Complete Questions & Answers (100%
Correct)
Systems development methodology - ANSWER - A standard process followed in an organization to conduct all the steps necessary to analyze, design, implement, and maintain information systems.
systems development life cycle (S D L C) - ANSWER - The traditional methodology used to develop, maintain, and replace information systems
- Features several phases that mark the progress of the systems analysis and design efforts
Describe the information systems development life cycle - ANSWER - - A circular process, with the end of the useful life leading to the start of another
- At any given phase the project can return to a previous phase when needed
- Can be an iterative process
5 stages of the Systems Development Life Cycle - ANSWER - 1. Planning
2. Analysis
3. Design
4. Implementation
5. Maintenance
(Repeat)
Evolutionary Model - ANSWER - A spiral process in which one is constantly cycling through phases at different levels
Planning Stage - ANSWER - - Need for a new or enhanced system is identified
- Needs are identified, analyzed, prioritized, and arranged
- Determine the scope of the proposed system
- Baseline project plan is developed
Analysis Stage - ANSWER - - System requirements are studied from user input and structured
- Requires careful study of current systems, manual and computerized, that might be replaced or be enhanced
- Output is description of the alternate solution recommend by the analysis team
Design - ANSWER - Analyst converts the alternate solution into logical and physical specifications Logical Design - ANSWER - The design process part that is independent of any specific
hardware or software platform
Physical Design - ANSWER - The logical specifications of the system from logical design are transformed into technology-specific details from which all programming/system construction can be accomplished
Implementation - ANSWER - - Occurs when the information system is coded, tested, installed, and supported in the organization
- New systems become part of the daily activities of the organization
Maintenance - ANSWER - - The phase in which an information system is systematically repaired and improved
- Organization's needs may change over time requiring changes to the system based on
user's needs
1. Analysis
2. Design
3. Implementation - ANSWER - What is the heart of the Systems Development?
Planning --> Analysis --> Logical Design --> Implementation -->Maintenance - ANSWER
- What is the traditional waterfall SDLC?
Agile Methodologies - ANSWER - This methodology has 3 key principles:
1. A focus on adaptive rather than predictive methodologies
2. A focus on people rather than roles
3. A focus on self-adaptive processes
eXtreme Programming - ANSWER - its use of two-person programming teams, described later, and having a customer on-site during the development process. The relevant parts of eXtreme Programming that relate to design specifications are (1) how planning, analysis, design, and construction are all fused into a single phase of activity; and (2) its unique way of capturing and presenting system requirements and design specifications.
Scrum - ANSWER - is designed for speed and for multiple functional product releases. The primary unit is the Sprint, which typically runs for two weeks to a month.
Object-oriented analysis and design (OOAD) - ANSWER - Systems development methodologies and techniques based on objects rather than data or processes.
Object - ANSWER - A structure that encapsulates (or packages) attributes and methods
that operate on those attributes. An object is an abstraction of a real-world thing in which data and processes are placed together to model the structure and behavior of the real-world object.
