An Overview of Big Bang Model in Software Development

Introduction to Big Bang Model in Software Development

The Big Bang Model of software development is a high-risk model, often opted for when the stakeholders have a ‘go with the flow’, and ‘we will cross the bridge when we come to it’ attitude. This blog post is designed to give you an overview of the Big Bang model in software development, its advantages, disadvantages, and the appropriate occasions for using it.

What is the Big Bang Model?

The Big Bang Model is a software development approach that requires little planning, ample freedom, and a high level of spontaneity. In this model, more emphasis is placed on development rather than planning or design. It’s like assembling a jigsaw puzzle with a general sense of the big picture, but not enough details about where each piece goes.

Main Elements of the Big Bang Model

The Big Bang model revolves around a few main elements that distinguish it from other software development models. Here they are:

  • Minimal planning: Unlike other development methodologies which invest heavily in planning, this model isn’t burdened by heavy planning or scheduling constraints.
  • Code and develop: The primary focus in this model is the development part, it moves rapidly to coding with little emphasis on requirements or initial design.
  • Flexible for change: Changes can readily be implemented at any stage of the development process.
  • High risk: Although it allows for significant flexibility, the Big Bang model presents a high level of risk due to the lack of structure and planning.

When to Use the Big Bang Model?

The Big Bang Model should ideally be used for small projects where the project requirements are not well-defined. It could also be preferred when the client gives developers all the freedom to make software design and development decisions. However, it’s a risky choice for complex, large projects where detailed planning and precise risk analysis are crucial.

Advantages and Disadvantages of Big Bang Model

Like any other approach, the Big Bang Model has its pros and cons:


  • It’s simple and easy to manage as there is no strict process to be followed and it requires minimal resources.
  • It’s very flexible and allows for changes at any stage of development.
  • It doesn’t require a clear set of detailed requirements, affording developers significant latitude for making decisions.


  • There is a high risk factor associated due to the lack of planning and unclear requirements.
  • Testing may be overlooked until late in the development cycle.
  • Issues may arise late in the development cycle that could have been caught earlier with proper planning.

In conclusion, the Big Bang Model is a unique approach to handle specific types of software development projects. However, it’s critical to be cognizant of its inherent risk factors. A big takeaway from the model is: it’s not ‘one-size-fits-all’ for project management here – understanding the nature of your project is key!
