Develop
Designing the logic and structure of an algorithm before coding
- Use pseudocode to outline logic in plain, language-independent steps
- Use flowcharts to visualise control flow using standard symbols
- Identify inputs, outputs, and processing requirements
- Apply control structures: sequence, selection, iteration
Construct
Translating the designed algorithm into working code
- Implement using appropriate data structures and control structures
- Follow language conventions and style guides
- Use modular design - break complex problems into functions or classes
- Test logic incrementally during construction
Document
Documenting involves commenting code, providing algorithm descriptions, explaining rationale
- Inline comments: explain non-obvious logic within the code
- Algorithm descriptions: high-level explanation of what the algorithm does and why
- Explain rationale: document design decisions, trade-offs, and assumptions
- Keep documentation updated as the algorithm evolves
