How for-review sign-off, chain-of-command transitions, and role-based gating turn ticket statuses from a free-text field into an operational policy engine.
The old way. Tickets have an enum: Open, In Progress, Resolved, Closed. Anyone can transition between them. The agent who opened the ticket marks it Resolved without checking with the reporter. The reporter never sees the resolution. The ticket reappears two weeks later under a different category. Compliance is unable to audit who closed what when.
What ISPCQ does. Each note category has its own state machine: which status can transition to which, who can perform each transition, what evidence is required. For-review sign-off means the reporter verifies the fix before close on every note type. Close (Error) and Reopen are first-class transitions. Chain-of-command rules let team leaders close notes raised anywhere in their reporting line without explicit assignment.
The operational outcome. Premature closures drop to near-zero. Compliance has the audit trail it needs. Reporters experience accountability rather than "the ticket disappeared."
