Assume you are working on a CAS (Conditional Access System) for Pay-TV that allows the access, selection and transfer of services and media to authorized users. Authorized users can choose their services through different channels: Web Customer Portal, IVR (Interactive Voice Response), Call Centre and SMS. The system uses a Smart Card to receive and decrypt the broadcasted encrypted control words which allow decrypting pay-per-view TV. Every authorized user must have a Smart Card and a Set-Top Box to view the contents. The following is an excerpt from the product risk analysis document:

Both likelihood and impact have been rated on the following scale: (1 ?Very low, 2 ?Low, 3 ?Medium, 4 ?High, 5 ?Very High). The required test environment and code have been delivered. All test cases for each identified product risk item have been written and are ready to be executed. The Database used to contain the Smart Cards is empty and so only new Smart Cards can be used during test execution. A Smart Card can only be activated if it has been previously pre-activated. This means the post- conditions for the execution of the test cases to test the pre-activation of the Smart Card are the pre-conditions for activation of the Smart Card. Which of the following statements represents the most effective contribution of the stakeholders to the completion of the failure mode analysis table?
