Reveal correct answer
Correct answer: D
A.
Systems may be reactivated, repurposed, or undergo refurbishment to extend their operational life or address changing requirements. Systems can transition between different life cycle stages based on organizational needs and strategic decisions. See INCOSE SE Handbook 5th Ed., section 2.1.1., pp.25 and 26.
B.
System life cycle stages can occur concurrently and the most commonly observed situation is the parallelism between utilization and support stages. See INCOSE SE Handbook 5th Ed., section 2.1.1., pp.25 and 26.
C.
System life cycle stages can be re-entered multiple times, as it happens when an evolutionary life cycle approach with multiple development and utilization stages is adopted. See INCOSE SE Handbook 5th Ed., section 2.1.1., pp.25 and 26. See also section 2.2., p.33.
D.
To enter into the retirement stage, the SOI (in this case, a SoS) doesn't have to be entirely retired. See INCOSE SE Handbook 5th Ed., section 2.1.1., pp.25 and 26.
