The primary purpose of using key risk indicators (KRIs) to illustrate changes in the risk profile is to communicate risk trends to stakeholders. KRIs are metrics that provide an early warning of increasing risk exposure in various areas of the organization. By using KRIs to illustrate changes in the risk profile, the organization can communicate the risk trends to the stakeholders, such as the board, senior management, business units, and external parties, and enable them to take appropriate actions to manage the risk. Assigning ownership of emerging risk scenarios, highlighting noncompliance with the risk policy, and identifying threats to emerging technologies are other possible purposes, but they are not as important as communicating risk trends to stakeholders. References = ISACA Certified in Risk and Information Systems Control(CRISC) Certification Exam Question and Answers, question 12; CRISC Review Manual, 6th Edition, page 215.
