This Design Project consolidates the learning of Design Project 6A/B but provides the learner with the opportunity to demonstrate the synthesis of a greater resource of knowledge at Level 7. The processes of needs analysis, project scope definition, project research and project reporting are applied to the design of a system that integrates with and supports a larger system, or demonstrates the interaction of systems.

These projects are designed to encourage syndicate group work. The projects also develop the learners' abilities to supplement existing theoretical and technical knowledge with related research and to apply this to the solving of engineering problems.

An example of such a project is:
Produce a comprehensive technical rider for a music festival concert to be held in an outdoor sports stadium. The final report should include:
Complete equipment list and layout diagrams
Technical specifications and layout and structural diagrams of the stages and roof trussing system
Work-flow and signal-flow charts
Wiring lists and wiring diagrams
System specification and calibration instructions
Health and Safety report

Produce a comprehensive music recording studio or on-air radio broadcast studio design, including equipment installation and implementation and acoustic design. The final report should include a complete equipment list and layout diagrams, work-flow and signal-flow charts, wiring lists and wiring diagrams; installation instructions and construction details.
