· Spiral Model

Conception:- SDLC starts with the conception phase.This phase is triggered by a competitor ,a problem or an opportunity
The problem perceived
The goal to be achieved
The benefits from the solution
The scope of the project
Initiation:- The Software engineers work with users to carry out a macro level study of the users requirements.The software engineers define the various alternatives possible and the cost-benefit
justification of these alternatives.
Analysis :- The software Engineers carry our a detailed study of the users requirement .They then arrive at the proposed system to be built .The model of this system is to be used to freeze all
requirements before the next phase begins.
Design :- In this phase the functional specifications are used for translating the model into a design of the desired system like data flow diagrams ,decisions tables,databases etc.
Construction:- This phases produces the actual code that will be delivered to the customer as the running system .Individual modules developed in this phase are tested before being delivered to the next
phase
Testing :- All the modules that have been developed before are integrated or put together in this phase, and tested as a complete system. A system is tested for online response ,volume of
transactions, stress, recovery from failure, and usability.
Implementation:- Implementation means converting a new system design into operation .This involves creating computer compatible files, training the operating staff, installing hardware and any other
requirements.
Prototyping Process :-
