Smartpedia: Brainstorming is a creativity technique in which a group of people work together to try to solve a task by collecting and developing ideas.
Brainstorming – the joint development of ideas in a team
The inventor of brainstorming Alex Faickney Osborn paraphrased his creativity technique as “Using the brain to storm a problem”. It is a format for groups to try to solve a task or problem by brainstorming together and then evaluating ideas.
Osborn based his development of brainstorming in 1939 on the Indian Prai Barshana technique, which has been around for about 400 years. Later, brainstorming was further developed by Charles Hutchison Clark as a method for finding ideas in a team. Today, brainstorming is considered a classic of creativity techniques, used in product and service development, in all conceivable organisational areas and organisations, or when solving problems.
Brainstorming follows a clear process of
- execution with idea generation and idea evaluation as well as
In the course of brainstorming preparation, the team is put together on the basis of the problem, e.g. employees of a specialist area, experts of a subject area or external colleagues.
At the beginning of the execution, the brainstorming rules, the specific procedure and also the timebox (e.g. 30 or 45 minutes) should be given. In addition, it is advisable to name a minute-taker – in practice often identical to the moderator.
The moderator presents the problem. The problem should be visibly presented on a blackboard, a flipchart or a whiteboard at all times, so that the participants can more easily keep the required focus during the brainstorming session.
Now the participants can spontaneously give their ideas for solving the problem or finding a solution. Ideally, the participants inspire each other so that other ideas can be derived from individual ideas. All ideas have to be documented immediately. It is important to make sure that the information is not “translated” or “shortened” by the minute-taker / moderator. They should be documented as originally formulated by the participants and not “alienated”.
The idea generation is followed by the joint idea evaluation. For this, the ideas are grouped, analysed, filtered and evaluated. The aim of brainstorming is to create a list of the best ideas or proposed solutions in order to ideally realise the most promising one(s). The idea evaluation should also be provided with a timebox (e.g. 30 or 60 minutes).
At the end it is necessary to describe the further procedure: who does what until when, how do possible next steps look like, when do the participants possibly meet for a second round etc.?
In the course of the follow-up, the results are prepared and made available to the participants. It is also recommended to communicate new information, findings and developments on a regular basis.
For brainstorming to work, there are some simple sonic rules to follow:
- The criticism of ideas and thoughts is forbidden to every participant (and thus also to the moderator or the minute-taker). General criticism of individual idea providers is also not permitted; the aim is an appreciative, open and fair communication to solve a problem or task.
- Any idea – as unlikely as it may sound – is a good idea.
- Ideas expressed may be further developed by all participants. There is therefore no copyright on ideas.
- Clear time limits as a timebox (e.g. 45 minutes for idea generation and 30 minutes for idea evaluation) and the goals of individual sessions must be communicated.
- Every participant can, but does not have to, participate.
Tips for conducting brainstorming sessions
There are a number of tips that have proven useful in practice:
- The participants should be clear about the process, the rules, the question and the objective as well as the timebox.
- Sometimes the questions are too extensive. In this case, it is advisable – also in the course of a session – to extract sub-questions and address them individually. If neither all sub-questions nor the general initial question can be answered within a session, a new date for a new exchange should be arranged.
- In order to keep to the timebox, there should be a timekeeper who also ensures that the agreed time is kept to even if there is a lively exchange among the participants.
- The climate during the collection and subsequent evaluation of ideas is important for the quantity and quality of the contributions. Of course, the moderator can try to have a facilitating effect, but it is the responsibility of all participants to adhere to the rules and, if necessary, to remind others in a friendly manner to follow them.
- Interdisciplinary brainstorming increases the understanding between roles, staff and areas on the one hand and offers different perspectives on the issue on the other.
- Visualising the contributions on a whiteboard or pinboard facilitates the exchange and promotes the refinement of ideas.
- The processing of the results and the derivation of measures round off the exchange. Here, too, the moderator and/or the timekeeper is asked to set aside enough time for this part of the meeting.
- In some situations it can be useful to make minor adjustments to the procedure. For example, in “Round Robin” the person who expresses an idea first then decides whether the person sitting to his or her left or right should express the next idea; this ensures that all participants have their say. And in “Silent Reflection”, participants are given the opportunity to jot down ideas in silence and for themselves before they are communicated verbally.
And last but not least: brainstorming may be fun, but it is not a joke. It is often about solving problems, enhancing products or services. The ideas are a means to an end. It is therefore always advisable to make sure that ideas are also implemented and that the implementation is discussed in the group of participants at a later point in time and, if necessary, also evaluated. Corresponding findings can be recorded in lessons learned, for example.
Brainstorming advantages and disadvantages
Brainstorming offers a number of advantages:
- The rules are easy to understand.
- The process is easy to implement with practice, an experienced moderator, a common goal and mutual consideration.
- The effort required for preparation, implementation and follow-up is kept within limits.
- The associative and non-judgmental collection of ideas is a great advantage of brainstorming.
- The joint promotion of divergent, diverse ideas is often a lot of fun.
However, there are also a number of challenges or disadvantages:
- Introverted employees often find it difficult to express thoughts and ideas in “public”.
- “Frequent speakers” or “loudspeakers” quickly negate the common purpose of brainstorming.
- Supervisors often communicate non-verbally what they think of the ideas and statements of individual participants. They may subsequently hold back and important perspectives are left out.
- Participants also often start judging opinions and thus consciously or unconsciously destroy the format and an exchange at eye level.
Adhering to the rules sounds relatively simple in theory, but in practice it is not always easy to implement. This is where the moderator is often particularly challenged. Without a good moderator, it is difficult to organise a successful brainstorming session. If he or she does not intervene in a moderating role, extroverted employees and/or supervisors will usually get their way and many ideas of more introverted employees will remain unspoken. The goal of brainstorming is missed. As an alternative, many organisations use different variants or alternatives.
Variants and alternatives to classic brainstorming
Here is a list of some variants and alternatives that can be used to employ other forms of exchange, selected questioning techniques or defined structures:
- Brainwriting is a non-verbal creativity technique for brainstorming in which participants write down their ideas. The best-known variant is probably the 6-3-5 method.
- Braindumping describes the dumping of thoughts and ideas with the help of morning pages and task lists. So-called brain-netting and Idea Napkin work in a similar way.
- Reverse brainstorming is a format in which questions to be answered are formulated negatively and consolidated answers are turned into positive ones. Similar approaches can also be found in the headstand technique or the premortem.
- Round-robin brainstorming is a format in which all participants express themselves on a topic in a defined order (possibly in several rounds).
- 1-2-4-All is a format in which the number of participants per round is gradually increased. It is part of the so-called Liberating Structures.
- SCAMPER is a creativity method that uses a series of keywords and questions to facilitate the search for ideas. It is related to the Osborn checklist.
- Starbursting is a creativity method that uses questions to illuminate facets of a topic before seeking answers to the questions. Similar approaches can also be found in the 5-Why method or the 5W1H method.
This list can certainly be extended with further variants and alternatives.

Impulse to discuss:
Feedback from participants can improve the quality of brainstorming sessions. It might be worth taking a look at the ROTI feedback?
