Which of the following are the functional analysis and allocation tools? Each correct answer represents a complete solution. Choose all that apply.
The various functional analysis and allocation tools are as follows:
Functional hierarchy diagram: It models the hierarchy of functions that the system is in charge for
performing, the sub-functions that
are required by those functions, and any business processes that are used to invoke those sub
functions. The objective of functional
hierarchy diagram is to show all of the function requirements and their groupings in one diagram.
Functional flow block diagram (FFBD): The objective of FFBDs is to construct the system
requirements into functional terms. The FFBD
classifies the major system-level (or top-level) functions that must be performed by the system to
accomplish its mission.
Timeline analysis diagram: It presents a graphical view of whether the functions are to be
accomplished in series or in parallel.
Answer option B is incorrect. The activity diagram is not a part of the functional analysis and
allocation tools.
