Answer to Question 1

Determining the system's requirements is the most important phase in the systems
development process. If the requirements are wrong, the system will be wrong. If the
requirements are determined completely and correctly, then design and implementation will be
easier and more likely to result in success. Examples of requirements are the contents and the
format of Web pages and the functions of buttons on those pages, or the structure and content of
a report, or the fields and menu choices in a data entry form. Security is another important
category of requirements. The easiest and cheapest time to alter the information system is in the
requirements phase. Changing a requirement at this stage is simply a matter of changing a
description. Changing a requirement in the implementation phase may require weeks of
reworking applications components and the database.
