Talk about the antecedents and consequences of heuristic evaluation

Recently, she turned over some of the heuristic evaluations to professional collections emanating from some industry conferences over the years. The general idea is to start with the user research and existing principles, and then perform the assessment and conclude. The structure of the article is very rigorous (perhaps say eight shares?), But after reading the evaluation results (list of issues and optimization suggestions), found no connection with the previous research output, little wonder, if not, why research? Where is the result?

Let's briefly talk about the significance of the assessment.
The general optimization product routine is nothing more than "Discovery"> "Define"> "Design"> "Release", and then enter the next "Discovery", so the cycle. It can also simply be described as "finding a problem"> "solving a problem." In order to "solve the problem," we first "find out the problem." The reason is very simple. And "heuristic evaluation (heuristics are experiential and so called 'empirical evaluations') is a" cheap "way of" spotting problems, "and the output of the assessment is a list of issues and suggestions for subsequent design Optimized sources of inspiration and decision making.

To talk briefly about what people to assess?

Forgive me really do not understand the "expert evaluation" and "heuristic evaluation of the difference between the" expert evaluation "assessors more professional? Conceptually drilled tip friend ask me to teach. Three years ago, Patriarch Nelson named three categories of people in Usability Engineering's description of the impact of assessors' knowledge, while Usability Neophytes has some computer knowledge but no knowledge of usability. An "individual expert" is a usability professional, But not an expert in the field of interface applications, while "dual experts" have both usability expertise and domain knowledge in the relevant interfaces. The novice evaluator performed the worst, the double expert performed the best, and the usability professional should be as assessable as possible. Collaborative assessment methods can also be used to allow user representatives, product developers, and usability experts to work together to make up for their respective weaknesses.
Good to talk about the idea of ​​assessment and the problems I found.

Most people's thinking is basically "clear user"> "implementation evaluation"> "finishing results."

Nelson said:

Heuristic Evaluation is an usability engineering method used to discover the problems of usability in user interface designs that make these issues a part of the redesign process. Heuristic evaluations include having a small batch of evaluations Personnel evaluate the interface and determine whether the interfaces meet the established usability rules (ie, Heuristics). "

The concept emphasizes that "performance appraisal" is based on existing usability rules, availability rules are indispensable basis as a universal principle, and now some companies have their own principles or evaluation models (more for their own products Targeted). From personal experience, the usability principle alone relies on more operational usability issues, which often overlook the user's goals and forget about the "validity" of the three elements of availability (the other two are " Efficiency "and" Satisfaction ", ISO9241). If a feature is "invalid" for the user, it is useless to be interactive. Therefore, the basis of assessment in addition to the principle of availability, there are target users. If the usability principle is the general experience of all people (users), the target user is the specific design basis of the product being evaluated.

Therefore, the first step "clear user" not only clearly assess the principle, but also clear who the user and the relevant use of the scene to determine the content and manner of implementation of the assessment, but also to make the assessment results reasonable, which is actually a very large user Research process.

In practice, many people really do according to this idea, so I concluded in many projects, professional articles inside, from the beginning to see a variety of beautiful persona, account of user characteristics, behavior patterns, but not To know why, just after the explanation does not matter with the back of the contents of the assessment seems to lack some pertinence.

where is the problem?

Perhaps it is that "heuristic evaluation" is a subjective process of assessment in which factors with too many individual evaluators exist and the result of the evaluation is also influenced by the evaluator's ability. The beginning of a good idea, patted his chest and said "I am the user, I have empathy", and then the process of deformation, the user forgotten. Problems such as "usability testing", which are primarily user-oriented, are less of a problem, and subjective evaluations do tend to fall into their own world. The difference between assessors ability is an objective phenomenon, we can only do the best, but way, we also do some homework to remind ourselves. Maybe we can do these things:
1 time thinking "this feature right?"

"Do the right thing first and then do the right thing." "Choose the right ladder first and then climb." "Efficiency first is efficiency." All is a truth. Products are made up of functions that are in a form that meets the needs of the user. If the function itself does not help the user, do not bother with thinking about how its usability improves. For example, a registered interface in addition to the form of boring information, these are noise, but also to study their visual level? Our judgment based on the results of the previous user research or principles, think I am a user, I need these things? What do I need more? The result is questioning certain features and even suggestions for unknown features.

2 For the list of questions combed, add a column "Notes."

What is the basis behind this question? What is contrary to what principle, contrary to what the user's goal. such as:

However, we all try to act as users from the perspective of the user. Since the beginning of the user, good start to end, the end of the user. Do not start with the user, and finally become ourselves.
