A tornado diagram is a type of bar chart that shows the effect of varying different input parameters on an output variable. It is often used in sensitivity analysis to compare the relative importance of different factors or uncertainties that affect the outcome of a decision, project, or model. A tornado diagram typically has a horizontal baseline that represents the base case value of the output variable, and vertical bars that extend to the left and right of the baseline to show how the output changes when each input parameter is varied from its minimum to maximum value, while holding all other parameters constant. The bars are usually sorted by their length, creating a shape similar to a tornado. The longer the bar, the more sensitive the output is to that input parameter. A tornado diagram can help identify the key drivers of the output variable, as well as the parameters that have little or no impact. 

The BA should inform the stakeholders that the regulatory requirement takes precedence over other requirements, because it is a mandatory constraint that must be satisfied by the solution. The BA should explain the rationale and implications of the regulatory requirement, and how it affects the other requirements and the solution scope. The BA should also seek to resolve any conflicts or issues that may arise from the stakeholders, and ensure that they understand and accept the priority of the regulatory requirement. Measuring the value of the other requirements against the penalty of not meeting the regulatory requirement, comparing the regulatory requirement to the recommended solution, or determining a means to work around the regulatory requirement are not the best options, because they do not address the root cause of the problem and may result in non-compliance, legal liability, or stakeholder dissatisfaction. References:

Diagrams are visual representations of information that can be used to define boundaries for business domains, categorize and create a hierarchy of items, and show data sources and their relationships for specific audiences. Diagrams can include various types of models, such as context diagrams, class diagrams, data flow diagrams, entity relationship diagrams, use case diagrams, and swimlane diagrams. Diagrams can help the BA to communicate complex information in a clear and concise way, and to elicit, analyze, and validate requirements with stakeholders. References: CBAP Handbook, CBAP Study Guide, BABOK Guide

A run chart is a line graph that shows data points plotted in the order in which they occur. It shows the history and pattern of variation of a process over time. It can be used to perform trend analysis, which is the examination of data over time to identify patterns, changes, or shifts in the process. A run chart can help to identify process stability, variation, and improvement opportunities. A run chart is also known as a line chart, a trend chart, or a time series plot. References:
