OPTIMAL IDEATION EVALUATION RATIOS

The theory that different ideation-evaluation (I-E) ratios are optimal for creative problem solving in different fields of endeavor in organ izations is presented. Preliminary field data (n = 622), which support the theory, are reported. As predicted, higher I-E ratios were found for work classified as more problem finding in nature, such as researc h; lower ratios were found for work classified as more solution implem entation in nature, such as manufacturing; moderate ratios in-between were found for work classified as more problem solving in nature, such as nonprofit organization administration. Implications for training a nd for increasing the understanding of innovation in organizations are discussed.
