User interface prototype is a sketch of website or app, created for assessing the usability before investing time and money into further development.

Depending on project specifics, prototypes of different complexity are created. They can be quick sketches on paper, digital wireframes or detailed, high fidelity drawings. Prototype creation is based upon the user research, carried out beforehand. Active involvement of the client is a must - it improves mutual understanding and reduces errors. Prototype development is an iterative process: sketch, customer comments, improvements, usability test, improvements…

You will get a prototype, ready for usability test and documentation for its further development, if necessary.
