“Expert review” is a professional term referring to a system audit conducted by usability experts. This audit is based upon scientifically validate assumptions and heuristic analysis. Along the examination the expert is going over the current interface or the preliminary prototype with the following guide lines:

• A comprehensive analysis of target users’ preferences

• Defining user behavioral patterns as it relates to system’s objective

• Analyzing logical flow of task performance and information structure in order to pinpoint major obstacles interrupting users from obtaining their goals

• Insuring a smooth and gradual shift from an old interface version to its upgrade (the methodology of upgrade implementation)

• Determining the right visual and contextual balance to match user preferences and insure their satisfaction

• Gaining users trust and reducing functional hesitation and confusion

• Insuring accessibility compatibility (taking users with physical disabilities under account in the process of logical and graphical design)

In the quest for valuable quantitative information regarding user behavior on web based platforms, “log file” data is the most available, cost-effective information source.

With minimum effort, every organization can diagnose and monitor interface efficiency regarding users satisfaction. Basically that information contains a full documentation of users tracks over sites pages. Such information can be the most viewed pages or the most common route chosen by users to navigate through the site.
In order to highlight the relevant information and figure out the right interpretation of all log file’s statistical charts, a careful and professional attitude must be applied based up on validate ‘user behavior’ assumptions. Along years of ‘log file’ analyses we have acquired some balanced and subtle observation tools enabling our many clients to tell the deference between an incorrect malfunctioning usage flow and an undesired unattractive one. So before jumping to any hasty conclusion...
