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
