The BA should select CRUD (Create, Read, Update, and Delete) matrix as the technique that would

be appropriate for determining how and who uses data across the identified processes. CRUD matrix

is a table that shows the actions that different roles or stakeholders can perform on data entities or

objects within a system or solution. CRUD matrix can help to define the data access rights and

permissions for each role or stakeholder, as well as the data dependencies and interactions among

processes.

The other options are incorrect because:

Option A is incorrect because stakeholder list, map, or personas are not techniques for determining

how and who uses data, but techniques for identifying and analyzing stakeholders. Stakeholder list,

map, or personas are tools that provide information about the characteristics, needs, expectations,

and influences of stakeholders. Stakeholders are individuals or groups who have an interest or stake

in a change or solution.

Option B is incorrect because data dictionary is not a technique for determining how and who uses

data, but a technique for defining and describing data. Data dictionary is a repository that contains

the definitions, attributes, formats, and relationships of data elements or objects within a system or

solution. Data dictionary can help to standardize and document the data requirements and

specifications for a solution.

Option D is incorrect because decision model is not a technique for determining how and who uses

data, but a technique for modeling and analyzing decisions. Decision model is agraphical

representation of the logic, rules, criteria, and outcomes of decisions within a system or solution.

Decision model can help to simplify and clarify the decision-making process and its impact on the

solution.
