What We Do

Usability Testing & Evaluation

 

Usability Testing

The goal of usability testing is to provide developers with ideas on how to improve their products to better meet users' needs. 

User testing provides our team with real data for which to base our recommendations.  The value of the data is that it enables the users to have a voice and for that voice to be objective and neutral.

Exploratory Usability Tests

An exploratory test is used to explore the concepts behind a design with the users.  We do this through focus groups and interviews.

Assessment Usability Tests

An assessment test is used to determine the users' experiences with the interface during the low-fidelity and high-fidelity design stages.  An assessment test may focus on one aspect of the product through to the entire product. 

We typically ask between five to eight people who represent the target audience/end-user to perform tasks using the interface.  (The interface may be in paper form through to a working prototype.)  The feedback from the users tends to be qualitative and subjective, although we may seek to discover quantitative or objective measures during these activities as well.

Verification Usability Tests

A verification test is used to determine the overall usability of a product after implementation has taken place. 

We tend to gather quantitative and objective measures during these activities, although we still seek qualitative or subjective feedback from the users as well.  We typically use more than eight users during the verification tests to ensure we have enough data to perform statistical analysis.

We also use verification usability tests to benchmark the usability of a product.  This is essential for ensuring new designs are just as usable, if not more usable, than existing designs.

Comparison Usability Tests

Comparison tests are typically used to compare the usability of two or more versions of a design or to compare a competitors product against the client's.  Comparison tests are also used to discover user preferences between different options.  We gather a range of data and use eight or more users to ensure statistical validity.

Usability Research

Sometimes design questions arise during development that are not possible to adequately answer from the data gathered from previous user tests or from our team's experiences.  In this instance, we rely on research - typically driven by a hypothesis - into the problem domain to help provide a solution.

Usability Evaluation

We believe the best user experience information and feedback can be gained from the users themselves.  However, we are aware that this may be difficult given time and budgetary constraints.  Our team offers a wealth of usability experience and knowledge that can be utilised to gain maximum benefit from these types of constraints.

Rapid Evaluation

A rapid evaluation, typically performed by one or more of our team, is often used to evaluate a design - whether conceptual, low-fidelity, high-fidelity, or an existing implementation - quickly and effectively to identify any potential usability problems.

We encourage the use of a rapid evaluation in combination with user testing.  A rapid evaluation should be used to discover those creeping usability issues that tend to distract users from their goals.  We believe it is best these are quickly identified and removed before user testing takes place.

Heuristic Review

A heuristic review is similar to a rapid evaluation except our team uses a list of pre-defined heuristics with which to rate the product against.
