After design ideas are generated, teams vote on them to determine their priority and value. Two common methods for prioritizing design ideation ideas are:

- **One-Hundred-Dollar Test**: Team members receive a hypothetical \$100 to distribute among the ideas, forcing them to evaluate each design's relative value.
- **NUF Test (New, Useful, Feasible)**: Team members rate each idea on a 1–7 scale across three attributes: whether they have seen the design before (New), whether it solves a problem (Useful), and how practical it is to implement (Feasible).

Prioritizing Design Ideation Ideas

Ideation involves determining solutions to user problems that were discovered during the observation phase of the process. Designers should focus on the needs and desires of users in order to best address these points.

IDEO Human-Centered Design Process

The creative process of generating ideas (basic thoughts) to their development, actualization, and communication that can be conducted by one or many people.

Ideation

Observation is the first step of the IDEO design process. This is an attempt to understand the users through things such as behavior, pain points, and other experiences. Designers should be open to all creative opportunities. 

Observation in IDEO

A simple prototype is created through the rapid prototyping phase of the process and receives feedback from the target users. This is highly important for user centered design. Without the user, it is just design.

User Feedback in IDEO

Using the feedback received in the last phase of the IDEO process, make changes to your original rapid prototype. This phase should be repeated more than once in order to produce the best design and the designers should return to the user feedback phase after each iteration. Once the design feels fine-tuned, it is time to move on to the next phase. 

Iteration in IDEO

Once the design has been finalized, it can be finally implemented into the product. After implementation, designers should again begin to observe users and restart the entire process once new points or ideas come to the forefront. Remember that the focus should always be on user needs.

Design Ideation in IDEO

Prototyping refers to a process in which a product or system is built. There are three types of prototyping: rapid, working, and finished prototype.

Prototyping in IDEO

Includes the generation of new ideas (ideation) and the implementation of those ideas.
