Return on investment (ROI) is a financial calculation that measures the profitability of a solution proposal by comparing its benefits and costs. ROI is expressed as a percentage or a ratio of the net benefits (benefits minus costs) to the total costs. ROI can help to determine which solution is worth investing in based on its breakeven point, which is the point where the net benefits equal zero, or the benefits equal the costs. The solution with the highest ROI has the lowest breakeven point, meaning that it recovers its costs faster and generates more net benefits over time. Discount rate is a financial calculation that measures the present value of future cash flows by applying a discount factor that reflects the time value of money and the risk of the investment. Discount rate can help to compare the present values of different solution proposals, but it does not indicate the breakeven point. Net present value (NPV) is a financial calculation that measures the difference between the present value of the benefits and the present value of the costs of a solution proposal. NPV can help to determine which solution has the highest value in today’s terms, but it does not indicate the breakeven point. Internal rate of return (IRR) is a financial calculation that measures the annualized effective compounded return rate of a solution proposal by finding the discount rate that makes the NPV equal zero. IRR can help to determine which solution has the highest return rate, but it does not indicate the breakeven point. References: BABOK Guide v3, Chapter 10: Techniques, Section 10.23: Financial Analysis, p. 529-531; Free CBAP IIBA Actual Exam Questions & Answers, Question 464.

A BA should identify any potential constraints that may affect the requirements or the solution and communicate them to the relevant stakeholders for resolution. In this case, the policies are a constraint that may prevent the implementation of the requirement or require a change to the policies. The BA should review the constraint with management and seek their guidance on how to proceed. The BA should not modify the policies or the requirements without proper approval or justification. References:

 A satisfy relationship is a type of traceability relationship that indicates that a model element (such as a requirement, a design element, or a test case) fulfills the intent of another model element (such as a stakeholder need, a business requirement, or a regulatory requirement). By using a satisfy relationship, the BA can link the solution components that implement the regulatory requirements and show how they meet the compliance criteria. References:

 A concept model is a visual representation of the business concepts and their relationships. It helps to clarify the meaning of the terms and concepts used in the requirements. However, different stakeholders may have different levels of understanding and interest in the concept model, depending on their roles and perspectives. Therefore, the BA should use an appropriate level of abstraction to support differing viewports, which are views of the same model that focus on different aspects or levels of detail. This way, the BA can tailor the presentation of the concept model to suit the needs and expectations of each stakeholder group, and help them understand the impacts to their respective daily tasks. References: BABOK Guide v3, p. 112-113; CBAP/CCBA Study Guide, p. 140-141.
