Question 3

Explain the importance of the requirements analysis phase of the SDLC.

Accepted Answer

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.
