Software Development Methodologies

A software development methodology or system development methodology in software engineering is a framework that is used to structure, plan, and control the process of developing an information system. 

Broadly these are:

1. Software development life cycle methodology
2. Agile methodology 

There are many models under these methodologies

1. Software development life cycle:
   
   • Waterfall: a linear framework 
   • Spiral: a combined linear-iterative framework 
   • Incremental: a combined linear-iterative framework or V Model 
   • Prototyping: an iterative framework 
   • Rapid application development (RAD): an iterative framework
2. Agile methodology:
   • Scrum 
   • Extreme programming
   • Adaptive software development (ASD) 
   • Dynamic system development method (DSDM)
