Internal rate of return (IRR) is a technique that calculates the annualized rate of return of an investment or a project. IRR can help the business analyst to determine the estimated growth rate of potential solution options by comparing the present value of the expected cash inflows and outflows of each option. IRR can also help to select the option that has the highest rate of return and exceeds the minimum required rate of return or the cost of capital. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline (2019), page 11; Business Analysis for Practitioners: A Practice Guide (2015), page 66.

The decision-making process in the business analysis plan defines how decisions will be made regarding the requirements and the business analysis approach. It specifies the roles and responsibilities of the decision makers, the criteria and methods for making decisions, and the process for resolving conflicts and disagreements. Having a clear decision-making process can help the business analyst facilitate the requirements workshop and reach an agreement among the stakeholders with different points of view and priorities. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline, page 13.

 The business analyst can determine the impact of a new requirement on existing requirements by reviewing the requirements traceability matrix. The requirements traceability matrix is a tool that tracks the relationships and dependencies among the requirements, as well as other project elements such as design, test cases, risks, or issues. By reviewing the requirements traceability matrix, the business analyst can identify which existing requirements are affected by the new requirement and assess the impact of the change on the scope, schedule, cost, or quality of the project. Performing a stakeholder analysis is not a way to determine the impact of a new requirement on existing requirements, as it focuses on identifying and understanding the needs, expectations, and influence of the stakeholders, not the requirements. Using time-boxing to defer the new requirement is not a way to determine the impact of a new requirement on existing requirements, as it postpones the analysis and implementation of the new requirement until a later iteration or phase of the project. Updating the use case documentation is not a way to determine the impact of a new requirement on existing requirements, as it only reflects how the new requirement affects one aspect of the solution functionality, not the entire project. References: Business Analysis for Practitioners: A Practice Guide 1, page 161-162; PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline 2, page 19.

According to the PMI Guide to Business Analysis, a Pareto analysis is a tool that helps to prioritize problems or causes based on their frequency or impact. It is based on the Pareto principle, which states that 80% of the effects come from 20% of the causes. A Pareto analysis can help to identify the high-priority changes needed to improve a service by showing which problems or causes account for most of the complaints or dissatisfaction. A work breakdown structure analysis, a flowchart, and a cause-and-effect diagram are other tools that can help to analyze a service, but they do not necessarily help to prioritize the changes needed to improve it. References: PMI Guide to Business Analysis, page 145-146.
