The SDLC Big Bang model in software engineering is mainly used for temporary purposes and small types of projects. This model is the easiest model in software engineering.
Big bang model sdlc needs minimum planning for the development. However, it needs more extra development and costing to develop a software product. As per the big bang’s theory, If you put some extra development and costing in the software product then you will achieve the best software product.
As this model no need to follow any process to develop software products so customers will not be sure about the final product and future needs.

Advantages And Disadvantages Of Big Bang Model
Big Bang Model Advantages
- There is not required planning.
- Useful for small projects
- It is very easy to manage
- Flexible for development team
- Less resources required.
Big Bang Model Disadvantages
- Not useful for large projects
- Risk involved
So in this way, This model use in the software development life cycle mode. This model can use if the requirements are temporary.
Frequently Asked Questions (FAQs)
1. What is the Big Bang model? The Big Bang model is a cosmological theory that suggests the universe originated from a highly compact and dense state around 13.8 billion years ago. It proposes that the universe has been expanding ever since and continues to do so.
2. What caused the Big Bang? The Big Bang theory doesn’t necessarily explain the cause of the initial singularity, the incredibly dense and hot state from which the universe expanded. The theory describes what happened shortly after the singularity, not necessarily what caused the singularity itself.
3. How was the Big Bang theory developed? The idea of an expanding universe was first suggested by Belgian astronomer Georges Lemaître in the 1920s. Edwin Hubble’s observations of galaxies moving away from each other provided observational evidence for this expansion. The term “Big Bang” was coined by British astronomer Fred Hoyle in a somewhat derogatory manner, but the name stuck.
4. What evidence supports the Big Bang theory? Several lines of evidence support the Big Bang theory:
- Cosmic Microwave Background (CMB): The discovery of the CMB radiation, a faint glow of radiation left over from the early universe, supports the idea of a hot and dense initial state.
- Redshift of Galaxies: The observed redshift in the spectra of distant galaxies suggests that the universe is expanding, which is a key prediction of the Big Bang model.
- Abundance of Light Elements: The observed abundances of light elements like hydrogen and helium match the predictions made by the theory regarding the conditions of the early universe.
- Large Scale Structure: The distribution of galaxies and galaxy clusters in the universe aligns with the predictions of the gravitational effects from the initial conditions of the Big Bang.
5. What happened right after the Big Bang? The universe underwent a rapid and exponential expansion known as cosmic inflation during the first tiny fraction of a second after the Big Bang. As the universe cooled down, particles started forming, and eventually, protons, neutrons, and electrons combined to form hydrogen and helium nuclei.
6. Is the universe still expanding? Yes, the universe is still expanding. This expansion is ongoing and is observed through the redshift of galaxies. The rate of expansion, known as the Hubble constant, is a subject of active research.
7. Does the Big Bang theory explain everything? While the Big Bang theory explains the expansion of the universe and the cosmic microwave background radiation, there are still open questions it doesn’t fully address, such as the nature of dark matter and dark energy, the initial conditions of the universe, and the unification of gravity with the other fundamental forces (quantum gravity).
