Question 24
[ID-5001] Two life cycle processes interact with one another a few times in a given system hierarchical level. This is called:
-
A
Recursion
-
B
Concurrency
-
C
Interaction
-
D
Iteration
Reveal correct answer
Correct answer: D
A.
Recursion happens when the same system life cycle process is applied to sucessive hierarchical levels. This happens, for example, while applying verification to single equipment and then verifying the integrated set afterwards. See INCOSE SE Handbook 5th Ed. Section 2.3.1.2, pp.42-44. See INCOSE SE Handbook 5th Ed. Section 2.3.1.2, pp.42-44.
B.
Concurrency is the parallel application of different system life cycle processes in the same hierarchical level. See INCOSE SE Handbook 5th Ed. Section 2.3.1.2, pp.42-44.
C.
Interaction is a general term that can describe any form of communication or exchange between two entities. While life cycle processes do interact with each other, the specific scenario described in the question, where two processes interact multiple times at a given system hierarchical level, is more accurately referred to as an iteration in systems engineering terminology.
D.
This happens, for example, when risks are identified (Risk Management Process) due to the elicitation of system requirement (System Requirement Definition Process) and are further mitigated due to chances in the previously elicited requirement. See INCOSE SE Handbook 5th Ed. Section 2.3.1.2, pp.42-44.
