It is so called on the analogy of the increasing size of a snowball when rolled down a snow-covered slope. Snowball samples begin from a core of known elements and are then increased by adding new ideas and solutions.
It involves concentrating groups of ideas pertaining to the same problem and assigning them a theme. This method is often used where there is no available sampling frame of new fiild or process.

Procedure Steps

1. One slip of paper is used per idea generated or possible solution offered
2. A meeting is set up of up to 5 people. The slips of paper are viewed and then grouped ‘like with like’.
3. Duplicates can be created if the idea is relevant to more than one group.
4. Patterns and relationships in the groups are observed.
