Design principles are the standard of design that can be used to guide the design and measurement of the pros and cons of the design. A person who writes MRD will first consider using a sentence as a design goal, describing what needs or what the user wants to do, and then writing three to five design principles to meet the needs of the user.
For example, in the design of a Purchase lottery error page, designed to reduce user frustration. That design principle can be:
1, provide users with easy to understand information.
2, according to the error situation to provide useful information respectively.
3, Guide users to continue to browse other pages.
The above principles, incidentally, are described in conjunction with the following design methods for guiding design:
according to principle 1, the design of the interface will avoid the use of error parameters, ordinary users do not understand these professional terms.
according to Principle 2, a specific study of the error situation is required. For example, the server in the adjustment, the time period can not buy, the phone because of information for a certain period of time did not get the server feedback, or because the user's account balance is insufficient and so on.
according to principle 3, the user is directed to continue to use. For example, because of the account balance is insufficient, you can remind users to recharge, first purchase a part of the use of other credit card payment or return to the home page.
Based on the principles of design, the idea will be very clear. If it is teamwork, first divergent thinking, and then the design principles will be clear to facilitate the team to reach early consensus and in the appropriate framework to continue the discussion. As A/b scheme evaluation, can be compared to the design principles, such as a scheme to meet the principle of 1&2&3,b scheme to meet the principle of 1&2, that natural selection a scheme. The principle can also have priority, such as principle a scheme satisfies the 1&2,b solution to meet 2&3, principle 1:3 is more important, that chooses a scheme.
As for what is the design principle can study the interactive design of existing "common sense" or Google, such as the design principles of large companies, the purpose of writing principles is to grasp the focus, targeted design, too many principles, difficult to grasp. Some common sense or consensus content also need not be used as a design principle, such as the interface to have the sense of beauty and for touch-screen phone design to be easy to click, unless the product positioning is to focus on doing this work.
Design principles can not be copied, by their own research excellent products and daily work slowly accumulated. When the design requirements are too much to control the existing design ideas, then introduce design principles. Design principles can improve the efficiency of work, but if introduced prematurely, will limit the designer's divergent thinking, kill a lot of good ideas.
Design principles are subject to user needs and product positioning factors such as the impact, can be said to carry out the design of the guiding ideas, will be reflected in the product details, to maintain product consistency. Write down the design principles, even if the design is biased, it is easy to find their own where to make mistakes, and constantly exercise their own design awareness.
When you have mastered this approach, the focus is to study specific products and how to implement these design principles from the details.
