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 .
The scientific model concerned with the origin of the first organisms from organic or inorganic molecules is known as abiogenesis, and the prevailing theory for explaining the early development of the universe is the Big Bang model.
The horizon problem (also known as the homogeneity problem) is a cosmological fine-tuning problem within the Big Bang model of the universe. It arises due to the difficulty in explaining the observed homogeneity of causally disconnected regions of space in the absence of a mechanism that sets the same initial conditions everywhere.
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.
The V-Model reflects a project management view of software development and fits the needs of project managers, accountants and lawyers rather than software developers or users. Although it is easily understood by novices, that early understanding is useful only if the novice goes on to acquire a deeper understanding of the development process ...
V-Model (software development) - an extension of the waterfall model; Unified Process (UP) is an iterative software development methodology framework, based on Unified Modeling Language (UML). UP organizes the development of software into four phases, each consisting of one or more executable iterations of the software at that stage of ...
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.

Bang later discovers that the discomfort is a failed attempt at mind control by a demon trapped beneath the mountain at Demonhead's northern end. The demon failed to control Bang, but manages to control Bang's ally, Michael. The demon sets up a plot through Michael to entice Bang with treasure requiring the use of a Magic Stone.
