This position paper outlines the problems and risks of selecting COTS products. In particular, we highlight the challenges of the decision-making process where requirements specification plays an essential role to evaluate and compare products features. It is necessary to perform a careful balancing between requirements and COTS features. Customers may have to compromise on requirements not satisfied by any available product or request products modifications. We analyse the problems and risks arising in the selection process and review related work. We argue that a goal-oriented approach can support an effective balancing between requirements and COTS feature during the decision-making.
