What are the pros and cons of RAD?
PROS:
Requirements dont need to be clear at start
Continuous feedback from user
CONS:
Focuses on usability therefore code may not be very efficient
Bad for large projects

What is the Waterfall model?
* A linear sequential approach to software development.
* Each phase must be completed before the next phase can begin.
* Emphasizes planning and documentation.
* Changes made later in the process can be costly.
* Phases typically include requirements gathering, design, implementation, testing, and maintenance.

* Emphasizes collaboration, adaptability, and customer satisfaction.
* Prioritizes delivering working software quickly and frequently.
* Focuses on user feedback and continual improvement.
* Popular Agile methodologies include Scrum, Kanban, and Extreme Programming (XP).

What is extreme programming?
* An Agile methodology that emphasizes continuous testing, frequent releases, and close collaboration.
* Focuses on simplicity, communication, and rapid feedback.
* Includes practices such as pair programming, test-driven development, and continuous integration.
* Promotes the quality of life of developers (ethical)

What is the Spiral model?
* A risk-driven approach to software development.
* Combines elements of the Waterfall model and the prototyping model.
* Emphasizes continual evaluation and risk management.
* Includes multiple iterations of the project.
* Phases typically include planning, risk analysis, prototyping, development, testing, and maintenance.

What is Rapid Application Development?
* An iterative approach to software development.
* Emphasizes speed and flexibility.
* Involves building a functional prototype quickly and refining it through rapid feedback and iteration.
* Emphasizes collaboration between developers and users.
* Often includes tools and frameworks designed to accelerate development.

What is white box testing?
Carried out by developers to check functionality and efficiency of code as it is written

New cards
What is black box testing?
Carried out by the testing team to check all inputs give the expected outputs, regardless of efficiency

New cards
What is beta testing
Carried out a small group of user from outside the company to test for bugs or usability issues

New cards
What is alpha testing
Carried out by people within the company who haven't worked on the project

What is acceptance testing
The final stage of testing where the user checks that the product meets all the requirements in the specification
