How to use it in an answer
A model sentence
“How simply code can be corrected or updated later; helped by comments, meaningful names, modular subroutines and version control.” Then apply it: Use it to justify modular code in an evaluate or justify answer.
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.
Command words used with it
- Explain: Relate cause and effect; make the relationship between things evident; provide why and/or how. (2023 Software Design and Development HSC Q26 (9 marks): Code reading, maintainability and testing)
Technique for the question types
- Multiple choice: Read all four options, rule out wrong ones, pick one; no penalty for guessing so never leave blank.
- Short answer: One clear point per mark, use the stimulus and course terms, and answer the command word.
- Extended response: Plan with the command word, give a judgement or explanation supported by named details from the stimulus, use course terms and cover both sides when asked.
What the marking guidelines and feedback say
Old-syllabus question. Use for practice on the overlapping skill only. The new Software Engineering exam does not use the old SDD terms (e.g. CASE tools, system flowcharts, EBNF, assembly).
Common mistakes
- Use the term exactly as the syllabus words it, then link it to the scenario in the question; the 2025 feedback repeatedly rewards using the stimulus.
- Answer the command word: outline gives main points only, explain gives a reason or cause, discuss gives both sides.
