CIS 321 DeVry Week 1 Discussion 1 Latest
Who are the typical system stakeholders (the key players), and
what are their unique roles?
CIS 321 DeVry Week 1 Discussion 2 Latest
Seventy percent or more of information system projects have
failed to meet the needs of users and have exceeded budgetary limits. Why do
you think this is? What can the systems analyst do to increase the probability
of having a successful project?
CIS 321 DeVry Week 2 Discussion 1 Latest
Compare and contrast the PM life cycle with the SDLC. Why is
project management different from normal management?
CIS 321 DeVry Week 2 Discussion Latest
What are the challenges in analyzing a system? What are some of
the components in analyzing a system so that it has a high degree of success or
is found unfeasible? Why would a system project fail?
CIS 321 DeVry Week 3 Discussion 1 Latest
Finding the requirements for a new system or a redeveloped
system is a major undertaking and a very high priority. What are some of the
techniques in discovering the requirements (fact finding) for a system? Which
ones work best? Which ones are the most economical? Where in the SDLC do we
most commonly search for requirements?
CIS 321 DeVry Week 3 Discussion 2 Latest
We will focus on the way to build the first diagram in the
process model called a context data flow diagram (CDFD). Give an example of how
process modeling might be beneficial? How does creating the CDFD benefit IT
system development and the user?
CIS 321 DeVry Week 4 Discussion 1 Latest
Discuss the importance and usefulness of data modeling in the
analysis phase. How do we know what data we need to model?
CIS 321 DeVry Week 4 Discussion 2 Latest
What steps can you go through to ensure that you are including
all of the necessary data in your model? How are the techniques of data
modeling applied to problem statements?
CIS 321 DeVry Week 5 Discussion 1 Latest
In this discussion, we will focus on the way to build process
models and discuss their technical aspects. Give an example of how process
modeling might be beneficial, whether specifically for an IT system development
project or not. How are logical process modeling techniques used in detailed
systems requirements analysis?
This week, we will continue to work on how to create good ER
diagrams. More sample problems will be introduced and demonstrated. The
emphasis will be on many-to-many relationships. Why do we need an associative
table for many-to-many relationships?
CIS 321 DeVry Week 6 Discussion 1 Latest
What is a feasibility analysis? Please share an example of
feasibility analysis that is not IT related (or even one that is IT related if
you want to). Show how that experience relates to one or more of the
feasibility tests for operational, technical, schedule, or economic feasibility
described in Chapter 11.
CIS 321 DeVry Week 6 Discussion 2 Latest
What is the difference between systems analysis and systems
design? What are some of the different model-driven methodologies?
CIS 321 DeVry Week 7 Discussion 1 Latest
As a culminating exercise, what key aspects did you learn
regarding the creation, analysis, and management of information systems? How
will this impact your future? What thoughts or issues were developed that
require further exploration?
Explain the purpose of testing. Explain how tests are performed
at different levels in the system, such as stub testing, unit testing,
integration testing, system testing, and parallel and user acceptance tests.
