Study Notes

System Development and Analysis

SDLC stands for Systems Development Life Cycle, which is an approach to develop and maintain computer-based information systems.
Agile methodology emphasizes flexibility and customer collaboration in the software development process.
The primary focus of eXtreme Programming is on customer satisfaction and delivering software quickly.
Object-oriented analysis and design provide a modular and reusable approach to software development, making it easier to maintain and modify.

System Development Phases

The planning phase in SDLC involves identifying an organization’s total information system needs.
The primary focus of the analysis phase in SDLC is on identifying problems and opportunities.
The physical design phase in SDLC involves describing the system’s architecture and components.
The implementation phase in SDLC involves translating the design into a working system.

System Development and Characteristics

System development became more like an engineering discipline in the 1960s.
The major breakthrough in the 1980s was the development of object-oriented analysis and design.
System development shifted to Web application development and wireless PDAs in the 1990s.
A System Development Methodology is a structured approach to developing and maintaining systems.
A system has several characteristics, including components, boundaries, and interactions.

Systems Analyst and Skills

The main responsibility of a Systems Analyst is to identify problems and opportunities and develop solutions.
Systems Analysts require analytical skills, including problem identification, problem analyzing, and problem-solving.
Systems Analysts also require technical skills, which need to be kept up-to-date.
'Systems Thinking' refers to the ability to analyze systems and identify problems and opportunities.
Systems Analysts require interpersonal skills, including communication and collaboration.

System Concepts

Systems Thinking involves breaking down a system into smaller components to analyze and solve problems.
Modularization is the process of dividing a system into modules of a relatively uniform size.
Functionality refers to the extent to which a subsystem performs a single function.
A logical system description portrays the purpose and function of the system without tying it to a specific physical implementation.
Identifying a system provides benefits, including a clear understanding of the system and its components.

Analysis and Problem-Solving

Gap analysis is the process of defining differences between an existing situation and a desired situation.
The problem analysis and solving process involves collecting all relevant information during the analysis phase.
Systems Analysts use analytical skills to identify problems and opportunities and develop solutions.
