Certification of Competency in Business Analysis (CCBA)

The BA should review the functional design specification of the existing system before meeting with the business sponsor and developer. This document describes the features and functions of the system and how it meets the user requirements. The BA should familiarize themselves with the current system capabilities and limitations, and identify the scope and impact of the proposed change. This will help the BA to prepare relevant questions and elicit accurate and complete information from the stakeholders. The BA should also review the other options, but they are not as important or relevant as the functional design specification for this scenario.

The solution scope is not an input of this process. The solution scope actually uses the output of the assess capability gaps process as one of its inputs. Answer D is incorrect. The business need does serve as one of the three inputs of the assess capability gaps process.
Answer: B is incorrect. The enterprise architecture does serve as one of the three inputs of the assess capability gaps process. Answer A is incorrect. Solution performance assessment does serve as one of the three inputs of the assess capability gaps process.

The plan business analysis approach is required to select an approach that will perform business analysis.
This approach helps to find out the following: Which stakeholders need to be involved in the decision? Who will be consulted regarding and informed of the approach? What is the rationale for using it? Answer: D, A, and C are incorrect. These statements are not true regarding the plan business analysis approach.

This is the only statement that correctly defines the business analysis knowledge area of requirements analysis.

Answer: B is incorrect. This statement describes the enterprise analysis knowledge area. Answer A is incorrect. This statement is the definition of the requirements management and communication domain.
Answer: D is incorrect. This statement describes the process for the elicitation of requirements in an organization.

The monies that have already been invested in the existing solution are called sunk costs. Sunk costs are the funds that have been "sunk" into the solution and are no longer available.
A is incorrect. The opportunity cost is when there are two or more solutions to choose from, but only one can be selected.
The opportunity cost is the total amount of the opportunities that cannot be selected. B is incorrect. The cost of nonconformance describes the cost of not conforming to quality, such as lost sales, lost work, defects, and even safety considerations.
D is incorrect. It is a ratio to compare the costs of a solution to the benefits received for the costs.

Change-driven approaches to business analysis deal with rapid delivery of the business value. The business value is delivered in short iterations in return for acceptance of a higher degree of uncertainty regarding the overall delivery of the solution. The change-driven approaches are preferred while taking an exploratory approach for incremental improvement of an existing solution. Answer D is incorrect. Iterative is not a valid business analysis approach. Answer C is incorrect. The plan-driven approach defines business analysis activities. This approach is used to focus on minimizing up-front uncertainty and to ensure that the solution is fully defined before implementation begins in order to maximize control and minimize risk. It is preferred when requirements are effectively defined in advance of implementation.
Answer A is incorrect. Progressive elaboration describes the project management approach of refining requirements and project scope, not the business analysis approach.

According to the BABOK Guide, a high level of abstraction means that the requirements are described in general terms without going into specific details or implementation options 3. This can make the requirements more re-usable, as they can be applied to different contexts, situations, or solutions.
Therefore, the correct answer is C.

According to the BABOK Guide, a constraint is a restriction or limitation on possible solutions 1. Among the four options, only C describes a valid constraint that limits the design and implementation of the solution. If an organizational restructure is likely to occur in one of the business departments that will use the new system, the solution must be flexible enough to accommodate different roles and responsibilities after the change. Therefore, the BA should note this constraint and communicate it to the project team and stakeholders.

A business process model describes the sequential flow of work across defined tasks and activities through an enterprise or part of an enterprise. A system process model defines the sequential flow of control among programs or units within a computer system. A program process flow shows the sequential execution of program statements within a software program. A process model can also be used in documenting operational procedures.

Decision analysis is used to rate available methodologies against organizational needs and objectives.
Answer D is incorrect. Process modeling is used to define and document the business analysis approach.
Answer A is incorrect. Structured walkthrough is used as a means of validating a created, selected, or tailored business analysis approach. Answer B is incorrect. Progressive elaboration describes the process of providing more and more information through incremental details. It is a form of deductive reasoning to go from a very broad set of requirements to the exact details on the requirements.
