SDLC Big Bang Model And Phases

History:

• The Big Bang Model is the simplest model in the Software Development Life Cycle. It requires less planning, lots of coding or programming and lots of funds.
• The model name shows Big Bang as it is inspired by the Big Bang theory.
• According to the theory, scientists say that after the Big Bang blast lots of galaxies, planets, and stars are developed gradually.
• Likewise, we combined time, effort, resources, funds and then we can achieve the best software product.

Introduction:

• Big bang is not applicable for specific processes and pre proposed sequences of steps to develop application. 
• This Big Bang Model does not follow and it has slight essential planning. 
• Clients are also not sure about what they want and the requirements are implemented without much knowledge. 
• Clients may also not have solid analysis on the requirements.The majority of resources are thrown to development

Design and Application of Big Bang:

• All the possible resources in software development are focused on the Big Bang model.
• The focus also remains on the code. It is with very little or no planning.
• As soon as requirements come, they are understood and implemented without any planning.
• Any changes required and/or addition of functionality under a developed system may or may not need to revamp the complete software.
• This model is good for minor projects. Only two or three developers are enough to work on a project using this model. 

Advantages of Big Bang:

• Big Bang is a straightforward and easy-to-manage approach.
• This model provides the developers with great freedom to act on their ideas.
• Requires no management & no resources
• Is a good learning and easy for newcomers or students
• Design & Development begins immediately
• This is a very humble model. Easy to achieve

Disadvantages of Big Bang:

• It is risky and uncertain.
• Doesn’t suit complex and long-term projects.
• Hard for long or complex projects
• projects carrying are high-risk
• If project requirements are misunderstood the disaster will occur. 
• Not good  for difficult and object-oriented projects.

Conclusion:

In this article, we especially discussed one of the SDLC Big Bang models. By which we develop a small project for learning or university level. It is not suitable for the software industry to develop a big project as a highly risky model. Nowadays, all software industries use the Agile model to develop a software product. This article also provides the pros and cons of the Big Bang model.
