One of the most underestimated aspects of being a usability engineer is the mindset. To maybe no surprise, “mindset” is not mentioned in the IEC 62366-1 standard in usability engineering.  

The following video, which is a part of our online Introduction to usability engineering and IEC 62366-1 course will introduce the topic. 

Usability engineers as experts 

Most jobs and positions have experts in its particular fields – architects, mathematicians, doctors, who all know what is best for the problems or situations they are tackling. With usability engineering, the experts can be called process experts, because a process expert is, simply said, someone who knows the way.  

Consequently, the usability engineer does not have to be an expert on how a particular product is to be used. The usability engineer should be a process expert that knows the best steps to take and how to go from one step to the other. Usability engineers can be experts on specific matters, but they do not have to be. But for someone who only knows the process, one more thing needs to be added to be successful, and that is the user. 


The users as usability engineering experts 

The users in usability engineering are the subject matter experts. This is because they know the tasks, the environment, the social rules, both explicit and implicit, but most importantly – they know what they need. 

Your mindset as usability engineer

Users know the progress they are looking for. They know the goal and their destination, but what they do not know is the way. This is precisely why the usability engineer and the user make such a great team. Because one of them is the expert on the process, and one is the expert on providing input to the road taken.  

In order to design a great device, both experts are needed; process expertise and subject matter expertise. 

The task of the usability engineer is to build an environment of trust that enables the users to show what really matters to them. For that kind of environment to exist, there must be a respect towards the users, as well as sincere interest in what they have to say. 

Perhaps one of the most important skills of the usability engineer is that they refrain from trying to explain their own potential solutions to the users, but spend at least 80% of the time listening carefully.  


Rules for being a good usability engineer 

If there were hypothetical rules for user researchers and usability engineers, they could be summarised as: 

  • Be respectful 
  • Be interested 
  • Be neutral 

Being respectful is simply listening to the user, without trying to convince them to think otherwise, and especially without arguing. This also includes being exceptionally polite. 

The second rule, being interested, means being prepared to ask many questions designed in a way to help the usability engineer to understand the situation and the user’s point of view. The way the questions are worded is of great importance since they should be open and not guide them towards any particular answer or a conclusion. 

Finally, being neutral is all about realising that what the usability engineer thinks and how they feel is simply not relevant and important. It means constantly remembering that it is all about the user and their needs, regardless of whether the engineer likes what they hear or not. They are not supposed to judge or assess the situation. This is because it is very easy to change the reaction of the interview partner, leading to false results. 

To sum it up, great usability engineering includes two types of experts: the usability engineers themselves, and the users. When both parties stick to the rules and work towards the common goal, little could go wrong.
