Software components, both Commercial-Off-The-Shelf and Open Source, are being increasingly used in software development. Previous studies have identified typical risks and related risk management strategies for what we will call OTS-based (Off-the-Shelf) development. However, there are few effective and well-proven guidelines to help project managers to identify and manage these risks. We are performing an international state-of-the-practice survey in three countries - Norway, Italy, and Germany - to investigate the relative frequency of typical risks, and the effect of the corresponding risk management methods. Preliminary results show that risks concerning changing requirements and effort estimation are the most frequent risks. Risks concerning traditional quality attributes such as reliability and security of OTS component seem less frequent. Incremental testing and strict quality evaluation have been used to manage the possible negative impact of poor component qual ity. Realistic effort estimation on OTS quality evaluation helped to mitigate the possible effort estimation biases in OTS component selection and integration.
