A governance approach is a technique that helps to define and establish the roles, responsibilities, authorities, and decision-making processes for the business analysis work. A governance approach identifies the stakeholders who have the power and influence to approve, reject, or modify the requirements or the solution, and the criteria and mechanisms for obtaining their approval. A governance approach can help the BA to identify the stakeholder who can approve access to the database, as it can specify who owns the database, who has the authority to grant or deny access, and what are the steps and procedures to request and obtain access. A solution scope is a technique that helps to define the boundaries and context of the solution. A solution scope identifies the elements that are within the scope, the elements that are out of scope, and the interfaces and interactions between the elements. A solution scope can help the BA to clarify the objectives and requirements of the solution, but it does not identify the stakeholder who can approve access to the database. A requirements architecture is a technique that helps to organize and structure the requirements into a coherent and consistent framework. A requirements architecture defines the relationships, dependencies, and hierarchies among the requirements, and the level of detail and abstraction of each requirement. A requirements architecture can help the BA to manage the complexity and traceability of the requirements, but it does not identify the stakeholder who can approve access to the database. A change strategy is a technique that helps to plan and manage the changes to the requirements or the solution throughout the project lifecycle. A change strategy defines the roles and responsibilities, the criteria and procedures, the tools and techniques, and the documentation and communication for handling the changes. A change strategy can help the BA to ensure that the changes are properly identified, analyzed, approved, implemented, verified, and tracked, but it does not identify the stakeholder who can approve access to the database. References: BABOK Guide v3, Chapter 10: Techniques, Section 10.14: Governance Approach, p. 516-517; Section 10.42: Scope Modeling, p. 554-556; Section 10.41: Requirements Architecture, p. 553-554; Section 10.11: Change Control Process, p. 510-512.
