Cards in this deck (10)
- 1Programming methodologies: Waterfall LifecycleSeries of stages, completed in sequence.
Analysis stage uses feasibility study.
If changes need to be made, all levels must be revisited. - 2Advantages vs disadvantages: Waterfall Lifecycle-Straightforward/ simple to manage.
-Clear documentation
-Lack of flexibility
-Limited user involvement - 3Programming methodologies: Agile methodologiesMay not be completed in linear sequence.
Iterative process, constant user feedback.
Prototype built at each stage. - 4Advantages vs Disadvantages of Agile methods:-Flexible to change
-Regular user input
-Poor documentation
-Requires constant interaction w/ user. - 5Programming methodologies: Extreme programmingModel built on user requirements.
Aim is high-quality code.
Use pairs of programmers, one writes while one critiques.
Produces 'working versions' - 6Advantages vs Disadvantages of extreme programming-Produces high quality code
-Constant user involvement
-Higher cost as more ppl needed
-Depends on teamwork - 7Programming methodologies: Spiral modelUses same stages but in a repetitive loop. Each loop creates a prototype.
-Analysis, design, implementation, evaluate
Used for large-scale/ high-risk projects. - 8Advantages vs Disadvantages of spiral model-Thorough risk analysis/ mitigation
-Caters to changing user needs
-Expensive to hire needed risk assessors
-High cost due to prototypes - 9Programming methodologies: Rapid application development (RAD)User needs gathered w/ focus groups, given incomplete version of solution to trial
Depends on partially-functioning prototypes that are built upon.
Used when user needs unclear/incomplete. - 10Advantages vs Disadvantages of rapid application development (RAD)-Caters to changing user needs.
-Reduced development time as focus on main features.
-Poor documentation
-Fast pace so may reduce code quality
