To determine the estimated growth rate of potential solution options, the appropriate technique is the Internal Rate of Return (IRR). IRR represents the rate at which the net present value (NPV) of future cash flows equals zero, thus indicating the expected growth rate of the investment. It is specifically used to compare the profitability of different investments by considering the expected cash flows over time.
To avoid defects being logged during user acceptance testing, the user should have been involved in the development and sign-off of the business requirements. By including the user in the process from the beginning, their needs and concerns would have been addressed, reducing the likelihood of issues arising later on.
To address a defect revealed in a test session, the business analyst should determine if the defect is in the solution developed, in the original requirement, or in the test case. This step is crucial for identifying the root cause of the defect, which then informs the appropriate corrective action. If the defect lies in the solution, it may require a change request to amend the solution. If it originates from an error in the requirements, the requirements need revision. If the defect is due to an incorrect test case, the test case itself would need correction to ensure it accurately reflects the expectations and desired behavior of the solution.
The correct action for the business analyst to take is to follow the change control process as defined in the business analysis plan. This process ensures that any changes to requirements are properly managed and approved, considering the impact on the project. It provides a structured approach to handle the change request, notify relevant stakeholders, and make necessary updates to the project plan accordingly.
When a new set of regulations is introduced, the business analyst should first identify which parts of the project are affected. This involves checking the traceability matrix to find affected use cases. By doing so, the business analyst can understand how the new regulations impact specific requirements and functionalities, laying the groundwork for further evaluation, including project schedule adjustments and management sign-offs.
