35
It includes the analysis of data which determine the requirement specification, description of features for new system, and specifying what information requirements will be provided
Requirements specifications
36
is used in requirement gathering to get as many ideas as possible form group of people
1. Brainstorming
37
reviewing the documentation of an existing system can help when creating AS-IS process document, as well as driving gap analysis for scoping of migration projects
2. Document analysis
38
is a gathering of people who are representative of the user or customers of a product to get feedback
3. Focus group
39
– interfaces for a software product can be human or machine. Integration with external systems and devices is just another interface

67
the design should be so simple so that it can be easily maintainable by other designers
Maintainability
68
Software design principle involved with imparting method to address the complexity of the layout method effectively
OVERVIEW OF DESIGN PRINCIPLES
69
- divide the problems into small pieces and conquer the problems one by one
- Problem partitioning
70
a tool that enables a adesigner to consider a component at an abstrat level without bothering about the internal details of the implementation
- Abstraction
71
forms the basis for function-oriented design approaches
- Funcitonal abstraction
72
details of the data elements are hidden to the users of data. Ot forms the basis for object oriented design approaches
- Data abstraction
73
are the divisions of software that are into separate modules, which has named an addressed and are embedded later on in a completely funtional software
- Modularity
74
is achieved by developing functions that perform only one kind of task and do not excessively interact with other modules
- Functional independence
75
it measure the relative function strength of a module
a. Cohesion
76
it measures the relative interdependence among modules
b. Coupling
77
the fundamental of information hiding suggests that modules can be characterized by the design decisions that protect from the others.
- Information hiding
78
a good system design strategu is to organize the program modules in such a method that are easy to develop and later too, change
- Strategy of design
79
this approach starts with the identification of the main components and then decomposing them into their more detailed sub-components
1. Top-down approach
80
this approach with the lower details and moves upt the hierarchy and is suitable to an existing system
2. Bottom-up approach
81
this principle says that a class shoud have one, and ony one, reason to change.
- Single responsibily principle (SRP)
82
says that classes should be open for extension and closed for modification
- Open/closed principle (OCP
83
name after turing-award winner DR. BARBARA LISKOV of MIT, tells us that all sub-classes must be susbstitutable for their base class
- Liskov substitution principle (LSP)
84
a client should never be forced to implement and interface that is doesn’t use or clients shouldn’t be forced to depend on methods they do not use
- This principle defines that a class should never implement an interface that does not go to use.
- Interface segregation principle (ISP)
85
entities must depend on abstraction not on concretions
- States that the high-level module mist not depend on the low level module, butthey should depend on abstractions
- This principle means that a particular class should not depend directly on another class but on an abstraction of this class
- Dependency inversion principle (DIP)
86
new technologies that are currently developing or will be developed over the next five to ten years, and which will substantially alter the business and social environment
Emerging Technologies
87
Emerging technology may take the form of progressing technology. Novelty or newness can also be generated by putting existing technology to a new use. For example, the applications of artificial intelligence are applied to different uses to achieve different results
Radical novelty
88
Emerging technologies show relatively fast growth rates compared to non-emerging technologies. Growth may be observed across a number of dimensions, such as the number of actors involved, public and private funding, knowledge outputs produced, prototypes, products, and services.
Relatively fast growth
89
refers to the internal characteristics of a group being united and having logical interconnection
Coherence
90
Emerging technology provides benefits for a wide range of sectors, transforms an industry, and exerts much enhanced economic influence. It applies a noticeable impact with narrow scope, as well as wide-ranging impact across domains and potentially the entire socio-economic system by changing the composition of actors, institutions, patterns of interactions among those, and the associated knowledge production processes
Prominent impact
91
are key starting concepts for a wide variety of science and technology studies that focus on the role of the expectations in technological emergence
Uncertainty and ambiguity
92
is the technology that overlays computer-generated display, sound, text, and effects on a user’s view of the real world

The disruptive and cutting-edge technologies, such as the Internet of Things (IoT), robotics, virtual reality (VR), AR, and AI, are changing the way we live and work. Industry 4.0 will lead to changes in traditional production relationships among suppliers, producers, customers, as well as between humans and machines.
* Fourth Industrial Revolution, or Industry 4.0
102
This is the process of collecting, organizing, and analyzing large sets of data from different resources to discover patterns and other useful information. This is used to support real-time decision-making in production and customer management systems. Using cutting-edge technologies, it’s possible to analyze large data and immediately get answers from them.
- Big Data Analytics
103
is a computing concept that describes the idea of everyday physical objects being connected to the Internet and being able to communicate and interact with other devices. This may include sensor and wireless technologies. IoT allows field devices to interact with one another and with more centralized controllers. It will also decentralize analytics and decision-making, thereby enabling real-time responses and results
- Internet of Things (IoT)
104
This is the general term for anything that involves delivering hosted services over the Internet. The performance of cloud technologies will improve, which results in achieving reaction times of several milliseconds.
- Machine data and functionality will increasingly be deployed to the cloud, thus enabling more data-driven services in production systems.
- Cloud Computing
105
AR-based systems support a variety of services, such as selecting parts in a warehouse and sending repair instructions over mobile devices. These systems are currently in their infancy, but in the future, companies will make much broader use of AR to provide workers with real-time information to improve decision-making and work procedures.
