a)Feasibility – an estimate is made of whether the identified user needs may be satisfied using current software and hardware technologies. The study considers whether the proposed system will be cost-effective from a business point of view and if it can be developed within existing budgetary constraints. The result should inform the decision of whether or not to go ahead with a more detailed analysis.
b)Requirements elicitation and analysis – this is the process of deriving the system requirements through observation of existing systems, discussions with potential users and procurers, task analysis, etc. This may involve the development of one or more system models and prototypes. These help you understand the system to be specified.
c)Requirements specification – it?s the activity of transferring the information gathered during the analysis activity into a document that defines a set of requirements.
d)Requirements validation – this activity checks the requirements for realism, consistency, and completeness. During this process, errors in the requirements document are inevitably discovered.
