 Cost-benefits analysis is a technique used in the business case development task, not in the requirements verification task. The other options are all general techniques that can be used to verify the requirements with the stakeholders and ensure they are complete, correct, and consistent. References: BABOK® Guide, section 4.5.3, page 117; section 4.6.3, page 123.

 According to the BABOK® Guide, the purpose of managing the solution scope and requirements from a business analyst’s objective is to ensure that the requirements and designs are aligned with the business need and the agreed solution scope, and that they are understood and approved by the key stakeholders. The business analyst (BA) should obtain and maintain consensus among the key stakeholders for the overall solution scope, which defines the boundaries and deliverables of the solution. The BA should also manage the changes to the solution scope and requirements, and communicate them to the relevant stakeholders. Therefore, option C is the correct answer. The other options are not the primary purpose of managing the solution scope and requirements, but rather the outcomes or benefits of doing so. References: BABOK® Guide, page 38; Business Analysis Expert Certification, CCBA® | IIBA®, section “What Should I know to be CCBA Certified?”

According to the IIBA, a data flow diagram is a technique that shows where data comes from, which activities process the data, and if the output results are stored or utilized by another activity or external entity1. A data flow diagram consists of four basic elements2:

Data flow: A data flow is a line that represents the movement of data from one point to another. It can be labeled with the name or description of the data.

External entities: External entities are rectangles that represent the sources or destinations of data outside the system boundary. They can be people, organizations, systems, or devices that interact with the system.

Data process: A data process is a circle that represents a process that transforms data by performing some operation on it. It can be labeled with the name or description of the process.

Data store: A data store is an open-ended rectangle that represents a place where data is stored or retrieved. It can be a database, a file, a queue, or a memory.

Among these elements, the one that represents a process that transforms data by combining it with other data is concatenation. Concatenation is a type of data process that joins two or more data flows into one data flow. For example, a concatenation process can combine the first name and last name data flows into a full name data flow3. References:

A weighted scoring model is a technique that assigns weights to different criteria and rates each vendor’s performance against them. The total score for each vendor is calculated by multiplying the weight and the rating for each criterion and summing them up. The vendor with the highest score is selected as the best option. A weighted scoring model is one of the tools and techniques of the Evaluate Potential Value and Recommend Solution task, which is part of the Strategy Analysis knowledge area. A weighted scoring model is different from a scoring model, which does not assign weights to the criteria and uses a simple sum of the ratings. A vendor profile assessment scale is a tool that defines the characteristics and requirements of a vendor and assigns a score based on how well they match them. A screening system is a process that filters out vendors that do not meet the minimum requirements or standards. References: Business Analysis Expert Certification, CCBA® | IIBA®, CERTIFICATION OF CAPABILITY IN BUSINESS ANALYSIS
