Phase 5: Live-System

Regular usability testing after a successful launch or during live operation of a product guarantee growing turnovers and satisfied users. A comparative review requires statistics on use and usability.

An interactive product can be successful only if it keeps pace with the users' requirements and takes into account changes in the market.

Development should not be concluded with the launch of a product. Rather, work on the product should be regarded as being a cyclic process that starts right from the beginning of every cycle and takes into account the results of the usability testing.

SirValUse offers various controlling and test methods for the measurement of user satisfaction, which

make it possible to measure the success of an interface over a fairly long time,
show the need for optimisation, and
derive recommendations for action.

In Phase 5, the following methods are predominantly used:

Competition Analysis Compares the products of major competitors with the own ones with regard to common usability dimensions.	Expert Review Neutral experts assess an interface.	Eye Tracking Eye Tracking enables to map the users' scanpaths and create "hotspot images" which show how much attention is paid to which areas of the interface.
Field Observation The product is observed being used in the everyday life of the participants.	Field Studies Participants use test objects over a longer period of time, e.g. settop boxes, mobile phones, etc.	Hybrid Testing Results in quantitative statistics and comprehensive qualitative recommendations.
Remote Testing Website users test internet pages at home or at the workplace.	Market Analysis Regular observation of web sites provides decision aids for adaptation to your strategy.	Online Research Data acquisition via the internet - highly suitable for international user groups or those that are difficult to reach.
Online Survey Accompanies user experience testing to clarify requirements and measure user experience.	Out of the Box-Testing Uncovers problems on use of equipment - from unpacking via installation to usage.	User Experience Controlling Regular quality control of an interface using specially developed characteristics.
User Experience Testing Through observation and enquiry we explore the positive and negative experiences had whilst using the interface. In focus: Usability Problems.

Depending on the project, further usability methods may be useful.
