SDLC – Big Bang Model

SDLC – Big Bang Model

This software development life cycle model typically doesn’t follow any specific processes or instructions.
Development starts with the resources and efforts available at the moment, with very little or no planning at all. As a result, the customer gets a product that may not even meet the requirements. Features are implemented on the fly.

The key idea of the Big Bang SDLC model is to assign all available resources to development of the product itself, mostly in terms of coding, without bothering about meeting the plans.

Advantages if Big Bang SDLC model:

  • Dramatically simple model
  • Almost no planning needed
  • Simple to manage

  • Flexible for the development team

Disadvantages of Big Bang SDLC model:

  • Doesn’t fit complicated, long-term, or object-oriented projects
  • High probability of wasted resources due to uncertain requirements
