Problem Solving Methodology

Question 1

What is the Solution Requirements?

Answer 1

Broad description of what is needed – Full SRS required in software
development

Question 2

What are Constraints?

Answer 2

Limitations on the solution. These can include Economic, Technical, Social, Legal and Non Technical

Question 3

What is the Scope?

Answer 3

A List what the solution will/will not do. Also known as defining the boundaries

Question 4

What is the purpose of a Software Requirements Specifications (SRS)?

Answer 4

The purpose of an SRS is to break down problems into their component parts. These include UML’s, Functional and Non-Functional Requirements and Data Collection

Question 5

What is the purpose of a Unified Modelling Language (UML)?

Answer 5

The purpose of an UML is to represent interactions between solutions, users and networks. This can be shown with a Data Flow Diagram, a Use Case Diagram and a Context Diagram

Question 6

What is the difference between Functional and Non-Functional Requirements?

Answer 6

Functional Requirements refer to what the system must be able to do (verb) whereas a Non-Functional Requirement refers to what the system must be (adjective)

Question 7

What are various Data Collection Techniques?

Answer 7

Survey, Observation and Interview

Question 8

What are some examples of Design Principles that relate to Functionality?

Answer 8

Flexibility, Robustness, Ease of Use, Error Tolerance and Navigation

Question 9

What are some examples of Design Principles that relate to Appearance?

Answer 9

Contrast, Alignment, Space, Balance, Repetition

Question 10

Whats the difference between Divergent thinking and Convergent thinking?

Answer 10

Divergent Thinking is creativity and design to produce a range of ideas whereas Convergent is selecting the best plan to fully develop

Question 11

What are examples of Design Tools that represent relationships within a solution?

Answer 11

• Data flow diagram
• Hierarchy chart – importance displayed by placing them up
  higher (eg folder structures)
• Context diagram
• Use case diagram

Question 12

What are examples of Design Tools that represent how data are named, structured or manipulated?

Answer 12

• Data Dictionary
• Object Descriptions Table
• Pseudocode
• IPO Chart

Question 13

What are examples of Design Tools that refer to the Appearance?

Answer 13

• Annotated Diagram/Mockup

- Layout Diagram

Question 14

What is Manipulation with examples?

Answer 14

Turning unprocessed, unorganised and distinct facts and ideas into processed, organised and value-added data. Examples of this include Chart Creating, Average Finding and Calculated Fields

Question 15

When is Evaluation Criteria determined?

Answer 15

Design Stage

Question 16

What are some Electronic Validation techniques?

Answer 16

Existence checks, Range checks, Type Checks, Spell Checks

Question 17

What are some Manual Validation techniques?

Answer 17

Proof Reading, Calculations, Testing Objects

Question 18

When does Informal Testing occur?

Answer 18

Informal Testing happens as the solution is being built

Question 19

When does Formal Testing occur?

Answer 19

Formal Testing occurs after the solution is created with testing tables or other means of testing

Question 20

What is User Acceptance Testing?

Answer 20

User Acceptance Testing is testing done by typical users to iron out any last minute issues, just before the solution is implemented

Question 21

Why do we Test Data?

Answer 21

We test data to make sure every scenario is tested to ensure full functionality

Question 22

What is Penetration Testing?

Answer 22

Penetration Testing is where you get an outside user to try and infiltrate a network

Question 23

What is Internal Documentation?

Answer 23

Internal Documentation is comments in the code for the programmer or future developers

Question 24

What is External Documentation?

Answer 24

External Documentation is instructions on how to use the finished product and is designed for the end user.
