Software Devlopment - Computer Science

Question 1

Name four approches to Devlopment methodologies

Answer 1

• Waterfall cycle
• Agile methodologies
• Extreme programming
• The spiral model

Question 2

List some characteristics about the Waterfall model.

Answer 2

• Software is devloped in a linear fashion
• Each stage is checked before moving onto the next stage.
• Suitable for small projects with no uncetain requirements.

Question 3

List characteristics about the Rapid Application Devlopment.

Answer 3

• Heavily emphasies rapid prototyping and iterative delivery.
• a prototype is built and the user is consulted.
• Modifications area added as the solution is developed.
• Process only continues if the client is happy with the prototype.

Question 4

List characteristics of ths spiral model.

Answer 4

• Uses structured steps as the Waterfall model but introduces the idea of developing software as an iterative process.
• Each time the cycle is competed the customer supplies the feedback and risk analysis looks at the possibility of overuns of time / money requirements.

Question 5

List characteristics of agile methodologies.

Answer 5

• Group of methodologies which focus on diea that requiremenths way change during the development process.
• Software is developed in incremental parts.
• Requirements specifications are continually refined to the customers needs.

Question 6

List characteristics of extreme progamming .

Answer 6

• A type of agile software devlopement process.
• Iterations are very short
• Emphasis on pair programming: code review and unit testing.
