End-to-end outcomes · Query to resolution

Query to resolution

A question becomes a ticket, the ticket becomes a diagnosis and the diagnosis becomes a change. Two towers touch it and one function owns all of it.

What the chain measures

Cycle time, wait and cost are computed on complete chains only. Everything else is computed on every assembled chain and says so.

The chain, stage by stage

3 stages · the wait column is the gap before that stage began, measured on the chains that reached it

The ticket and the agent run share the service desk. The change record sits in the configuration system and names no requester, so the step into it cannot be joined on the person who raised the ticket. Every stage of this chain belongs to the same function, which is itself the finding.

What the chain costs and carries

Cost is modeled from recorded touches. Value is the amount on the designated value stage only.

Reviewed by Wei Lin Tan

Measured on the 78 chains that started early enough for the whole 120 hour commitment to fall inside the extract. Chains that started later are left out, because they could not have been seen to miss. Inside that set a chain still running past the commitment counts as a miss, not as pending.

This commitment sits alongside the function level service levels the estate already publishes, not instead of them. Every function inside this chain can hold its own commitment while this one misses.

Who owns the delay

1 boundary disputes touch this service · 1 undecided

Whether an agent failure is an incident or a model problemOpen

A ticket raised because an agent did the wrong thing is triaged by service operations and diagnosed by the agent platform. When the fix is a prompt rather than a system change, the two disagree about whether it was ever an incident.

What this page is, and what it is not

This is the only outcome in the catalog that never leaves a single function, which is why it is the one that measures itself honestly and the one with the least argument about who owns the delay.

An outcome is assembled, not recorded. No source system in this estate stamps a single reference across a purchase requisition, the order raised against it and the receipt that closes it, so the chains on these pages were stitched together after the fact. Where both documents sit in the same source system the chain is keyed and the join is exact. Where it crosses a system boundary the chain is matched on the party, the market, the region and whether the timing is plausible, and it is labeled inferred with its confidence shown. Where the two sides name no party in common the only evidence left is place and timing, and the chain is labeled cohort and confidence is capped low on purpose. A cohort chain is a hypothesis about which documents belong together. Read it as one.

The ledger behind these chains is one week, 10 to 16 August 2026, which is 168 hours. A chain that had not finished when the week ended is open, not late: the week simply stopped watching it. A chain whose commitment falls after the end of the week could never have been seen to miss, so its service level reads not measurable rather than holding. Nothing on these pages should be read as a monthly or annual attainment.

Cost to serve is modeled from the touches the ledger recorded, not billed from a timesheet. Every touch is priced at 11 minutes of a person at a loaded 58 dollars an hour, and every stage carries 1.10 dollars of system cost and 0.42 dollars of inference. Handoff cost is priced separately: waiting is held at 0.90 dollars an item an hour, rework at 34 minutes, and duplicated data entry at the re-keying minutes recorded against that handoff. Change any of those six rates and every dollar on these pages moves.
