SDLC -Big Bang Model

The Big Bang model does not follow any particular process and customer also not sure about his requirement. There is only little formal development process. The entire effort is spent software developing and coding. Development teams are small and hence this model is usually followed for small projects.
The development starts with the money and efforts as the input, and the output is the developed software which may / may not be as per requirement.
The Big Bang model is a very high risk model because misunderstood requirements may lead to failure.

Advantages:                                                                        
  • This model is very simple
  • Management is easier
  • No planning required
  • Flexibility to developers
  • Required only few resources

Disadvantages: 

  • It is not suitable for larger and complex projects
  • Very poor model for long and ongoing projects
  • Risk is very high and uncertainty.
