Description Long
The group evaluates the solution that has been provided, on a four-point scale, according to the defined criteria.
Seven criteria: feasible, realistic, innovative, effort required, potential for development, personal dedication (How much do I want to be part of the planning and realisation team?), emotional impact on end users.
A list that ranks the solutions is created, and subsequently discussed and reflected upon.
Illustration
Preparation
- Create worksheets with a radar chart.
- Print an adequate number of copies, at least A3, (if they are evaluated individually beforehand, A4 sheets might suffice).
Execution
- Depending on the variation: For the “together” variant, hand it up where it is visible to everyone. For the “individual” variant, hand each participant a copy.
- Remind participants to evaluate honestly and independently.
- After covert evaluation, the workshop leader collects the individual evaluations and transfers them to a large sheet of paper, and hangs it up somewhere, where it is clearly visible.
- Prepare a brief presentation of the two best ideas.
Hints from experience
- Ask whether everyone understands the criteria.
- If possible, name indicators for each criterion, that illustrate that the requirements have been met.
- If there is an open, trusting atmosphere, evaluate openly as a group. However, if, for example, the group is defined by hierarchies, competitiveness or a lack of trust, get the individual results anonymously first, and then superimpose them over each other anonymously.
- Even rating scales (e.g. four-point scales) require participants to make a decision. Odd rating scales permit participants to remain ‘neutral’.
- This method can already be used to evaluate and select ideas, in order to develop solutions from the results (Closing 1).
