In the Big-Bang Model, developers do not adopt any specific process. Development begins only with the necessary funds and efforts as input, and output is developed software that may or may not be in accordance with client requirements. The Big Bang model does not follow any process/procedure and requires little planning. Even the client is unsure of what he wants, and the requirements are applied immediately without much analysis. This model is usually followed for small projects where development teams are very small.
Big-Bang Model Design
The Big Bang model involves focusing all potential resources in software development and coding with less or no planning. The requirements are understood and enforced as they come. Any changes may be required, or the entire software may not need to be improved.
This model is ideal for small projects working closely with one or two developers and is also useful for educational or practice projects. It is an ideal model for a product where the requirements are not well understood, and the final release date is not given.
Advantages of Big-Bang Model
- This is a very simple model.
- Less planning required.
- It is easy to manage.
- Very few services are required.
Disadvantages of Big-Band Model
- This model is not good for long or ongoing projects.
- High risk.
- It can be very expensive if the requirements are misunderstood.
