Concept: Development Methodologies
Mastery | 100% | Questions | · 1 · 2 · 3 |
Materials on the concept
- End-User Development
- Computer-Aided Software Engineering (CASE)
1.
What can happen when systems are created rapidly, without a formal development methodology?
End users can take over the work of IT specialists.
The organization quickly outgrows the new system.
Hardware, software, and quality standards are less important.
Testing and documentation may be inadequate
2.
What provides software tools to automate development methodologies and reduce the amount of repetitive work in systems development?
CASE
JAD
RAD
CAD
3.
Why can fourth-generation tools not replace conventional development tools?
They are not designed to integrate with legacy systems.
They do not incorporate methods for documentation.
They do not incorporate methods for testing.
They cannot handle large numbers of transactions or extensive procedural logic
Concept: Systems Development Life Cycle (SDLC)
Mastery | 100% | Questions | · 4 · 5 · 6 |
Materials on the concept
- Traditional Systems Development Lifecycle
4.
Which is the first step in the systems development lifecycle (SDLC)?
Systems Analysis
Programming
System Design
Conversion
l approach. Why is that?
All tasks in each stage are done at the same time.
At least one person works on each stage at any given time.
Tasks in one stage must be complete before work for the next stage begins.
Most of the projects using SDLC have failed and fallen off a cliff, much as water does in a waterfall
6.
What work are end users limited to in the systems development lifecycle (SDLC)?
Providing low level system performance requirements and reviewing the technical staff’s work
Providing GUI requirements and GUI mockups
Creating the system’s database back-end
Providing information requirements and reviewing the technical staff’s work
Concept: Prototyping

7.
You are an IT project manager for an advertising firm. The firm wishes to create an online survey tool that will be used to survey focus group reactions to products in development. The most important consideration for the firm is being able to offer the tool as soon as possible as a new corporate service. However, you know that many of the senior managers that are business owners of this project have difficulty in understanding technical or software development issues, and are likely to change their requirements during the course of development. What development method would be most successful for this project?
Prototyping
JAD
End-user development
RAD
8.
As a technical project manager, you have decided to propose implementing a prototyping methodology for a small web-based design project. Identifying the user requirements and developing the prototype are the first two steps you will follow. What are the last two steps you will follow in this project?
First redevelop the prototype and then define the requirements.
Use the prototype and revise and enhance the prototype.
Redefine the requirements several times and then redevelop the prototype.
Require the designers to use and implement the prototype multiple times
9.
What is the preliminary working version of an information system?
JAD
Prototype
Application software package
SDLC

10.
How can management control end-user development?
By requiring Gantt charts
By requiring justification for end-user projects
By establishing standards for project requirements
By developing a formal development methodology

Systems design
12.
What is a business document indicating the direction of systems development, the rationale, the current systems, new developments to consider, the management strategy, the implementation plan, and the budget called?
Project plan
Information systems plan
Mission statement
Request for proposal

Materials on the concept
- 11.1. Problem Solving and Systems Development
- Defining and Understanding the Problem
- Evaluating and Choosing Solutions
16.
Developing an information system has been compared to the problem-solving process. “Define and understand the problem” and “Develop alternative solutions” are the first two steps of systems analysis. What are the remaining two steps?
“Choose the best solution” and “Implement the solution”
“Develop alternative problems” and “Choose the best solution”
“Choose the best solution” and “Identify causes”
“Define alternate problems” and “Evaluate alternate solutions”
17.
According to Laudon and Laudon (2011), when defining a newly discovered problem, what common questions should you ask?
Why is the problem still around? Why wasn’t it solved long ago? Is it really a problem?
What caused the problem? Who should be held responsible for this problem? Why wasn’t it solved long ago?
What caused the problem? Why is it still around? Who should be held responsible for this problem?
