Question 1

Waterfall Model

Answer 1

Analysis
⬇️
Design
⬇️
Implementation
⬇️
Evaluation
⬇️
Maintenance

Each step is completed one at a time from beginning to end. Each step has specific outputs that lead into the next step

Question 2

Waterfall Model Suitability

Answer 2

• Low user involvement
• Suited to programs with unchanging requirements due to its linear nature

Question 3

Spiral Model

Answer 3

-Same structured steps as waterfall model but introduces the idea of developing the software in iterative stages
-Each successive loop around the spiral produces a prototype and is evaluated which generates a plan for the next iteration until the produce is finished

Question 4

Spiral Model Suitability

Answer 4

-Suitable for high risk projects due to its iterative process
-Good user involvement

Question 5

Agile Model

Answer 5

Different sections of the program are developed in parallel so the developer can be at different stages of development simultaneously

Question 6

Agile Model Suitability

Answer 6

-Adapts quickly to changes in user requirements
-Suitable for any project that requires heavy involvement from the user

Question 7

Extreme Programming Model

Answer 7

An example of agile modelling where its aim is to improve software quality and responsiveness to changing user requirements

Question 8

Extreme Programming Suitability

Answer 8

-High level of user involvement
-Produces high quality code and usability so is suitable for more complex projects
-Suitable for large projects

Question 9

Rapid Application Development ( RAD )

Answer 9

Generates prototypes using an iterative process and then user feedback is used to generate the next , improved prototype

Question 10

RAD Suitability

Answer 10

-Suitable where user requirements are incomplete or unclear at the start
-Suitable for larger projects

Question 11

Black Box Testing

Answer 11

Different sets of inputs are tested to see if they produce the expected output

Question 12

White Box Testing

Answer 12

Checks all part of the code works as intended and every possible route or path of execution is identified and tested

Question 13

Alpha Testing

Answer 13

Testing carried out by a restricted group within the company acting as potential users to report any bugs so they can be fixed

Question 14

Beta Testing

Answer 14

Program is nearly complete and is sent to potential users outside the company to test it in normal operating conditions

Question 15

Acceptance Testing

Answer 15

Show that the finished program works correctly and all requirements are implemented
