Transition requirements are the only category of requirements that are temporary in nature. They
define the capabilities that a solution must have to facilitate the transition from the current state to
the future state, but they are not needed once the transition is complete. These include data
conversion, training, and deployment needs.
They support the implementation but are not part of the long-term functioning solution. This
distinguishes them from business, stakeholder, and solution requirements, which are ongoing or
permanent once implemented.
BABOK® Guide v3 – Section 2.3.4: Transition Requirements:
“Transition requirements describe the capabilities that the solution must have to facilitate transition
from the current state to the future state, but that will not be needed once that transition is
complete.”
