Big bang adoption or direct changeover is when a new system is adopted instantly, with no transition period between the old and new systems. [ 1 ] [ 2 ] [ 3 ] When a new system needs to be implemented in an organization , there are three different ways to adopt this new system: the big bang adoption, phased adoption and parallel adoption .
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

The main strategies are big bang adoption, parallel adoption and phased adoption. "Big bang" is a metaphor for the cosmological theory of the same name, in which the start of the cosmos happened at one moment in time. This is also the case with the big bang adoption approach, in which the new system is supposed to be adopted wholesale on one date.
In big-bang testing, most of the developed modules are coupled together to form a complete software system or major part of the system and then used for integration testing. This method is very effective for saving time in the integration testing process [citation needed]. However, if the test cases and their results are not recorded properly ...
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The notion of an expanding universe was first scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations.
Parallel adoption is a method for transferring between a previous system to a target (IT) system in an organization.In order to reduce risk, the old and new system run simultaneously for some period of time after which, if the criteria for the new system are met, the old system is disabled.

Phased implementation. Phased adoption or phased implementation is a strategy of implementing an innovation (i.e., information systems, new technologies, processes, etc.) in an organization in a phased way, so that different parts of the organization are implemented in different subsequent time slots.
