Terms in this set (28)
The activity of creating incomplete test versions of a software program being developed.
rapid application development (RAD)
An alternative to the conventional waterfall model of software development which puts less emphasis on planning tasks and more emphasis on development through the use of prototypes addition to or even sometimes in place of design specifications.
computer-aided software engineering (CASE)
Software tools used to design and implement software that is high-quality, defect-free, and maintainable.
joint application design (JAD)
A process used to collect business requirements while developing new information systems for a company which includes approaches for enhancing user participation, expediting development, and improving the quality of specifications.
agile software development
A group of software development methods in which requirements and solutions evolve through collaboration between self-organizing, cross-functional teams which promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change.
Conducted to determine if creating a new or improved system is a viable solution by determining the costs, benefits, resource requirements, and specific user needs required for completion.
The discipline of carefully planning, organizing, motivating and controlling resources to achieve specific goals and meet specific success criteria.
project management processes
Initiating, planning, executing, monitoring and controlling, and closing.
Translates data and systems from one format to another.
Created throughout the whole implementation process.
A style of computing that divides work into individual, indivisible operations.
Execution of a series of programs on a computer without manual intervention.
real time system
Attempts to guarantee an appropriate response to a stimulus or request quickly enough to affect the conditions that caused the stimulus.
user interface design goal
To make the user's interaction as simple and efficient as possible.
Simulated or actual operational testing by potential users/customers or an independent test team at the developers' site.
Comes after alpha testing and can be considered a form of external user acceptance testing.
computer aided design (CAD)
The use of computer systems to assist in the creation, modification, analysis, or optimization of a design.
A centralized repository of information about data such as meaning, relationships to other data, origin, usage, and format.
data flow diagram
A graphical representation of the "flow" of data through an information system, modeling its process aspects.
A precise yet compact way to model complex rule sets and their corresponding actions which associates conditions with actions to perform.
The SDLC phase that includes testing, training, equipment replacement, and file conversion.
Development of the process and/or information flow of the system.
The SDLC phase where existing business problems and/or opportunities are studied.
A process used in testing systems where the old system and the new system are operated simultaneously to verify the new system is working properly.
systems development life cycle (SDLC)
A process used by systems engineers and systems developers to plan for, design, build, test, deliver and maintain information systems.
A process used to break problems down into smaller problems.
The process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements.
A set of methods where a tester evaluates a user interface.
