FINAL EXAM (M1S2) Flashcards
a method that is classically though of as the set of activities that analysts, designers and users carry out to develop and implement an information system.
System Development Life Cycle
the basis for a candidate system is the recognition of a need to improve information system or a procedure.
Project Selection
Environment-based ideas originate from?
Customers, Vendors, Government sources and the likes.
Stages of system Development Cycle:
- Planning
- Analysis
- Design
- Implementation
- Testing and Deployment/Integration and Maintenance/Support
Obtain approval for the project, initiate, assess feasibility, plan and schedule.
Planning Stage
Define the problem and scope of the existing system.
Planning Stage
Overview of the new system and determine its objectives
Planning Stage
Confirm Project feasibility and produce project schedule.
Planning Stage
During this phase, threats, constraints, integration and security of the system is considered.
Planning Stage
a feasibility report for the entire project is created at the end of this phase
Planning Stage
Understanding business needs and processing needs
Analysis Stage
Gather, analyze and validate the information
Analysis stage
define the requirements and the prototype for the new system.
Analysis stage
Evaluate the alternatives and prioritize the requirements.
Analysis stage
Examine the information needs of end-users and enhance the system goal.
Analysis stage
SRS is prepared at the end of this stage.
Analysis stage
it specifies the software, hardware, functional and network requirements.
(SRS) Software Requirement Specification Document.
Define solution system based on requirements and analysis decision
Design Stage
includes the design of applications, networks, databases, user interfaces, and system interfaces.
Design Stage
Transform the SRS document into a logical structure, which contains a detailed and complete set of specifications that can be implemented in a programming language.
Design Stage
create contingency, training, maintenance and operation plan.
Design Stage
review proposed design. ensure that the final design must meet the requirements stated in the SRS document.
Design Stage
prepare a design document
Design Stage
construct and implement the design into source code through coding.
implementation stage
combine all the modules into a training environment that detects errors and defects
Testing and Deployment/Integration stage
integrate the information system into its environment and install the new system
Testing and Deployment/Integration stage
a “__________________” that contains an error is prepared through a test plan the includes test-related tasks such as test case generation, testing criteria, and resource allocation for testing.
Test Report
Keep system healthy and improve
Maintenance/Support
includes all the activities such as phone support or physical on site support for users that are required once the system is installed.
Maintenance/Support
implement the changes that software might undergo over a period of time or implement any new requirements after the software is deployed at the customer location.
Maintenance/Support
it also includes handling residual errors and resolving any issues that may exist in the system even after the testing phase.
Maintenance/Support
may be needed for longer time for large systems and for a short time for smaller systems
Maintenance/Support
A system project may be dropped at any time prior to implementation although it becomes more difficult (and costly) when it goes past the design phase.
Project Termination
