According to the PMP Exam Content Outline, a project manager should select the appropriate project approach based on the project characteristics, such as the degree of uncertainty, complexity, and stakeholder involvement. A hybrid approach combines elements of predictive and adaptive (agile, iterative, incremental) approaches to suit the specific needs and context of the project. In this case, a hybrid approach would allow the project manager to accommodate the potential changes from the new CEO, while also ensuring the delivery of the correct sales results as the final product. A hybrid approach would also enable the project manager to collaborate with the customer and the development team to refine the requirements and validate the solution throughout the project life cycle. A predictive approach would not be suitable for this project, as it assumes a high level of certainty and stability in the requirements and the environment, which is not the case here. An incremental approach would deliver the product in smaller increments, which may not meet the customer's expectation of no intermediate results. An iterative approach would repeat the same phases until the product meets the desired quality, which may not be efficient or effective for this project.
