stakeholders, analysts, and project team. Change is more apparent in regard to what is usually referred to as "requirements changes" - the product/system/software requirements. These tend to reflect the presumed ways of satisfying inadequately identified business requirements. Much of the difficulties attributed to achieving business requirements in fact reflect the common practice of devoting almost all "requirements" effort to what is actually high-level design of a product, system, or software. This stems from failing to first adequately define the business requirements the product/system/software must satisfy in order to provide value. Development practices commonly keep revising the product/system/software until they eventually "back into" a solution that seems to do what is needed, i.e., apparently addresses a business requirement. Such costly

and where there is potential conflict of interest. Complexity of a business process is a factor. This may entail specialized knowledge required to comprehend legal or regulatory requirements, internal company-wide guidelines such as branding or corporate commitments to social responsibility. Business requirements analysis is not just about capturing the "what" of a business process along with "how" to provide its context. Translation into designing and building a working system may need to be addressed. At this stage, business requirements have to acknowledge technical details and feasibility.

Prototypes are preliminary versions of the software the developer intends to implement. Because prototypes are fairly concrete, stakeholders who try out the prototype can give more meaningful feedback regarding some aspects of what the developer is creating, which is the developer's interpretation of a way to satisfy business requirements, not the business requirements. Moreover, in order to create a prototype early and quickly, the

Hence, BRD documents are complemented with a systems reference document (SRD) OR Technical Design Document (TDD) that details the design, technology performance and infrastructure expectations, including any technology requirements (non-functional) pertaining to quality of service, such as performance, maintainability, adaptability, reliability, availability, security, and scalability.

Business requirements are not limited to high-level existence, but need to be driven down to detail. Regardless of their level of detail, however, business requirements are always business deliverable

Although typically defined in conjunction with the product/system/software functionality (features and usage), non-functional requirements often actually reflect a form of business requirements which are sometimes considered constraints.

To address these challenges, early stage stakeholder buy-in is achieved through demonstration of prototypes and joint working. Stakeholder workshops are common, either as facilitated sessions or simple huddled discussions, to aid in achieving consensus, especially for sensitive business requirements

Although commonly considered a means of evaluating requirements, prototyping actually usually shifts attention from business requirements to the product, system, or software being built. Prototypes are working software, which means they are three steps (product/system/software requirements,
