A feasibility study is a technique that involves evaluating the viability and suitability of a proposed project or solution. A feasibility study can help the business analyst to define the scope of this project by assessing the technical, economic, legal, operational, and schedule aspects of designing and building three bridges within a limited time frame. A feasibility study can also help to identify the risks, benefits, costs, and assumptions associated with each bridge project.

Requirements are statements of the needs, expectations, or conditions that must be met by a solution.
Requirements should be clear, complete, consistent, and testable, so that they can be understood, verified, and validated by the stakeholders. If the requirements are not ready for peer review, it means that they have not met these quality criteria, and that they need to be refined or revised. One possible cause of this situation is that the requirements do not provide all of the information needed to define the work, such as the scope, objectives, deliverables, assumptions, constraints, risks, dependencies, etc. This would make it difficult for the peer reviewers to evaluate the feasibility, accuracy, and alignment of the requirements with the business needs and goals. The other options are not likely to cause this problem. Some requirements having not yet been discussed in a work group session is not a reason to delay the peer review, as long as the requirements have been elicited from the relevant sources and documented properly. The requirements' reference codes not tracing to the attribute numbers in the work breakdown structure is a minor issue that can be easily fixed by updating the reference codes or the work breakdown structure. The requirements documents having not yet received sign-off from the sponsor is not a prerequisite for peer review, as sign-off is usually obtained after the peer review and validation process.

Engaging all stakeholders early in the requirements gathering phase is a good practice to ensure stakeholder satisfaction with the enhancement. By involving the stakeholders in the elicitation process, the business analyst can understand their needs, expectations, preferences, and constraints. By defining the acceptance criteria with the stakeholders, the business analyst can establish a clear and measurable definition of what constitutes a successful solution. Engaging all stakeholders early can also help to build trust, collaboration, and buy-in for the change. Requesting that the project manager identify all affected project stakeholders is not sufficient to ensure stakeholder satisfaction, as it does not involve direct communication with the stakeholders. Providing all signed-off project documentation to the stakeholders for information purposes only is not effective, as it does not allow for feedback or validation from the stakeholders. Soliciting feedback and adding requirements to the project backlog is not advisable, as it can lead to scope creep, rework, and delays.
