Unit 2 Designing Solutions
End-user involvement, target audience, requirements, navigation, storyboards, media sources, timelines, scripts, data dictionaries, wireframes and ERDs.
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
Design documentation translates user and audience needs into a testable multimedia or database structure before development begins.
Exam cue: Choose the design artefact that communicates the required structure or behaviour.
Concept 2
Multimedia documentation describes navigation, screens, media and scripted behaviour, while database documentation defines data, relationships, forms and reports.
Exam cue: Trace each user requirement into a design decision and later test.
Concept 3
End-user feedback should be gathered early enough to refine a prototype rather than only after the solution is complete.
Exam cue: Distinguish an ERD, data dictionary, wireframe, storyboard and navigation diagram by purpose.
Risk pitfalls and guardrails
Treating a visual mock-up as a complete technical design.
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.
Collecting feedback without recording the design change it justifies.
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.
Using multimedia documentation to describe database relationships or vice versa.
Guardrail: Do not combine Units 2-3 with Units 4-5. Filter all revision and assessment claims to the learner's chosen CCEA route.
Memory anchors
User requirement
A capability or constraint the finished system must satisfy.
Target audience
The intended users whose needs shape content and interaction.
Storyboard
A planned sequence of screens, media and interactions.
Wireframe
A structural sketch of a form, report or interface.
Data dictionary
A specification of database fields, types, sizes and rules.
ERD
A diagram showing entities and the relationships between them.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
