What kind of decision-making method does brainstorming belong to? What are its shortcomings?

Brainstorming (BS method) is also called intellectual stimulation method, or free thinking method (talking, talking and brainstorming).

Brainstorming comes from the word "brainstorming". The so-called brainstorming, originally used in psychopathology, refers to the mental disorder of mental patients. Now it is synonymous with unrestricted free association and discussion, with the purpose of generating new ideas or stimulating innovative ideas.

Brainstorming is a method to stimulate thinking, which was first proposed by American creative scientist A F· Osbourne in 1939 and officially published in 1953. This method has been practiced and developed by creative researchers all over the world, and a number of inventive technologies have been formed, such as Osborne's intellectual incentive method, dictation intellectual incentive method and card-type intellectual incentive method.

In group decision-making, because of the psychological interaction of group members, it is easy to succumb to the opinions of authority or the majority, forming the so-called "group thinking". Group thinking weakens the critical spirit and creativity of the group and damages the quality of decision-making. In order to ensure the creativity and improve the quality of group decision-making, a series of methods to improve group decision-making have been developed in management, and brainstorming is one of the typical methods.

Brainstorming method can be divided into direct brainstorming method (usually referred to as brainstorming method) and questioning brainstorming method (also known as anti-brainstorming method). The former is a method to stimulate creativity and generate as many ideas as possible in expert group decision-making, while the latter is a method to question the ideas and schemes put forward by the former one by one and analyze their practical feasibility.

When brainstorming is used to organize group decision-making, relevant experts should be concentrated to hold a special meeting, and the moderator should clearly explain the problems and the rules of the meeting to all the participants, and try his best to create a harmonious and relaxed meeting atmosphere. Generally, opinions are not expressed, so as not to affect the free atmosphere of the meeting. Experts are "free" to propose as many schemes as possible.

Brainstorming should follow the following principles:

1. The principle of out-of-court judgment. The evaluation of various opinions and plans must be put in the final stage, and it is not allowed to criticize and evaluate other people's opinions before this. Take any idea seriously, whether it is appropriate or not.

2. Welcome to express your opinions and speak freely. Create a free atmosphere and inspire participants to put forward all kinds of absurd ideas.

3. pursue quantity. The more opinions there are, the greater the possibility of producing good opinions.

4. Explore ways to learn from each other's strengths and improve. In addition to putting forward their own opinions, participants are also encouraged to supplement, improve and synthesize the opinions already put forward by others.

Disadvantages of brainstorming:

Of course, costs (time, expenses, etc. ) the brainstorming is very high. In addition, brainstorming requires participants to have good quality. Whether these factors are satisfied or not will affect the effect of brainstorming.
