The BA should recommend to assign the feature a lower priority for future release. This means that the feature will not be included in the initial release of the solution, but it may be considered for later releases depending on the availability of resources, the feedback from the stakeholders, and the alignment with the business objectives. This approach can help to balance the value and the effort of the feature, as well as to avoid scope creep and unnecessary complexity in the initial release. The other options are not the best recommendations, as they may either ignore the needs of the stakeholders, disrupt the existing business process, or increase the risk and cost of the project. References:
