Purposedifferent | When loud voices or hierarchy distort the idea search, the method creates a quiet entry into joint development. It gives everyone thinking space and gathers contributions without social brakes, making diversity more visible and easier to build on. | When features need to be distinguished by their effect on satisfaction, it makes expectations and surprises comparable. It separates basic needs, performance contribution, and delight. | When a workshop has produced too many options and the group needs to condense quickly, dot voting makes preferences visible in a short time. It bundles individual votes into a solid signal for the next selection. | When loud voices could dominate a round, Nominal Group Technique protects individual thinking time from group effects. It collects ideas separately first and only then enables shared weighting. |
