An expert review aims to identify UX issues quickly
An expert review or website audit is an inspection method designed to identify usability problems in an online product or service. The review is carried out by a small group of usability experts (between 1 and 4), who analyse the product or service to identify any potential usability issues. This expert usability review is one of the few methods within the user-centred design process that does not involve any direct contact with end-users.
Why the formal method can be too rigid
The mainstream literature on this method often refers to the more formal method of Heuristic Evaluation, which refers to experts reviewing a graphical user interface for its adherence to common usability guidelines (or heuristics).
Whilst the Heuristic Evaluation is a common method used in more formal or academic circles, it could be argued that this method is too rigid and often fails to meet the needs of most clients. Assessing an interface by simply checking boxes to determine where it does or does not meet so-called usability guidelines does not place enough value upon the context of use, or the goals of the system. The evaluation relies solely upon usability guidelines that are often years old and the result of research on graphical user interfaces, which may be completely different to the one being reviewed.
Many guidelines are well-meaning, but when adhered to by the letter, they can often lead to poor usability decisions because the designer does not take into account their specific users, the context they will be using the system, and the goals of the product or service. Simply following guidelines can be misleading and can give a false sense of security that an interface is usable, when in fact it is not. For this reason, the following flexible expert usability review method is better suited to meeting customer and business needs.
An alternative approach
This expert review approach pays full attention to the context, the nature of the system being evaluated, and the goals of the business. The technique can be used more flexibly on screen-based technology as well as physical products and services and aims to fully understand user needs rather than reducing them down to a checklist.
Start with the end-user in mind
This method first requires an understanding of who the users of the system are and what the business goals are, so the initial brief is crucial. The expert develops the information on the end-users into user profiles or personas (if these have not already been provided) and works with the client to narrow down the personas into one or two priority users. Each priority user should then be looked at in more detail to outline their typical goals and scenarios when using the product or service. Once this has been done, the expert usability review can begin.
Always try to put yourself in the shoes of the user
For each of the priority users, the expert attempts to achieve the priority users’ goals with the product or service in question. By placing themselves in the shoes of the potential user, the expert will examine the interface in context to make recommendations that help the customer achieve their user goals and the product owner to better achieve their business goals.
The method requires an expert to carry out the review to provide the experience (of conducting usability tests and user research) to fully predict the potential pitfalls in the user journey. The most important skill of the expert is to extract their own personal perspective away from the review in order to provide an objective analysis.
Businesses are able to get fast, low cost, independent feedback at almost any stage of their product or service development life-cycle. This is supported by detailed feedback on each step of a typical user journey along with a more strategic perspective on how the product or service may need to refocus upon customer needs in order to truly fulfil its business strategy.
The more traditional heuristic usability evaluation can be inflexible in many modern projects as it relies solely upon the experts to analyse the interface for its adherence to usability guidelines. Whilst usability guidelines can be extremely useful to help guide decisions, they can also be dangerous to follow without taking into account the full context of use. An alternative method that takes into account the full user journey, and the goals of the product or service, is better suited to today’s business needs.
Although the expert usability review does not offer the level of confidence or depth that watching real users does, it is an extremely useful tool to offer independent advice quickly and easily on a product or service. As this method is quick to conduct it requires less budget than a usability test and can therefore be used multiple times throughout a project life-cycle.
