A significant question that faces all analysts is how much effort to expend studying and documenting the existing system (if one exists). Excess attention to an existing system can consume considerable time and can result in simply updating that system with newer technology. As a result, no matter how inefficient the current system is, system developers simply reimplement the procedures that are already in place. On the other hand, if a new system inherits many or all of the requirements of an existing system, then an analyst risks missing important requirements through insufficient study of the existing system. To minimize both risks, analysts must balance the review of current business functions with discovery of new system requirements. It is still critical to have a complete correct set of system requirements, but in today’s fast-paced world, there is no time or money to review all the old systems and document all the inefficient procedures. In fact, in today’s development environment, one of the most valuable capabilities that a good system developer can bring is a new perspective to the problem. How the analysts must balance the review of current business functions with discovery of new system requirements, indetails.
