Systematic approach to problem solving

Question 1

Analysis

Answer 1

The definition of a problem and the establishment of the system requirements and data models necessary to solve the problem, after the necessary research.

Question 2

Design

Answer 2

The planning and specification of the data structures, algorithms, modules and interfaces necessary for the solution to the problem.

Question 3

Implementation

Answer 3

Writing the code necessary to create the algorithms and data structures for the design phase, in an iterative process of prototyping.

Question 4

Acceptance testing

Answer 4

A component of testing with the intended users to ensure the intended solution is met.

Question 5

Boundary data

Answer 5

Test input data that lies on the boundary of the system’s expected range.

Question 6

Erroneous data

Answer 6

Test input data that lies outside of the system’s expected range (incorrect data).

Question 7

Normal data

Answer 7

Test input data that lies within the system’s expected range. It should return the expected output.

Question 8

Testing

Answer 8

Running implementations to check for the presence of errors, using selected test data covering normal (typical), boundary and erroneous data.

Question 9

Evaluation

Answer 9

The judgement of the system to check if it has met the required criteria to be an effective solution to the initial problem.
