When designing the human-machine interface, there are often trade-offs between flexibility and consistency. In principle, for a certain software, the user's way of thinking should be consistent, and the way of operation and control should be consistent. Only in this way can the user's difficulty in using the software be alleviated, and the user unwittingly enters the unified thinking framework to apply the software correctly and smoothly. But this is only one aspect of the problem. On the other hand, the problem is that users are diverse, they have their own habits and hobbies, and they should be given some flexibility and freedom to choose the operation of certain functions.
For example, for convenience, someone likes to use the arrow keys to select a feature listed in the drop-down menu, while others prefer to use shortcuts because they are very fast. When designing software, we may wish to make both fish and bear's paw.
For example, for the color of the human-machine interface, some people pay attention to improving the efficiency of their work, and they like the bright and pleasing color interface; others choose to protect their vision and prefer black and white. When developing MIS software, programmers may wish to give users the choice of color.
