FINAL DEVELOPMENT
2
HOW TO APPROACH THIS
This section is where you take one concept forward and develop it into an effective and innovative final design solution that meets most of the Design Criteria. The mark scheme for this section falls under' 2.3 Development of final design solution' and '3.3 Quality of design developments'.
​
To quote OCR this section (2.3 & 3.3) should show:
​
'Systematic and progressive iterations result in the most defined and complete design solution
Real time evidence of design thinking throughout, detailing compromises and approaches taken
Final Design solution fully scrutinised by stakeholders
Decisions are clearly highlighted, transparent and demonstrate that all design opportunities in the context or focus area have been covered.'
'Design Developments presented in a way that fully explains the candidates thinking, so that stakeholders and users fully understand the design decisions taken
Highly effective and detailed communication of the progression from one stage of a design, concept or part of a design/component to the next, and the journey taken, as appropriate, to gain feedback
Sophisticated models and early prototypes on a component and assembly level, complex CAD drawings, visualisations, simulations and virtual testing.'

So where to start...
Think about the idea you are taking forward...
​
-
What do you not know/understand about this idea?
-
What do you need to check? test? refine?
-
What tools/equipment could you use to test / prototype different aspects?
-
How might these differ to previous prototyping?
Then the first step is the make a plan to tackle this...
How can we plan?
Look at the example below. This shows a students idea at the end of the initial development stage and a final concept. What happened in between was the 'Final Development'.
How and what did the student do in order to get to the final idea?
What aspects did they have to 'develop'?
What did they need to understand about the design in more detail?
Now over to plan your own development...
Using a similar technique directly onto your slides plan your development. Break your idea down into parts focusing on key features of your idea which could be:
​
Functionality | Usability | Aesthetics | Mechanics | Materials | Ergonomics | Electronics | Safety
​
​
This will then allow you to have focus over the next few sessions. Every lesson you should pick one of the aspects you need to develop and use a technique (s) that would be most appropriate to help you develop that aspect of the design.
​
Further Research
Throughout this section you will find that you will NEED to do FURTHER RESEARCH as it helps you develop your design effectively and efficiently. Looking at other products to help you is one of the best ways to get ideas, inspiration and a solution to that 'problem' you face.
For example: the at home bike security device need the back section to love forward and back along a track system. If you were going to try and design that from scratch it would take you ages. Instead you can look to other products to help to speed up that design process. Designs / systems that have already been tried and tested.
Drawer Runners:
These slide smoothly back and forwath repeatedly so may be useful to analyse
Camera Slider track:
These slide smoothly to create stability for filiming so again may be useful to analyse further
Brio:
Is it enough to have wheel sliding along a groove in a track?
You could then use the above techniques as inspiration and prototype that part of your design using some of the techniques above to see which would work best.
​
Below is an example where extra research has been carried out in the development stage to establish the correct size and proportions of the overall product but also particular critical aspects of the design.
User Review & Design Criteria
Throughout this section you will need to consistently check in with your primary user OR a stakeholder if they are easier to access. For each development you should get their thoughts or opinion. MAKE SURE THIS IS EVIDENCED!
​
You should also be consistently referring to your Design Criteria - these are put together to ensure that you stay focused to the brief and you are constantly thinking about what you are trying to achieve in order to make a successful product.
​
The example below shows how the student uses thoughts and feedback from the user to guide the development of the design and also highlights in pink where the change in design has also met the Design Criteria showing how this was considered throughout.
