Development Methodoligies

Question 1

What does ADITDEM stand for and what is its literal meaning?

Answer 1

It stands for ‘A Dance In The Dark Every Monday’ and lists the software development process: Analysis, design, implementation, testing, documentation, evaluation and maintenance.

Question 2

What is iteration, and how does it apply to the ADITDEM model?

Answer 2

Iteration is repeating a previous stage with new information. The ADITDEM model is an iterative process.

Question 3

What is a software specification?

Answer 3

Software specification is produced after discussion between the client and software company. It will clearly outline the features and functions of the program.

Question 4

What kind of contract is the software specification?

Answer 4

It is a legally binding contract between the client and the software company and will be referred to in any disagreements of the final product.

Question 5

How does the systems analyst receive data on the clients needs?

Answer 5

Through interviews, observations and paper trails.

Question 6

What kind of design is used for a program?

Answer 6

Top-down design with stepwise refinement.

Question 7

How does top-down design work?

Answer 7

The whole problem is broken down into smaller sub problems to make them more easy. This allows for the sub programs to be allocated to different members or teams.

Question 8

What are three kinds of design notation?

Answer 8

Pseudocode, structure charts and wireframing.

Question 9

What factors are considered when choosing the program language? (Try to remember three)

Answer 9

-The type of user interface needed
The data types and control structures available
-The type of applications being developed
-The experience of the current programmers

Question 10

What are the four guidelines for writing good code? (Try to remember three)

Answer 10

• The programshould be written in modular style
• Use meaningful variable names
• Use helpful internal comments
• Use of pre-written module libraries
• Use of appropriate white space

Question 11

When should testing take place during the software development process?

Answer 11

Throughout the whole process!

Question 12

What are independent test teams?

Answer 12

Programmers who have had no involvement with the project so far and are used to avoid bias while testing the program.

Question 13

Describe acceptance testing.

Answer 13

Users try out the program in a real life working environment to give feedback of it to the developers.

Question 14

What does a user guide contain?

Answer 14

It contains a description of the softwares features, tutorials on the software.

Question 15

What does the technical guide explain?

Answer 15

Details on how to install the software, info on the min system requirements and how to do trouble shooting.

Question 16

Evaluation

What does the criteria of ‘Correct’ mean?

Answer 16

It meets the software specification.

Question 17

Evaluation

What does the criteria of ‘Readable’ mean?

Answer 17

It is easily understood by another programmer.

Question 18

Evaluation

What does the criteria of ‘Reliable’ mean?

Answer 18

It is free from design and coding errors.

Question 19

Evaluation

What does the criteria of ‘Robust’ mean?

Answer 19

The program does not crash with unexpected input.

Question 20

Evaluation

What does the criteria of ‘Efficient’ mean?

Answer 20

The resources are used in proportion to the scale of the program.

Question 21

Evaluation

What does the criteria of ‘Maintainable’ mean?

Answer 21

Future changes can be done quickly and easily.

Question 22

Evaluation

What does the criteria of ‘Portable’ mean?

Answer 22

It can be easily adapted to run on different platforms.

Question 23

State the three kinds of maintenance carried out by software companies.

Answer 23

• Corrective
• Adaptive
• Perfective

Question 24

What is corrective maintenance?

Answer 24

This is dealing with errors that were not discovered throughout the normal testing process.

Question 25

What is adaptive maintenance?

Answer 25

This is changing the program to be able to cope with new hardware and software, like an updated operating system.

Question 26

What is perfective maintenance?

Answer 26

This is adding extra functions to enhance the program.

Question 27

Between corrective, adaptive and perfective maintenance, which must the client pay for?

Answer 27

The client has to pay for adaptive and perfective. Corrective is mixing errors initially missed, thus adding no new content.

Question 28

Hoe does the Agile Development Methodology work?

Answer 28

Small project teams are formed and assigned to a separate area each. Teams rely on face-to-face discussions to make quick decisions.This makes the process flexible and the project can be easily changed heeding the clients request.

Question 29

What kind of software is Agile Development methodology commonly used to make?

Answer 29

Computer games

Question 30

How does Rapid Application Development work?

Answer 30

The purpose of RAD is to get working code to the market as quickly as possible. It allows you to build a prototype very quickly, give it to the client to retain feedback and make the necessary changes.

Question 31

What kind of software is RAD usually used to make?

Answer 31

Apps for mobile devices.
