Involves building machines that are capable of performing physical tasks COMPUTER VISION Focused on equipping computers with the ability to "see", in the sense of interpreting visual images SPEECH RECOGNISATION The process of converting speech signals into digital data (Siri / Google Assistant) NATURAL LANGUAGE PROCESSING (NLP) Deals with the interaction between computers and humans using the natural language Example : Predictive Text (will predict what word you will be writing next / give suggesting words for users to use) Google Search (Learn what we search and gives suggestions / something relevant suggestions) COMPUTER VISION A field of artificial intelligence that enables computers to interpret and make decisions based on visual data from the world, often involving the analysis of images or video Chapter 8 : Innovation through Analytics DATA Is raw, unorganized facts that need to be processed INFORMATION Data that is processed, organized, structured or presented in a given context to make it useful DATA ANALYTICS The science of analyzing raw data to make conclusions about that information and to enhance productivity and business gain (e.g. Google Analytics) [Can be structured or unstructured] Factors of Data Analytics Gather hidden insights (find out / conclude information that we might not know) Generate reports (the overall performance - according to data collected) Perform market analysis (gives understanding to the organization about the market better) Improve business requirements Tools of Data Analytics Clean & Transform Messy Data – Data Preparation OpenRefine (formerly Google Refine) Descriptive Analytics MS Excel Descriptive Analytic, Diagnostic Analytics Tableau Public, QlikView [in-memory data processing] Descriptive Analytic, Diagnostic Analytics, Predictive Analytics, Prescriptive Analytics R Programming – [Descriptive, Diagnostic, Predictive], Prescriptive – can be extended to perform prescriptive analytics to some extent, Free Python - Free RapidMiner – Free, Not Free KNIME – Free, Not Free SAS – Prescriptive Analytic – High, Not Free, Robust  Apache Spark - Prescriptive Analytic – High, Free, Not Free [in-memory data processing], Robust DATA ANALYST A professional who can analyze data by applying various tool and techniques and gathering the required insights BIG DATA Data that is so large, fast or complex that it's difficult or impossible to process using traditional methods Types of big data BIG DATA ANALYTICS A complex process of examining large and varied data sets, to uncover information that can help organizations make informed business decisions Solve advertisers problem and offer marketing insights (understand users interest) Boost customer acquisition and retention (accurately aim customers and retaining them) Helps in risk management A driver of innovations and product development Supply chain management Chapter 9 : Innovation through Internet of Everything (IoE) INTERNET OF THINGS (IoT) The collective network of connected devices and the technology that facilitates communication between devices and the cloud, as well as between the devices themselves (Connect things to the internet and enable communication within the things) Keeps systems functional by sensing and analysing data (automatic with no human intervention - using sensors, chips, actuators, radiofrequency identification (RFID)) NOT to communicate among people NOT to access knowledgeable information CYBER-PHYSICAL SYSTEM (CPS) A system that integrates physical and computational components to monitor and control the physical processes seamlessly (Domain of IoT, needs tight integration and control in closed-loop systems) 3D Printing Augmented reality Advanced robotics It enables responses within the schedule  Decision-making role Benefits of IoT Encourage Machine-to-Machine (M2M) communication Can automate by itself wirelessly without human intervention (collect data fast - efficiency) Can collect more information for better decision making Does not need 24 hour monitoring Reducing cost as optimum utilization of energy and resources are used (all under surveillance) Better quality of life Issues of IoT Compatibility - different devices or protocols within an IoT ecosystem might not be able to work together Complexity - Need professional knowledge to manage and maintain devices and sensors Privacy - as IoT system involves data sharing and Third-Party access, personal information might be leaked out Security - Malicious attacks or unauthorized access towards smart devices (hackable system that can control overall smart devices) Safety - Involves physical harm, damage or hazards caused by the failure or misuse of IoT devices (hackable devices that can turn into smart weapon) INTERNET OF EVERYTHING (IoE) Connection of smart devices, people, data and processes. Everything is linked up, working together to make things smarter and more efficient May lead to privacy concerns as every of our moves are being recorded Chapter 10 : Digital Currency & Blockchain DIGITAL CURRENCY Money in electronic form, existing solely online without physical notes or coins (E.g. Cryptocurrency such as Bitcoin) (take note : not all digital currencies are cryptocurrency) Problems : double-spend Solutions : Blockchain technology E-MONEY A digital version of traditional currency stored electronically, regulated by authorities (E.g. digital e-Wallets) Advantages of Digital Currency Provides users with a more streamlined alternative (organized / efficient / simple) Peer-to-peer transactions Payments are booth instantaneous (on the spot) and low-cost Introduce a higher level of record-keeping and transparency to the sector BLOCKCHAIN A shared immutable ledger that facilitates the process of recording transactions and tracking assets in a business network CENTRALISED LEDGER (Digital currency) The main store of data and is responsible for managing it. There are no reconciliations as there is a central ledger DISTRIBUTED / DE-CENTRALISED LEDGER (Cryptocurrency) Each party has the same copy of data. They work together to store, distribute and validate data Advantages of Cryptocurrency Built-in scarcity may support value (inflation protection) Loosening of government currency monopolies Self-interested, self-policing communities within a blockchain system (miners earn rewards (aka cryptocurrency) by validating  transactions, therefore they will try their best to keep system secure and accurate) Robust privacy protection (miners and public do not know who are the miners) Harder for governments to exact financial retribution (cannot be controlled by government) Fewer barriers and costs to international transactions (makes transactions easy and cheap, minimal (< 1%) or no fees needed - decentralized nature of cryptocurrency) Generally cheaper than traditional electronic transactions (no third-party payment processors, e.g. Visa) Disadvantages of Cryptocurrency Lack of regulation facilitates black market activity (use them in black markets) Potential for tax evasion in some jurisdictions (they are not regulated by national government, therefore attracting tax evaders) Potential for financial loss due to data loss (because it is all "digital") Potential for high price volatility and manipulation (big amount of shares are held by small amount of people, making it easy to control its value, leading to drastic price swings and potential manipulation) Often can't be exchanged for fiat currency (difficult to exchange it to regular money / fiat currency - gold, silver) Limited to no facility for chargebacks or refunds (no one to turn to foe dispute resolutions if being cheated / no refunds) Adverse environmental impacts of cryptocurrency (high energy consumptions) Digital Currency vs Cryptocurrency BLOCKCHAIN Master ledger that records and stores all prior transactions and activity, validating ownership of all units of the currency at any given point in time  Records the entire transaction history to date Transactions are usually irreversible Full nodes that keep complete copies of the blockchain secure and reliable (something like guardians of the blockchain) (take note: it is different with miners, nodes are the computers) No central authority managing data flow Produce cryptocurrencies as an incentive to maintain the integrity of the network (miners have benefits - avoid corruption) BITCOIN The first immutable and unalterable digital currency / cryptocurrency A medium of exchange, unit of account / standard measure, store of value Little in amount, unduplicable, portable MINERS Serve as record-keepers for cryptocurrency communities, and indirect arbiters of the currencies' value The present and future of Digital Currency Central Bank Digital Currency (CBDC) Features a centralised distributed ledger technology (DLT) Allows central bankers to issue and control the monetary supply Chapter 11 : Digital Security DIGITAL SECURITY RISK An event that could cause loss of or damage to a computer or mobile device hardware, software, data, information or processing capability COMPUTER CRIME Any illegal act involving the use of a computer or related devices CYBERCRIME Online or Internet-based illegal act MALICIOUS SOFTWARE (Malware) Designed to harm or exploit computer systems, often causing damage, stealing information or disruption normal operation 1.
