The purpose of this present research is first to analyze how the process of ideation has unfolded in community-supporting platforms, exploring ideation patterns and thereby the identification and analysis of how task characteristics that influence the contribution performance in ideation projects. Building a model based on task design theories for task characteristics and problem-solving theory, this study is addressing this aim with an empirical analysis of 335 ideation projects that vary based on task characteristics. The results from a negative binomial model indicate that while reward and specified task topics have a positive impact on the success of ideation; sector information as an alternative task characteristic has an inverse effect.
