Co-design, rapid prototyping and usability testing.

Project type: Product design sprint

Starting to support young people to self-care and take ownership of their sexual health, transforming how they engage with Brook services.

The sprint was used to test service user appetite and technical viability for a new digital platform. We looked to start momentum in migrating away from a face-to-face, paper-based system.


Data collection needed to be reframed and prioritised. An improvised exercise helped structure the — private and sensitive — content.

To test user comfort of a digital tool, the prototype needed to feel more realistic than an early draft or wireframe.


We managed to produce a branded, coded prototype. Test responses proved there was a willingness to use the tool and that the prototype was understandable and easy to use.

The output of the week — the prototype and test results — provided leverage for further funding.

Process and output

During the week we managed to cover:

  • Problem exploration and definition
  • Lean user research
  • Lean content mapping
  • Collaborative sketching
  • Rapid prototype: high-fidelity, front-end coded and responsive
  • In-person usability testing
  • Testing analysis and sprint report
