Brainstorming

What is Brainstorming?

Methodologically, brainstorming is often divided into several phases:

1. 1. Finding and collecting: Here, participants gather ideas based on their established rules and guidelines for the brainstorming session. Simultaneously, the moderator visualizes the ideas on cards, sticky notes, a flip chart, or a PC application. Additionally, participants should have cards and pens so they can jot down their ideas. This phase ends when no one can think of a new idea. This is the case when no more ideas are expressed after a long pause.

1. 1. Sorting: Here, the ideas generated arbitrarily in Phase 1 are grouped into individual categories.

1. 1. Evaluation: After Phase 2, a clear collection of ideas is available to the participants. This serves as the basis for evaluating the ideas. While criticism of ideas was prohibited in Phase 1, it is now explicitly allowed. Ideas that are nonsensical or cannot be realized are sorted out. This phase can also be carried out in small groups.

1. 1. Planning implementation: After Phase 3, a collection of promising ideas has emerged. These must now be followed up. In Phase 4, the necessary steps for this are determined. An action plan can be created for this purpose.

Brainstorming is based on the principle of liberating the participants’ thought processes: evaluation, criticism, or immediate analysis of contributions are deliberately avoided during the ideation phase. This openness promotes a high quantity of suggestions and lowers the threshold for unconventional thinking. The ideas gained in the process later serve as the basis for the selection, prioritization, and further development of suitable solution approaches.

After brainstorming, the most promising ideas should be further detailed using the mind-mapping method.

Rules and Guidelines for Ideation

For brainstorming to be creative and effective, clear principles are followed during the ideation phase. The primary focus is the goal of opening up the broadest possible idea space before an evaluation takes place:

• • Quantity over quality: In the early phase, the number of suggestions counts, not their quality. Free association should be deliberately encouraged.

• • Freedom from evaluation: Comments, criticism, or categorization of individual contributions are initially deferred to avoid mental blocks.

• • Openness to unusual approaches: Even unconventional ideas or those that initially seem unrealistic are expressly welcome, as they can trigger new directions of thought.

• • Collective inspiration: Participants build on each other; ideas may be expanded, combined, or modified.

These guidelines create a safe space in which even immature or seemingly far-fetched thoughts can be expressed, which may later provide valuable impulses.

Success Factors for Effective Brainstorming

Whether a brainstorming session is productive depends heavily on the framework conditions and preparation:

• • Diverse group composition: Different perspectives, experiences, and ways of thinking increase the chance of innovative solution approaches.

• • Clear and understandable problem statement: A precisely formulated initial question helps participants develop their ideas in a targeted manner.

• • Consistent adherence to the rules: In particular, the prohibition of criticism during the ideation phase is crucial to avoid discussions and evaluations.

• • Visible documentation: If ideas are recorded visibly for everyone, a collective “memory” is created that facilitates further associations.

• • Supportive atmosphere: An open, appreciative, and pressure-free environment encourages the participation of all attendees.

• • Patient moderation: Even phases of lower dynamics should be allowed, as further ideas often emerge only after a delay.

Typical Risks

Despite its simplicity, brainstorming can lose its effectiveness if certain points are not observed:

• • Unclear methodological expectations: If it is assumed that all participants are familiar with the procedure and rules, misunderstandings can arise. A brief introduction is therefore useful.

• • Disadvantage for reserved participants: Introverted individuals often need more time to formulate ideas. Direct pressure to contribute can have an inhibiting effect here.

• • Time pressure: Severely limited time windows can restrict creativity, as more complex ideas or those requiring explanation may be lost.

• • Pseudo-participation: If brainstorming is used even though decisions have already been made, motivation for future creative contributions decreases.

• • Lack of follow-up: If ideas are collected but not pursued, this can lead to frustration and lower participation in later sessions.

Variants of Brainstorming

In addition to classic brainstorming, numerous variants have become established that are adapted to different group sizes, working methods, and framework conditions:

• • Individual Brainstorming:
    Idea generation takes place alone, following the same basic principles as in the group format. This variant is particularly suitable for quickly developing several solution approaches.

• • Philips 66 Method (Buzz Session):
    Large groups are divided into small teams of up to six people, who collect ideas for a limited time and then present their results in the plenary session.

• • Brainwriting and the 6-3-5 Method:
    Ideas are recorded in writing and systematically passed on or supplemented. These forms promote equal participation and are particularly suitable for reserved participants.

• • ABC Brainstorming:
    Ideas are collected based on given letters of the alphabet. This structure helps to open up new directions of thought, especially when searching for terms or associations.

• • Brainwalking:
    Several questions are processed in parallel as participants move between different stations and add ideas there. The method is well-suited for larger groups.

• • Brainswarming:
    Ideas are developed both goal-oriented (top-down) and resource-based (bottom-up) and merged visually to derive concrete solution paths.

• • Electronic Brainstorming:
    Digital tools enable text-based idea collection in virtual or hybrid teams, for example via online whiteboards.
