Study Notes

Overview of Emerging Technologies

  • Emerging technology has different meanings, depending on the context
  • Some define emerging technologies as new technologies in the next 5-10 years that fundamentally change business and societal environments
  • Others understand emerging technologies as innovations of existing technologies, used creatively for modern application
  • Artificial intelligence, first developed in the 1950s, continues to evolve and is still considered emerging technology because of its ongoing development in multiple research areas
  • Emerging technologies can also be defined by specific characteristics

Characteristics

  • Radical novelty: Emerging technologies are radically novel, functioning differently from previous technologies to achieve a similar purpose
  • Relatively fast growth: Growth is observed across various dimensions, including the number of users, funding, knowledge, prototypes, products, and services
  • Coherence: This refers to the convergence of previously disjoint research areas and technologies that have progressed beyond theoretical ideas. This stage reveals an internal logic within the group of technologies.
  • Prominent impact: Emerging technologies influence various sectors, transforming industries and having an amplified economic effect. This transformation can impact various sectors, like businesses, education, healthcare, and individuals globally
  • Uncertainty and ambiguity: Uncertainty surrounds the future applications and outcomes of emerging technologies, and the exact uses are ambiguous. This ambiguity surrounds the possible, unintended, and undesirable outcomes and interpretations of a technology by various social groups.

Emerging Technology Areas

  • Augmented Reality (AR): AR overlays computer-generated information onto the real world view, creating a unified view of both real and computer-generated data
  • Artificial Intelligence (AI): AI simulates human intelligence processes by machines, including learning, reasoning, and self-correction
  • Machine learning: Machine learning in AI enables machines to learn from experience, similar to humans
  • Quantum computers: These advanced computers use quantum mechanics to calculate computations more efficiently than traditional computers
  • The Fourth Industrial Revolution (Industry 4.0 or 4IR) encompasses the stages of industrial revolutions, including mechanical production powered by water and steam, the introduction of electric-powered systems, and the automation era ushered in by the computer industry
  • Other aspects of Industry 4.0 technologies are Big data analytics, the Internet of Things (IoT), Cloud computing, and Augmented Reality (AR)

Requirements Analysis and Modeling

  • Systems development is a systematic process which includes defining, designing, testing, and implementing a new system
  • Systems analysts or requirements engineers are vital in the analysis phase for gathering requirements, analyzing collected data, modeling user needs, and outlining how the required system needs to be built
  • Requirements are statements that describe what the system should do or achieve a certain characteristic
    • functional requirements describe the processes to be performed or data contained
    • non-functional requirements specify a system's operational, performance, security, and cultural/political properties

Requirements Gathering Techniques

  • There are several methods for collecting requirements, including interviews, JAD sessions, and questionnaires
  • Interviews: A structured approach to gather information from clients, users, or other relevant members of the project
  • JAD sessions: A group meeting involving project team members, clients, and users
  • Questionnaires: Predetermined questions used to gather information from a large number of individuals, useful for a broad range of issues

Modeling with Unified Modeling Language (UML)

  • UML is a visual modeling language for software and systems, with various diagrams for different viewpoints
  • Use-case diagrams are functional models that depict how a system interacts with its environment from the user's perspective
