Question 6

The Analysis stage involves?

Answer 6

• Determining what is required to solve a problem. This involves acquiring and analysing data, and then identifying solution requirements constraints and scope.

Question 7

Solution Requirements can be described as?

Answer 7

Functional and Non-Functional Requirements.

Question 8

What do functional requirements describe?

Answer 8

What the software solution should do.

Question 9

What do functional requirements involve?

Answer 9

1. Input required.
2. Output developed.
3. Functions of the solution including data manipulation and validation.

Question 10

Non-Functional requirements attributes/describes?

Answer 10

Describe the quality attributes of the solution which include:
1. Useability.
2. Reliability.
3. Robustness.
4. Maintainability.
5. Portability.

Question 11

Solution Constraints can be described as?

Answer 11

The conditions or limitations that must be considered when designing a solution.

Question 12

What are the different solution constraints?

Answer 12

1. Economic ( Time and Cost).
2. Technical ( Speed of processing, capacity, availability of equipment, compatibility and security).
3. Social ( Level of expertise of user).
4. Legal ( Ownership and privacy of data requirements).
5. Usability ( Usefulness and ease of use of a solution).

Question 13

Solution scope describes?

Answer 13

The boundaries or parameters of the solution e.g. it identifies what will be and what will not be addressed by the solution.

Question 14

The design stage involves?

Answer 14

Determining how the solution requirements will function and appear. It involves designing the functionality, appearance and user interface of the solution and developing evaluation criteria to determine the efficiency and effectiveness if the software solution.

Question 15

Solution design focuses on?

Answer 15

• The development of design ideas into preferred designs using design principles and a range of relevant design tools.

What are the different design tools?

Answer 17

1. Data dictionaries (both spreadsheet and database).
2. Input-process-output ( IPO) charts.
3. Flow charts.
4. Pseudocode.
5. Object descriptions.

Question 18

Flow-charts are used for?

Answer 18

A step by step approach to solving a problem.

Question 19

Object descriptions are used for?

Answer 19

A collection of views each of which describes one aspect of a project.
