Evidence-confidence model
Every statement says how we know it
A process map is only as trustworthy as the evidence behind each box. Each inventory statement carries one of seven classifications, so reviewers can see at a glance what is proven, what is believed and what is still disputed.
StrongestObserved
Seen directly: a walkthrough, a system screen, a live case or an extract.
StrongDocumented
Written in a current policy, procedure, SOP or control description.
StrongOwner-confirmed
Stated or confirmed by the accountable owner of the process or control.
ModerateInferred
Reasonably deduced from related evidence, but not stated anywhere.
WeakAssumed
A working assumption the team has recorded so it can be tested later.
Needs resolutionConflicting
Two sources disagree. Both stay visible until an owner decides.
OpenUnresolved
A known gap. It is tracked as an open question, not filled with a guess.
