SDLC Models
WATERFALL MODEL :-
- This was widely accepted SDLC model
- In this the development of software is divided into various phases.
- The outcome of one phase is acted as input for another phase .
- It is a documentation intensive model
INCREMENTAL MODEL :-
- In this the series of waterfall model were there.
- The req. were divided into group at the start of project.
- For each group the sdlc model was followed to a development software
- The SDLC process was seperated with each release adding more functionality
until all requirements were met. - Modifications to incrimental model allowed the development cycle to overlap
with the preveious one - Subsequent cycle they had to begun before the previous cycle was actually complete.
AGILE MODEL
- In this model the entire project was divded into small incrimental builds abd,
- The development team and the testing team was in continious inetraction with
each other that led to be a good development model.
SPIRAL MODEL
- This was initially and now a RISK driven model
- this helps team to adapts models from one or more process models.
- This adopts the best features of the prototyping in Concurrency,design and development activities.
Agile model was not that much continious which led to the development of DevOps.
