app
A software application that runs on a mobile device, such as a smartphone or tablet.
rapid application development (RAD)
A team-based technique that speeds up information systems development and produces a functioning information system. RAD is similar in concept to joint application development (JAD), but goes further by including all phases of the System Development Life Cycle (SDLC).
structured analysis
A traditional systems development technique that uses phases to plan, analyze, design, implement, and support an information system. Processes and data are treated as separate components.
systems support and security phase
During the systems support and security phase of the SDLC, the IT staff maintains, enhances, and protects the system.

users
Stakeholder inside or outside the company who will interact with the system.
The SDLC model
Systems Planning, Systems Analysis, Systems Design, Systems Implementation, Security Systems and Support
agile methods
Systems development method that attempts to develop a system incrementally, by building a series of prototypes and constantly adjusting them to user requirements. Related to adaptive method.
object-oriented (O-O) analysis
The act of understanding an information system by identifying things called objects. An object represents a real person, place, event, or transaction. Object-oriented analysis is a popular approach that sees a system from the viewpoint of the objects themselves as they function and interact with the system.
systems planning phase
The first phase of the SDLC. During this phase the systems project gets started. The project proposal is evaluated to determine its feasibility. The project management plan is formulated, with the help of CASE tools where appropriate.
systems implementation phase
The fourth phase of SDLC. During this phase the new system is constructed, programs are written, tested, and documented, and the system is installed.
Project management
The process of planning, scheduling, monitoring, controlling, and reporting upon the development of an information system.
systems analysis phase
The second SDLC phase. The purpose of this phase is to build a logical model of the new system.
systems design phase
The third SDLC phase. The purpose of systems design is to create a blueprint for the new system that will satisfy all documented requirements, whether the system is being developed in-house or purchased as a package
