Unit 2 Evaluation of Authored Systems
Evaluation against design specification, completeness, efficiency, platform operation and evidence-based improvements.
How to study for CCEA GCSE Digital Technology
Connect precise digital concepts to scenario evidence, design decisions, testing and evaluation, then rehearse the controlled-practice lifecycle under your centre's current CCEA instructions.
Core concepts
Concept 1
Evaluation compares the finished solution and testing evidence with original requirements and design criteria.
Exam cue: Quote or paraphrase the requirement before judging whether it was met.
Concept 2
Completeness, efficiency and platform suitability are distinct judgements that need evidence.
Exam cue: Use test and user evidence rather than personal preference.
Concept 3
A useful recommendation identifies a limitation, proposed change and expected benefit.
Exam cue: Prioritise improvements that materially affect users, correctness or performance.
Risk pitfalls and guardrails
Describing features without evaluating them.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Claiming the system is complete because it runs once.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Suggesting an improvement unrelated to a documented weakness.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Memory anchors
Evaluation
Evidence-based judgement against stated requirements and criteria.
Complete solution
A solution implementing all required functions and outputs.
Efficient solution
A solution using time and resources proportionately.
Platform suitability
Appropriate operation on the required devices and software.
Refinement
A targeted change made from design, test or user evidence.
Recommendation
A justified proposal for improving the developed system.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
