 The predictive approach provides the appropriate level of formality for this project. The predictive approach is a method of planning and managing projects that follows a predefined and sequential process. The predictive approach aims to define the scope, requirements, and deliverables of the project upfront and minimize changes during the implementation. The predictive approach is suitable for projects that have a clear and stable vision, well-understood requirements, and low uncertainty or risk.

The other options are incorrect because:

Option B is incorrect because the reactive approach does not provide the appropriate level of formality for this project. The reactive approach is a method of planning and managing projects that responds to changes and issues as they arise. The reactive approach does not follow a predefined or sequential process, but adapts to the changing needs and expectations of the stakeholders. The reactive approach is suitable for projects that have a vague or evolving vision, unclear or changing requirements, and high uncertainty or risk.

Option C is incorrect because the proactive approach does not provide the appropriate level of formality for this project. The proactive approach is a method of planning and managing projects that anticipates and prevents potential problems or opportunities before they occur. The proactive approach involves identifying, analyzing, and mitigating risks, as well as enhancing benefits and value. The proactive approach is suitable for projects that have a complex or dynamic environment, multiple or conflicting stakeholder interests, and significant impacts or dependencies.

Option D is incorrect because the adaptive approach does not provide the appropriate level of formality for this project. The adaptive approach is a method of planning and managing projects that delivers the solution in increments or iterations. The adaptive approach involves frequent feedback, collaboration, and testing to ensure that the solution meets the stakeholder needs and expectations. The adaptive approach is suitable for projects that have an emergent or innovative vision, flexible or variable requirements, and moderate uncertainty or risk.

CCBA Exam Questions, question 21

Sample size is the number of observations or data points that are used to measure the performance of a solution. Sample size is an important consideration for the BA to obtain reliable and valid information, as it affects the accuracy, precision, and confidence of the results. A larger sample size can reduce the sampling error and increase the representativeness of the population, but it may also increase the cost and time of data collection. A smaller sample size can save resources and time, but it may also introduce bias and uncertainty in the results. Therefore, the BA should determine the appropriate sample size based on the purpose, scope, and quality criteria of the performance measurement12. The other options are not directly related to the data collection process, although they may influence the analysis and interpretation of the data. References:

 The business analyst will use the solution scope as a guideline to define the relationships between business requirements and solution components. The solution scope describes the boundaries of the solution, including what is in scope and what is out of scope, as well as the key assumptions and constraints that affect the solution1. By using the solution scope, the BA can ensure that the requirements and the solution components are aligned with the business needs and the stakeholder expectations, and that they do not conflict with each other or introduce unnecessary complexity or risk.

References: The answer is based on the BABOK® Guide, which is a key resource for the CCBA® certification. Specifically, it relates to the Strategy Analysis knowledge area, where defining solution scope and business case is a key task for the BA12. It also relates to the Requirements Analysis and Design Definition knowledge area, where the BA should specify and model requirements and designs, and allocate requirements to solution components

 According to the BABOK® Guide, risk attitude is the degree to which an organization or stakeholder is willing to accept or avoid risk. There are four types of risk attitudes: risk neutral, risk averse, risk tolerant, and risk seeking. A risk neutral attitude means that the organization or stakeholder is indifferent to risk and makes decisions based on the expected value of the outcomes. A risk averse attitude means that the organization or stakeholder prefers to avoid risk and is willing to accept a lower return or pay a premium to reduce the uncertainty. A risk tolerant attitude means that the organization or stakeholder is willing to accept risk and is not concerned about the variability of the outcomes. A risk seeking attitude means that the organization or stakeholder prefers to take risk and is attracted by the possibility of higher returns or rewards. In this scenario, the corporation’s attitude towards risk is risk averse, as it decided to cancel the initiatives that were driven by the government regulations based on the prediction of an industry thought leader. This shows that the corporation prefers to avoid the risk of investing in projects that may become obsolete or non-compliant due to the regulatory changes, and is willing to forego the potential benefits of those projects. References:
