The primary objective of testing the effectiveness of a new control before implementation is to ensure that risk is mitigated by the control. A control is a measure or action that is taken to reduce the likelihood or impact of a risk, or to increase the likelihood or impact of an opportunity1. Testing the effectiveness of anew control before implementation means verifying whether the control can achieve its intended purpose and objective, and whether it can address the risk adequately and appropriately2. Testing the effectiveness of a new control before implementation helps to avoid wasting resources, time, and effort on implementing a control that is ineffective, inefficient, or unsuitable for the risk scenario. It also helps to ensure that the control does not introduce new or unintended risks, or adversely affect other controls or processes3. The other options are not the primary objective of testing the effectiveness of a new control before implementation, as they are either less relevant or less specific than ensuring that risk is mitigated by the control. Measuring efficiency of the control process is a secondary objective of testing the effectiveness of a new control before implementation. Efficiency refers to the optimal use of resources to achieve the desired outcome4. Measuring efficiency of the control process means evaluating whether the control can achieve its objective with the least amount of cost, time, and effort. Measuring efficiency of the control process helps to optimize the performance and value of the control, but it is not the main reason for testing the effectiveness of a new control before implementation. Confirming control alignment with business objectives is a tertiary objective of testing the effectiveness of a new control before implementation. Alignment refers to the consistency and coherence of the control with the goals and strategies of the organization5. Confirming control alignment with business objectives means ensuring that the control supports and enables the achievement of the organization’s mission, vision, and values. Confirming control alignment with business objectives helps to integrate the control with the organization’s culture and governance, but it is not the primary reason for testing the effectiveness of a new control before implementation. Complying with the organization’s policy is a quaternary objective of testing the effectiveness of a new controlbefore implementation. Policy refers to the set of principles and rules that guide the organization’s decisions and actions6. Complying with the organization’s policy means adhering to the standards and requirements that the organization has established for implementing and operating controls. Complying with the organization’s policy helps to ensure the quality and consistency of the control, but it is not the main objective of testing the effectiveness of a new control before implementation. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 2, Section 2.1.8, Page 61.
