A governance, risk, and compliance (GRC) solution is an integrated system that supports the management of governance, risk, and compliance activities across the enterprise. A GRC solution can provide benefits such as improved efficiency, consistency, transparency, andaccountability. The best justification to invest in the development of a GRC solution is to facilitate risk-aware decision making by stakeholders. By providing a holistic view of the enterprise's risk profile, a GRC solution can enable stakeholders to make informed decisions that are aligned with the enterprise's objectives, risk appetite, and tolerance. A GRC solution can also help to monitor and report on the performance and outcomes of the risk management program, and provide feedback and assurance to the board of directors and senior management. The other options are not as compelling as the facilitation of risk-aware decision making, as they may not directly contribute to the achievement of the enterprise's objectives or the management of its risks.
