Decision trees, weighted matrix, and context diagrams are tools and techniques that can help the business analyst to maximize business value while establishing the requirements baseline. Decision trees are graphical representations of possible outcomes and choices based on certain conditions or criteria. Decision trees can help to evaluate and select the best option among multiple alternatives based on their expected value or risk. Weighted matrix are tables that assign scores and weights to different factors or measures to compare and prioritize them. Weighted matrix can help to rank the requirements based on their alignment with the business objectives, benefits, costs, risks, dependencies, urgency, etc. Context diagrams are visual models that show the boundaries and interactions of a system or product with its environment. Context diagrams can help to define the scope and stakeholders of a project, as well as their needs and expectations. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline (2019), page 11-12; Business Analysis for Practitioners: A Practice Guide (2015), page 66-69.

Managing solution scope is the task of ensuring that the solution meets the agreed-upon requirements and delivers the expected value to the stakeholders. Managing solution scope involves analyzing the impact of any changes to the scope, assessing the feasibility and risks of the changes, and obtaining approval from the stakeholders before implementing the changes. Managing solution scope can help the business analyst to identify the impacts, dependencies, or risks associated with the addition to the scope. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline (2019), page 14; Business Analysis for Practitioners: A Practice Guide (2015), page 83.

The business analyst could use the expected vs. actual results technique to iteratively validate the solution. This technique involves comparing the expected results or outcomes of the solution with the actual results or outcomes that are observed or measured after the solution is implemented. This technique helps to verify that the solution meets the requirements and the acceptance criteria, and to identify any gaps, issues, or defects that need to be resolved or corrected. References: PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline1, page 25; Business Analysis for Practitioners: A Practice Guide2, page 141.

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.
