Bigbang model in software engineering tutorial and example. While the tenets of the big bang model, such as they are, are almost excessively simple, use of the model should not be wholly discarded or ignored, as it can be a powerful tool to manage the software development life cycle of a wide range of projects. This model has no certain techniques to work on a software development. The major disadvantage is that in general it is very time consuming. Modern software execution is a multifaceted mission. In big bang model the product development process just starts with the required money and efforts as the input, and the output is the software developed product which not gives the guaranty to the customer. Here, the term mass refers to the inverse of the fitness function value.
