Transition Approach:
Big bang adoption or direct changeover is the adoption type of the instant changeover, when everybody associated with the old system moves to the fully functioning new system on a given date.Source: Wikipedia.org
Phased adoption is a strategy of implementing an innovation (for example, information systems, new technologies, processes, and so on) in an organization in a phased way, so that different parts of the organization are implemented in different subsequent time slots.Source: Wikipedia.org
Cloud multitenant software is sometimes called vanilla when not customized from their original form, meaning that they are used without any customizations or updates applied to them.Source: Wikipedia.org
Commercial off-the-shelf products are packaged solutions which are then adapted to satisfy the needs of the purchasing organization.Source: Wikipedia.org
Custom Software is software that is specially developed for some specific organization or other user.Source: Wikipedia.org*
