1. What is system development? System development is a set of activities used to build an information system.

Describe the five phases of the system development life cycle (SDLC). -planning
-analysis
-design
-implementation
-operational,support, and security

2. What are four types of feasibility, and what does each measure?

-Operational feasibility measures how well the proposed information system will work.

-Schedule feasibility measures whether the established deadlines for the project are reasonable.

-Technical feasibility measures whether the organization has or can obtain the hardware,
software, and people needed to deliver and then support the proposed information system.

-Economic feasibility, also called cost/benefit feasibility, measures whether the lifetime
benefits of the proposed information system will be greater than its lifetime costs.

What are six techniques used to gather data and information? -Review Documentation
-Observe
-Survey
-Interview
-JAD Sessions
-Research

3. How is UML used? The UML is a graphical tool that enables analysts to document a system.

How is a use case diagram different from a class diagram? A use case diagram graphically shows how actors interact with the information system.
A class diagram graphically shows classes and subclasses in a system.

4. What are the three major activities of the operation, support, and security phase?
(1) perform maintenance activities,
(2) monitor system performance, and
(3) assess system security.

Describe each type of maintenance activity.
Corrective maintenance, which is the process of diagnosing and correcting errors in an information system.
Adaptive maintenance is the process of including new features or capabilities in an information system.
perfective maintenance is a process to make the infor mation system more efficient and reliable.

5. What is a computer security plan?
A computer security plan summarizes in writing all of the
safeguards that are in place to protect an organization’s
information assets.

What three things should a computer security plan do?
1. Identify all information assets of an organization, including hardware, software,
documentation, procedures, people, data, facilities, and supplies.

2. Identify all security risks that may cause an information asset loss. Rank risks from
most likely to least likely to occur. Place an estimated value on each risk, including lost
business. For example, what is the estimated loss if customers cannot access computers
for one hour, one day, or one week?

3. For each risk, identify the safeguards that exist to detect, prevent, and recover from a loss.
