ANSWER

Requirements reuse is when the same written requirement is used repeatedly within a single project, across a product line, or even across an enterprise. Requirement reuse can be as simple as an analyst copy/pasting requirements from a previous project, or it can be as sophisticated as having a central repository of requirements that documents link to.

Some benefits to requirements reuse are:

Faster delivery of requirements
Consistency within a project or across products
Meaning of the requirement is likely already understood by the team
Fewer defects
Higher team productivity
Reduced rework

Some downsides to requirements reuse are:

Working correctly a requirement for the first time may be time consuming
Reusing bad requirements is not helpful
Requirement wording may not fit the tone of voice of the new document
Requirement may require modification of attributes, which may present opportunity for error
If referencing a repository, the requirement may be modified without your knowledge

Do your homework prior to the business analysis interview!

Having an idea of the type of questions you might be asked during a business analyst interview will not only give you confidence but it will also help you to formulate your thoughts and to be better prepared to answer the interview questions you might get during the interview for a business analyst position. Of course, just memorizing a list of business analyst interview questions will not make you a great business analyst but it might just help you get that next job.
