The creative thinking process has three values to determine the effectiveness of the process.

The creative thinking process is a technique to generate and evaluate new ideas for solving problems or improving situations. The effectiveness of the creative thinking process can be measured by three values: novelty, usefulness, and feasibility1. Novelty refers to how original, unique, or different the ideas are. Usefulness refers to how well the ideas address the problem or opportunity. Feasibility refers to how practical, realistic, or implementable the ideas are. Generating a pre-determined number of new ideas for a business solution is not a measurement of effective creative thinking, as it does not reflect any of these values. The quantity of ideas is not as important as the quality of ideas in terms of novelty, usefulness, and feasibility. References: BABOK® Guide
