Evaluation and usability testing in its broadest sense can help us to understand the information needs and tasks of users and test whether these user requirements are supported. Testing will further identify areas where improvements can be made to increase the effectiveness, efficiency, ease of use, ease of learning and overall user experience. Evaluation can be iterated at each stage of a project?s lifecycle focusing, in the pre-development stage, on understanding users? requirements for the new services and, in testing throughout, on the appropriate measures of effectiveness, usability and satisfaction. In general usability work is regarded as ongoing with regular assessment to ensure that the service delivered is usable and useful. In this broad remit we can define the objectives of the study and select from amongst various methods to collect data and evaluate.
