Four descriptions of stages in the program development life cycle are shown. Draw one line to link each description to its most appropriate program development life cycle stage. Not all program development life cycle stages will be used.

(a)Four descriptions of stages in the program development life cycle are shown. Draw one line to link each description to its most appropriate program development life cycle stage. Not all program development life cycle stages will be used. Program development life cycle description develop an algorithm to solve the problem by using structure diagrams, flowcharts or pseudocode detect and fix the errors in the program identify the problem and its requirements write and implement the instructions to solve the problem Program development life cycle stage analysis coding design evaluation testing[4]
(b)Identify three of the component parts after a problem has been decomposed.[3]

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

Mark scheme

Marking points from the official mark scheme (May/June 2023). The mark or mark type is shown in brackets.

[1] (a) develop an algorithm to solve the problem by using structure diagrams, flowcharts or pseudocode -> design
[1] (a) detect and fix the errors in the program -> testing
[1] (a) identify the problem and its requirements -> analysis
[1] (a) write and implement the instructions to solve the problem -> coding
[1] (b) inputs // what is put into the system
[1] (b) processes // actions taken to achieve a result
[1] (b) outputs // what is taken out of the system
[1] (b) storage // what needs to be kept for future use
