Quick Questions

Shade in the A or B circle for each question.

1. Which list shows the four stages of the program development life cycle in the correct order?

A Analysis, design, coding, testing

B Design, analysis, testing, coding

2. A programmer starts typing code before working out what the program must do. Is this good practice in the life cycle?

A No, the program should be planned in analysis and design first

B Yes, coding first saves time

3. Which stage is mainly about working out exactly what the problem is and what the program must do?

A Coding

B Analysis

4. A student draws a flowchart and writes pseudocode for their program. Which stage is this?

A Testing

B Design

5. Which stage comes immediately after design?

A Coding

B Analysis

Answer Key

The program development life cycle

Section A: Quick Questions

A — Analysis, design, coding, testing

A — No, the program should be planned in analysis and design first

B — Analysis

B — Design

A — Coding

Section B: Match the Pairs

Analysis → Design → Coding → Testing → The four stages of the program development life cycle in the correct order

Analysis → The first stage, where the problem is investigated and the requirements are worked out

Planning is done before coding, so the program is designed first (for example in pseudocode) and then written → Design → Coding

Each stage has its own tasks: the design stage uses tools such as flowcharts and pseudocode → Design: flowchart, pseudocode, hierarchy chart

Coding → Analysis → Testing → Design → The stages are in the wrong order. They must run analysis, design, coding, then testing.

Analysis → Design → Coding → Testing → Debugging → Release → The life cycle in this course has only four stages. Debugging and Release are not extra stages.

Section C: Definitions

program development life cycle — The four ordered stages that take a program from problem to working code: analysis, design, coding and testing. Planning before coding saves time.

Section D: Fill in the Blanks

// Stage 1: analysis
// Stage 2: design
// Stage 3: coding

analysis -> design -> coding -> testing

// Stage 3: coding - write the program

// Stage 4: testing - check it works

CONSTANT Stages ← 4

Section E: Spot the Error

B — Debugging is not one of the four stages. The second stage is Design, so the line should be stage2 ← 'Design'.

B — Writing the program is the task of the Coding stage. In the Design stage you plan the solution, for example by drawing a flowchart.

C — Coding is the third stage and Testing is the fourth. You cannot test a program before it has been written, so this line should be OUTPUT 'Coding'.

A — The program development life cycle has four stages in this course: analysis, design, coding and testing. The constant should be 4.

A — Analysis is always the first stage. You must understand the problem before you can design or code a solution, so the line should be First stage: Analysis.
