Creativity training is used by many organizations in an attempt to improve the innovativeness of their employees, yet there has been relatively little systematic evaluation carried out of the impact of such training. This study reports on the evaluation of the effectiveness of a theory
of inventive problem solving (TRIZ)‐based creativity training program in a major international engineering firm. Cross‐sectional, longitudinal and multisource evaluation strategies were used to assess the impact of the training on a sample of design engineers
(n = 123) and to make comparisons with nontrainees (n = 96). Results indicate that participation in TRIZ training led to short‐term improvements in both the creative problem‐solving
skills and motivation to innovate of engineers, and these were associated with longer term improvements in their idea suggestion in the workplace. There was variable support for the translation of these ideas into new innovations and improved performance at work as a result of the training.
Theoretical and practical implications for enhancing the effectiveness of creativity training interventions are discussed.
