User Research Methods

This study explores a range of research methods that may be employed during a UX project. These methods may be used: at the beginning of a project to gain an understanding of the needs of the user and the tasks they need to perform; during a project to evaluate the current design iteration; and after a product has shipped to gain an understanding of how well it is performing relative to the product goals


For this report three different methods of user research are being examined.

One method has been chosen from each of the three different phases of the product development lifecycle – Strategise, Execute and Assess.

The three methods to be compared are

  1. Diary Studies (stategise phase)
  2. Tree Testing (execute stage)
  3. A/B Testing (assess stage)
