NAF Technique

The NAF technique is a method for selecting ideas, where a new idea emerges from all the ideas that have already been gathered. This idea must be new, appealing, and feasible. The technique involves evaluating ideas and deciding whether to pursue and implement them. Additionally, the method helps identify alternatives and increases the chances of successfully implementing a new idea.

Organisation

  • Duration
    Short (up to 30 minutes)
  • Complexity
    Simple
  • Group size
    1 to 100 persons

This activity is suitable online.

Description Long

In the NAF method, solutions are analysed based on their uniqueness (new), attractiveness (appealing), and functionality (feasible). You should rely on your gut feeling during this process. To select ideas, they are rated on a scale from 1 to 10. The following questions are used to evaluate the ideas:

  • Uniqueness: How unique is the idea? If it isn’t unique, it’s probably not very creative.
  • Attractiveness: How appealing is the solution? Does it truly solve the problem, or only partially?
  • Functionality: How easy is it to implement? It may be an attractive solution, but is it truly feasible?

The following points should be considered after the selection:

  • If an idea is neither new, attractive, nor feasible, its implementation will likely be disappointing.
  • If an idea is new, attractive, but not easily implementable, it should be investigated further. Creative solutions might be found to improve its feasibility.
  • If the average attractiveness score of an idea is higher than 5, it should be considered for further evaluation. Additional research could increase the value of the idea.

Preparation

  • Prepare voting cards.
  • Select a person to vote, or choose yourself.
  • Online: Prepare a method for participants to visibly assign points to the ideas for everyone to see.

Execution

  1. The NAF method is explained.
  2. All ideas are first read aloud.
  3. Participants are asked to assign points for "new", "appealing", and "feasible", with 1 being the lowest and 10 being the highest.
  4. Each participant writes the points for all three criteria of an idea on a card.
  5. The cards are collected and placed next to the corresponding idea.
  6. This process is repeated for each idea.
  7. The points for each idea are totalled.
  8. Which ideas receive the most points for each criterion?
  9. In the group, all ideas that can be pursued further are discussed.

Hints from experience

  • Once the points are assigned, it's easy to identify the top ideas.
  • Each person should write their points on a separate card.
  • An idea may seem new, but it might actually be old: Give it 10 points if it's new and 1 if it's not.
