User accounts are formally managed from creation to deletion across all systems
A documented identity lifecycle gives access control something stable to act on: without a clear rule for how accounts are created and changed, A.5.15's access decisions have no reliable account to attach to.
Sekit's Identity lifecycle control documents how accounts are requested, created, modified and removed across company systems, the written commitment behind A.5.16; the technical enforcement and joiner-mover-leaver procedure that carry it out day to day are mapped separately here.
