Answer 14

Bigbang Model

Question 15

The block diagram of bigbang model:

Answer 15

1. time
2. software product
3. effort
4. resources

Question 16

Big Bang model is best suited in the following cases:

Answer 16

1. small projects
2. small development teams
3. project with no specific requirements
4. experimental projects
5. project for learning purposes

Question 17

• collecting and documenting the needs and expectations of stakeholders for the software system.
• Clear and well-understood requirements are essential for successful project outcomes.

Answer 17

Requirements Gathering BigBang

Question 18

involves building all components of the software system simultaneously. Unlike incremental development, there is no gradual progression through stages or modules.

Answer 18

Development bigbang model

Question 19

entails checking the entire system as a whole for bugs, errors, and inconsistencies. This approach carries a higher risk due to the lack of incremental testing.

Answer 19

testing bigbang

Question 20

releasing the entire system to users or customers at once. Simultaneous deployment can pose challenges, especially if issues are discovered after deployment.

Answer 20

deployment bigbang
