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.
