Definition of Software Development Life Cycle Models

Software Development Life Cycle is a software project management process. It is useful for streamlined development in data science. It contains various models, let’s know them more.

Waterfall Model

A waterfall model is famous as a linear-sequential life cycle model because it allows us to illustrate the development process linearly. 

Iterative Model

It implements the basic functionalities of the software and enhances its performance. Also well-known for mission-critical projects.

Spiral Model

It is a hybrid model that contains both waterfall and iterative models. It mostly focuses on risk analysis. 

Big Bang Model

Big Bang is a basic model that is easy to implement. It is popular among students and newcomers due to its smooth implementation.  

Agile Model

This model is extensively useful in software engineering, as there is a close association between real-world entities. 

Rapid Application Development Model

RAD is a software developing methodology based on iterative and prototyping. Its best part is that it does not require any peculiar planning. 

Advantages of Software Development Life Cycle Models

The following are some primary advantages of SDLC models:

  • Provides a defined view of the entire system, timeline, goals, and resources 
  • Design reviews assist in ensuring the quality and reliability of the resultant product
  • Increased control over the large or complex project
  • Incudes clear and comprehensive steps
  • Easy assessment of growth and expense
  • Debugging and testing of the system can be done in small iterations which deliver errors free final product

Disadvantages of the Software Development Life Cycle Models

To know the weaknesses of SDLC models, check out the following points:

  • Increased development cost and time
  • Details of the system should be specified in advance
  • The volume of record increases with time
  • Outmoded processes
  • Testing is sometimes not suitable for the whole development teams
  • With output at every stage, the final product may be uncertain
  • Models like Big bang are not ideal for any large projects by any means
