Brainstorming

Introduction: Brainstorming

Brainstorming is a creative group technique used to generate many ideas in a short time. It encourages open thinking, free expression, and collaboration, making it a popular method in problem-solving, innovation, and Lean improvement projects.

Background

The method was introduced by Alex Osborn in the 1940s as a way to boost creativity in organisations. Since then, it has become one of the most widely used techniques in business, education, and design. Brainstorming is often used in Lean and Kaizen workshops to encourage teams to think beyond existing routines.

Key Elements / Features

• Free thinking – All ideas are welcome, no matter how unusual.
• Quantity over quality – The aim is to collect as many ideas as possible first.
• No criticism – Judging or rejecting ideas is delayed until later.
• Building on ideas – Participants can expand or combine each other’s suggestions.
• Group participation – Works best with diverse teams for different perspectives.

Applications / Examples

In a Lean project, brainstorming may be used to find ways to reduce waste. In product design, teams might brainstorm features for a new service. In education, students often brainstorm to prepare group projects or explore solutions to case studies.

For example, a Kaizen team in a hospital might brainstorm ways to reduce patient waiting times. Ideas could range from reorganising schedules to introducing new digital tools.

Relevance / Impact

Brainstorming supports creativity, teamwork, and engagement. It helps teams quickly explore a wide range of options before moving into analysis and selection. When combined with tools like ADAM or prioritisation methods, it becomes a powerful driver of innovation and improvement.
