Design and Development (SPE301)

10 credits

Aim of this module

To introduce the trainee to the development life cycle, from user specification through to validation and verification. The trainee will apply the methodology to a small project or component of a larger project in clinical  measurement,  information  and  communication  technology  (ICT)  or  medical  device  design and development.

  1. Produce a user specification from a user concept.
  2. Undertake a literature review to inform the design process.
  3. Translate the user specification into a design using CAD software. 
  4. Design and undertake verification and validation tests on a design. 
  5. Critically evaluate their proposed methodology.
