Produce a list of usability problems, categorised by importance (use
post-it-notes to sort the problems), and an overview of the types of
problems encountered.
Arrange a meeting with the project manager and developer to discuss
whether and how each problem can be fixed.
If measures have been taken, summarise the results of the satisfaction
questionnaire, task time and effectiveness (accuracy and completeness)
measures.
If a full report is required, the Common Industry Format provides a good
structure.
