Systems Analysis & Design FINAL EXAM
QUESTIONS AND CORRECT ANSWERS.
Systems Analysis - Answer a problem-solving technique that breaks a system into its components to
study how well they interact to accomplish their purpose; and is a pre-requisite to systems design;
focuses more on the business side of things
Systems Design - Answer is putting those components back together for an improved synergistic effect;
focuses more on the technical and implementation points
Logical Design - Answer translates business user requirements into a system model that depicts
business requirements; does not include possible technical design or implementation of those
requirements
Physical Design - Answer translates business user requirements into a system model that depicts a
technical implementation of the users' business requirements; represents a specific technical solution;
the opposite of logical design
Operational Feasibility - Answer measures how well a solution meets the identified system
requirements to solve the problems and take advantage of the opportunities envisioned for the system;
looks at whether the problem is still worth solving vs. its expected solution cost
Technical Feasibility - Answer determines the practicality, availability and affordability of the proposed
technology and whether we currently posses the necessary technology and technical expertise
Schedule Feasibility - Answer measures whether the project deadlines are reasonable
Economic Feasibility - Answer uses cost-benefit analysis to measure the cost-effectiveness of a
project/solution; determines whether the possible benefits of solving the problem are worthwhile
Functional Requirement - Answer a description on activities and services a system must provide;
consist of the concrete activities and services that make up a system, i.e., the inputs, processes, outputs
and data stores, and that are needed to meet the system improvement objectives
, Non-Functional Requirement - Answer refer to the behavioral attributes of the system, i.e.,
performance factors such as speed of operations and response time, cost of operations, ease of use,
security controls, quality management, documentation, etc.
Data Model - Answer a blueprint for the design of the database
Problem Statement Matrix - Answer a succinct overview of the problems, opportunities and/or
directives that triggered the project
Feasibility Analysis Matrix - Answer compares candidates for the solution to your problem, evaluated
against: technical feasibility, operational feasibility, economic feasibility, and schedule feasibility
Problems, Opportunities, Objectives and Constraints Matrix (POOC) - aka 'Cause and Effect Analysis' -
Answer a technique in which problems are studied to determine their causes and effects; leads to true
understanding of problems and can lead to not-so-obvious, but more creative and valuable, solutions
Use Case Glossary - Answer a simple table naming and defining the use for each process model,
including use case identified, its description, and its participating actors and roles
Use-Case Model - Answer a drawing that represents the relationships between the actors and the use
cases; the use cases are grouped into subsystems and the actors are depicted with stick figures; a line is
drawn between each actor and each use case it has a relationship with (no arrows) (time can be an
actor)
Use-Case Narrative - Answer a very detailed form that tracks information about the process, steps
taken by actors and system response
Entity Definition Matrix - Answer identify the fundamental entities and define them
Context Data Model - Answer includes fundamental business entities and relationships with cardinality;
relationships should be named with verb phrases(ex 'sells', 'responds to', etc.)
