Question 1:
What is Systems Analysis and Design used for?
Answer: ✔✔ It is used to analyze, design, and implement improvements in the support of users
and the functioning of businesses that can be accomplished through the use of computerized
information systems.
Question 2:
How is Systems Analysis and Design defined?
Answer: ✔✔ A systematic approach to identifying problems, opportunities and objectives;
analyzing human- and computer-generated information flows in organizations; and designing
computerized information systems to solve problems.
Question 3:
What does a Systems Analyst do?
Answer: ✔✔ A Systems Analyst systematically assesses how users interact with technology and
how businesses function by examining the inputting and processing of data and the outputting of
information with the intent of improving organizational processes. The three primary roles of
systems analysis are:
1. An outside consultant to a business
2. Supporting expert within a business
3. Agent of Change in both external and internal situations
Question 4:
What is the Systems Development Life Cycle (SDLC)?
Answer: ✔✔ The Systems Development Life Cycle (SDLC) is a phased approach to analysis
and design that holds that systems are best developed through the use of a specific cycle of
analyst and user activities. The life cycle can be divided into seven sequential phases, although in
reality, the phases are interrelated and are often accomplished simultaneously.
, Question 5:
What are the seven phases of the SDLC?
Answer: ✔✔
1. Identifying problems, opportunities, and objectives
2. Determining human information requirements
3. Analyzing system needs
4. Designing the recommended system
5. Developing and documenting software
6. Testing and maintaining the system
7. Implementing and evaluating the system
Question 6:
What is Human-Computer Interaction (HCI)?
Answer: ✔✔ HCI is the aspect of a computer that enables communications and interactions
between humans and computers. It is the layer of the computer between the two and is a human-
based approach that puts people ahead of organizational structure or culture when creating a new
system.
Question 7:
Why is maintenance performed in system development?
Answer: ✔✔ Maintenance is performed for two reasons:
1. To correct software errors
2. To enhance the software's capabilities in response to changing organizational needs,
generally involving one of the following 3 situations (P.9)
Question 8:
What are Computer-Aided Software Engineering (CASE) Tools?
Answer: ✔✔ CASE tools are productivity tools under the SDLC approach that have been
created explicitly to improve productivity, communicate more effectively with users, and
integrate the work that systems analysts do from the beginning to the end of the life cycle.
Question 9:
What is the Visible Analyst (VA)?
Answer: ✔✔ The Visible Analyst (VA) is an example of a CASE tool that enables systems to do
