10 Questions
What is the main advantage of the spiral model for software development projects?
Identifying and analyzing risks at each stage of the project
What are the two most common methodologies in agile development?
Scrum and Kanban
What are the 5 key values of extreme programming (XP)?
Communication, Simplicity, Feedback, Courage, Respect
What is a sprint in agile development?
A boxed period of development with specific goals completed in 1 to 4 weeks
How does extreme programming (XP) promote a positive working environment?
Through practices like 40-hour weeks, dual programming, and coding standards
What is the main concept behind Rapid Application Development (RAD)?
Changing and adapting a project with successive development iterations
What is the purpose of a feasibility study in both Rapid Application Development and the Spiral Model?
To assess the viability and potential success of the project
How does the Spiral Model differ from Rapid Application Development (RAD) in terms of project cycles?
Spiral model cycles expand in progress over time, while RAD focuses on iterative development with each cycle
What are the key stages of each cycle in the Spiral Model?
Determining objectives, identifying and resolving risks, development and testing, planning the next iteration
Why is Rapid Application Development (RAD) considered suitable for projects with lower budgets?
Because the code doesn’t necessarily need to be high quality, and it can be produced in a short time frame
Study Notes
- Rapid Application Development (RAD) involves successive development iterations, beginning with a feasibility study, followed by design, implementation, testing, and evaluation in each iteration, resulting in a prototype that is refined based on user feedback.
- The Spiral Model, similar to RAD, consists of project cycles with stages like determining objectives, identifying and resolving risks, development and testing, and planning for the next iteration, making it suitable for high-risk projects with complex risk analysis.
- Agile methodologies aim to enhance software development flexibility and adaptability to changing user requirements, with common methodologies like Scrum and Kanban, emphasizing user satisfaction over documentation and involving iterative development with prototypes at the end of each cycle.
- Extreme Programming (XP) is an example of a framework within agile methodologies, focusing on values like communication, simplicity, feedback, courage, and respect, with practices such as 40-hour work weeks, pair programming, coding standards, and refactoring to improve code quality without changing functionality.
- While RAD is suitable for low-budget projects with a focus on quick production, the Spiral Model is ideal for large projects with high risks, and agile methodologies like XP emphasize constant communication with end users, potentially leading to increased costs due to the need for user-programmer interaction.
