If stakeholders are not identified, the business analyst may miss uncovering critical needs.
Stakeholder needs uncovered late will often require a revision to business analysis tasks that are either in progress or are completed. This can result in increased costs and decreased stakeholder satisfaction.

In the context of Business Analysis, requirements should be initially prioritized based on the business benefits they are expected to deliver. This approach aligns with the principle of delivering the most value to the organization and ensuring that the most impactful requirements are addressed first. Prioritizing by business benefits helps in focusing on what is most important for achieving business objectives and delivering value to stakeholders.
References: The prioritization of requirements is a critical step in the requirements life cycle management, as outlined in the BABOK Guide. While the guide itself is not publicly accessible without membership, it is widely recognized that business benefits are a key factor in prioritization. This is supported by various resources and articles that discuss prioritization methods within the domain of Business Analysis.

A solution is considered successful when it satisfies the business need it was intended to address. This means that the solution has effectively resolved the problem or fulfilled the requirement that prompted its development. While meeting stakeholders' expectations, ensuring the organization is ready to accept the solution, and having a positive performance evaluation are all important, they are secondary to the primary goal of meeting the business need.
References: The Business Analysis Body of Knowledge (BABOK) guide emphasizes that the success of a solution is measured by its ability to meet the business needs. This aligns with the principles and practices outlined in the resources provided by the International Institute of Business Analysis (IIBA) for business analysis certifications1.

Decision Modelling and Estimation are techniques that can be applied to prioritize requirements effectively.
Decision modelling helps in understanding the implications of various choices and selecting the best course of action based on the analysis. Estimation provides insights into the effort and resources required to fulfill the requirements, which is crucial for prioritization, especially when resources are limited or when there are time constraints.
References: The BABOK Guide mentions several techniques for prioritizing requirements, including Decision Analysis and Estimation. These techniques help assess the value, urgency, dependencies, and risks associated with requirements to ensure that the most important ones are addressed first1. Additionally, other sources confirm the use of these techniques in prioritizing requirements within Business Analysis23456.
