What is design? What a designer could do?

Who could be a designer? And what kind of activity could be called as a design?
Someone said, "everything is design, everything!" Some one said:” everybody is a designer.” I agree these words sometimes, maybe in everyday life or other discussions. But here, I’d like to say that “everything could be designed, and everyone could be a designer.” What’s the difference between them? I am trying to find my answer from three aspects: goal, process and skill.

Scene 1: One day, you accidentally entered an empty house. There was nothing in the house except one thing, and you never knew what the thing it was. You could do nothing to go out of the house without other people’s help. You picked up the thing, and tried to know what it is by knocking on different parts of it. You knocked on it continuously in order to let people get your signals asking for help. GOD! The sound you made was too melodic to be heard. Definitely you created a piece of great music at last even though you know nothing about the thing, the musical instrument. Yes, you created a piece of music, but you did NOT design it. There is no design goal about the music, and the outcome is not expected.

My opinion 1: A designer has clear goals for design works, functional, aesthetic, emotional…

A design has clear goals too, such as why the design is needed, and what problem a design work should solve.

Scene 2: Deliverymen delivered tons of furniture and decorations to the empty house. They have no professional knowledge about interior decoration, but they decorate their own houses very well. They fit all of articles in the house according some rules, such as the refrigerator was put in the kitchen, and the different furniture in same color and style were put in same room. The whole house looks great now. However, they did NOTHING about interior design, no matter the layout of the rooms was good or not, the color in one room was matched or not, and what special impression people could get from the style. You, as an interior designer, suggest that put all the things outside of the house, ask the owner what kind style s/he wanted the home has, investigate the structure of the house, provide a proposal about your design, test on if the proposal can get the result you want to create, make some change on the proposal, get to know if the proposal satisfy the owner or not, repeat some of the above steps, at last, get the house decorated. Well done? No, it is not enough. Beside of the color, layout, impression, there is much more need to think, such as convenience, comfortable.

My opinion 2: A designer has the ability to control the direction and make progress of a design.

A design should have its process to get matured.

My opinion 3: A designer has his/her responsibilities to a design, and all factors involved in should be considered by not other people, but designers. This is the difference between professional designers and people who just give a piece of opinion.

A design is about not only the things created, but also the influence on the context.

Scene 3: A new disabled family member is coming to the big house. New needs were asked, new conditions were generated…

My opinion 4: A designer has the skills to make some change to a design according the variation of the environment outside and conditions inside.

A design should keep change according the context.
