His name is Alex Osborn who first introduced the brainstorming and determined the conditions for its use in 1942. Brainstorming takes place in environments where there is no trial; it helps to create creative and original ideas.
Brainstorming can be defined as asking a group of people to think openly about the state of a topic or problem and to produce as many ideas as possible without worrying about whether it is logical.
It is a problem solving method that enables participants to use their imagination and encourage their creativity.
