Operational Automation

Routine handoffs between three applications, previously carried by email and re-keying, now run as one validated workflow with rules for routing, idempotent writes, and every exception sent to a named owner.

01

Operational Context

An operations team runs its day across three applications: one where work arrives, one where it is fulfilled, and one where it is billed and reported. None of the three was built to talk to the others, and the team sits in the gaps between them.

The work is routine in shape and varied in detail. Most items follow the same path; a minority do not, and those are the ones that matter to customers.

02

Problem

Routine handoffs between the three applications were carried by email and re-keying. A record created in one system was retyped into the next, sometimes hours later, sometimes with a field missing. Exceptions had no owner until a customer complained.

03

Business Consequence

Experienced staff spent their day copying data between screens. Errors were discovered by the customer rather than the team. Nobody could say, for a given item, where it was or who was responsible for it.

COST
Operations hours on re-keying; rework after errors
RISK
Exceptions found by customers; items lost between systems
EVIDENCE
No record of a handoff beyond the email that carried it
04

Constraints

The three applications stay. The workflow had to fit around them and around the people who run it.

APPLICATIONS
No replacement of any system. Integration through each application’s own API and permissions.
AUTHORITY
Rules move routine items. Anything that fails a rule goes to a named person, never to a default.
SAFETY
Every write is idempotent and logged. A retry can never create a duplicate.
ADOPTION
Exceptions arrive where the team already works, with the item and the reason it stopped.
CONFIDENTIALITY
Client identity, sector and figures are withheld at their request.
05

Previous System

Email threads, a shared spreadsheet used as a tracker, and three browser tabs. The email was the handoff, the spreadsheet was the memory, and the person who knew the exceptions was the system.

System Design & Architecture

The system is one path: trigger, validate, apply the rules, act, record. There is no AI component; the work is deterministic and the value is in the validation, the rules and the ledger.

Exceptions are the design, not the edge case. A named owner for each exception type was agreed before a line of code, and the workflow’s job on an unusual item is to stop it and hand it to that person with everything they need.

Architecture: APPLICATIONS · SOURCE, WORKFLOW · RULES, PEOPLE · EXCEPTIONS. Sequence: TRIGGER (Event in application A; WEBHOOK · POLL), then VALIDATE (Schema, required fields, duplicates; REJECT WITH REASON), then RULES (Mapping and routing; VERSIONED · TESTED), then ACTION (Write to applications B and C; API · IDEMPOTENT · LOGGED), then OWNER (Named owner resolves; EXCEPTION · WITH REASON), reached over an async, buffered link, a human approval gate, then LEDGER (Handoff ledger; EVERY STEP · EVERY OUTCOME), then REVIEW (Weekly exception review; OPERATIONS LEAD · RULE CHANGES).

Human Responsibility

The operations lead owns the system. Rules are changed by people and tested before release, every exception has a named owner, and the workflow can be paused with the ledger as the fallback.

09

Engineering

An event in the first application triggers the workflow. The item is validated against a schema and the required fields, checked for duplicates, then passed through a versioned rules set that maps and routes it. Writes to the second and third applications go through their APIs with idempotency keys and are recorded in a handoff ledger. An item that fails validation or matches no rule is routed to its named owner with the reason, and the ledger shows every item’s state at any time.

ASSESS
Handoffs mapped with the team, exception types catalogued, owners named, baseline defined
PILOT
One handoff path end to end, run beside the manual process until the two agreed
ENGINEER
Remaining paths, rules under test, ledger, exception routing, weekly review
OPERATE
Running with the client’s team; rules changed on request and re-tested
10

Reliability

Designed so that a failure stops an item, not the operation.

IDEMPOTENT
Every write carries a key; a retry after a timeout cannot duplicate a record
RETRY
Transient API failures retry with backoff; persistent ones become an exception with the error attached
VALIDATION
Items are rejected at intake with the reason, before anything is written downstream
LEDGER
Every step and outcome recorded; any item can be traced end to end
FALLBACK
If the workflow is paused, items queue and the team can work them by hand from the ledger
11

Measurement

A baseline was agreed with the client before the pilot and results have been measured against it. At the client’s request the figures are not published; the measures are.

PRIMARY
Operations hours on handoffs per week
SECONDARY
Time from arrival to completed handoff; exceptions found by the team before the customer
QUALITY
Items with a complete ledger trail; duplicate records created
BASELINE
The team’s own tracker and email volume for the period before the pilot
12

Results

Results were measured against the baseline agreed before the pilot. At the client’s request the figures are withheld; what can be said is what the system guarantees by construction.

  • PRIMARY OUTCOME
    Measured, withheld
    Operations hours on handoffs, against the agreed baseline. Figures held at the client’s request.
  • BY CONSTRUCTION
    Every exception has an owner
    An item that fails a rule reaches a named person with the reason, not an inbox.
  • BY CONSTRUCTION
    Every handoff has a record
    Any item can be traced from arrival to completion in the ledger.
Stacx24 does not publish percentages or ROI figures that have not been measured against an agreed baseline, or that a client has asked to keep private.

Current Status

CONFIDENTIAL CLIENTSTATUS AS OF NOV 2026

Operating with the client’s team. Rules are revised on request and re-tested before release; the weekly exception review is the mechanism for change. Client identity and figures remain withheld.

PRODUCTION
Running in the client’s operation, measured, supported.
PILOT
One bounded system, live, with a baseline and an agreed measurement period.
EARLY DEPLOYMENT
In use, still being hardened; measurement period not yet complete.
TECHNICAL DEMONSTRATION
Built to prove an approach. Not operating a real workload.
CONFIDENTIAL CLIENT
Operating; client and figures withheld at their request.
