Software Feasibility 

The analyst conducts Initial study of problems

• Technical possibles ?
• Economical Possible ?
• Legally Possibles ? Etc...... 

Analysis 

BRS/ BDD/ FRS/ UCD Perform the investigation System flow chart and Data flow diagrams


BRS (Business Requirement Specification)
BDD (Business Design Document)
FRS (Functional Requirement Specification)
UCD (Use Case Document)

Design

• User interface design  
• Input screens
• System security 
• Low level design
• High level design

Coding :-

• Program devolepment 
• Equipment gathering
• Drop up user guides

Testing :-

It is process of executive with the indent of error.
