Definition

Planning the solution before coding using modelling tools: algorithms (pseudocode, flowcharts), structure charts, DFDs, class diagrams, storyboards, decision trees and data dictionaries.

Example: Link each design tool to its purpose: DFD = data movement; structure chart = module hierarchy; class diagram = classes and relationships.

Found in: syllabus, course specifications, 2025 HSC marking guidelines, sample exam and familiarisation guidelines, school notes, past SDD papers.

Where you'll use it in the test

Syllabus area: Y11 Programming Fundamentals.

Question types it can appear in

Drawing: Draw a DFD, structure chart, flowchart, storyboard or class diagram

How to use it

A model sentence

General advice, built from the definition and example above

“Planning the solution before coding using modelling tools: algorithms (pseudocode, flowcharts), structure charts, DFDs, class diagrams, storyboards, decision trees and data dictionaries.” Then apply it: Link each design tool to its purpose: DFD = data movement; structure chart = module hierarchy; class diagram = classes and relationships.

In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.
