What does design for error mean?

Make it easier for people to discover the errors that do occur, and make them easier to correct. Don't treat the action as an error; rather, try to help the person complete the action properly. Think of the action as an approximation to what is desired.

What makes good design?

Good design is a concept defined by industrial designer Dieter Rams's principles: It makes a product useful and understandable, is innovative, aesthetic, unobtrusive, honest, long-lasting, thorough to the last detail, environmentally friendly, and involves as little design as possible. Designers strive for good design.

What is human error in UI?

Human error is usually result of poor design. Designers blame the users when something goes wrong but in a way they are blaming their designs. Blaming the person won't fix the problem as the same mistake is likely to be repeated by someone else. Of course, people make errors.
