Certification of Capability in Business Analysis Changed CCBA Questions

Data modeling is a technique that involves creating a visual representation of the data and information relevant to the solution or business domain. It shows the concepts, attributes, and relationships that define the data and how they are organized and manipulated. Data modeling helps to organize requirements by providing a common understanding of the data and its structure, quality, and usage.

According to the BABOK® Guide, a change-driven approach is an adaptive approach that responds to changing stakeholder needs and delivers business value in short iterations. A change-driven approach is suitable for situations where the solution scope is not well-defined, the requirements are volatile, and the delivery time is short1. A change-driven approach emphasizes feedback, collaboration, and experimentation over documentation, planning, and control2. References: 1: BABOK® Guide, version 3, section 2.3.2, page 202: BABOK® Guide, version 3, section 2.4.2, page 23.

To answer this question, you need to compare the total cost of ownership (TCO) of the two solutions over time. The TCO is the sum of the initial cost and the recurring cost multiplied by the number of months. You can set up an equation to find the break-even point where the TCO of the two solutions are equal:

286,000 + 2,400x = 239,000 + 2,850x

Solving for x, you get x = 64. This means that after 64 months, the TCO of the two solutions will be the same. Therefore, you need to use your in-house solution for more than 64 months to be more cost effective than the vendor’s solution.

 Product scope is the features and functions that characterize a product, service, or result1. It defines what the product or service will do and how it will meet the customer needs and expectations2. Product scope is different from project scope, which is all the work needed to deliver a product, service, or result as defined in product scope1. Requirements envisioning is a technique to collaboratively identify and define the high-level features and scope of a solution3. Requirements foundation is a term used by IIBA to describe the core concepts of business analysis, such as requirements, stakeholders, and business analysis planning and monitoring4. References:
