Step 4. Justify your recommendation and explain how it works

If you’ve followed all the previous steps well you should be able to demonstrate that you’re proposing an appropriate design for the problem you’ve identified.  As a professional engineer, you will be expected to be able to explain your idea, and why it is the right solution, to a range of audiences.  This might be your boss at work or the local community which you are working in.

Clear communication is vital here! Consider the use of images, diagrams, videos and models as well as the written and spoken word to get your idea across. Remember that you might need to use different techniques to to communicate your idea to different audiences. Not everyone will be interested in all the details but also know who will be (your academics for example!). Outlining the process you have gone through should assure people that you have taken logical steps to reach your proposed design and that you are confident it is appropriate.

The challenge you have been set is based on a real place, where real people are facing real issues. Our local partner organisations are keen to work with us to bring you this exciting project because they recognise:

  1. That it supports your development as an engineer who will make meaningful contributions to society in the future.
  2. The ideas you propose might help them address the issues the community faces and they might like to implement them.

To further support the appropriateness of your recommended idea and also provide our partner with key information should they wish to take your idea further, consider including information about the practical aspects of your recommended solution, such as:

  • Capital costs
  • Operational costs and any business models
  • What materials and skills are required and where these are expected to come from
  • How the idea will be made / manufactured / constructed
  • What maintenance and repair is expected
  • What training or education might be needed, for operation or use

Top Tip: Also informing your audience about what ideas you have rejected, and why, is helpful in building confidence that you have undertaken a thorough process.
