Food safety & quality operating system

Know what should happen. See what did. Act on the difference.

The auditor asks · 01 / 05 · CONTROL

What is supposed to happen here?

The approved procedure, limit and owner for every check.

The auditor asks · 02 / 05 · OPERATE

Was every check done—on time?

Expected records, recorded where the work happens.

The auditor asks · 03 / 05 · DETECT

Is anything outside its limit?

A rule compares every reading with its approved limit.

The auditor asks · 04 / 05 · TRACE

Which lot is this—and where did it go?

Supplier, lot, batch and shipment, one step back and forward.

The auditor asks · 05 / 05 · ACT · PROVE

Who decided, and on what evidence?

A named person, a signed decision, a linked evidence trail.

Five questions. One system.

Every answer the auditor asked for is already linked.

One event through the operating chain

Scroll the chain. Watch one case become proof.

01 · CONTROL

Define what good work requires.

For this fictional storage check, the approved maximum is 4.0°C. That value belongs to a versioned specification—not to an AI suggestion.

Human decision: A qualified person approves the control.

02 · OPERATE

Record the work where it happens.

An operator records 5.2°C for cold storage and links the observation to lot 18A. The original reading stays in the trail.

Human decision: The observation is recorded, not interpreted as a release decision.

03 · DETECT

Make the exception visible.

5.2°C is above the illustrative 4.0°C maximum. Event QE-082 is awaiting review; this flag alone does not decide whether the product is safe.

Human decision: Human review required. No release decision recorded.

04 · INVESTIGATE

Test a cause against the facts.

Review door-opening history, equipment checks and the measurement itself. A possible cause is not accepted simply because an assistant proposed it.

Human decision: The investigator reviews the conclusion and its evidence.

05 · ACT

Give the next action an owner.

The example links a proposed hold and corrective action to QE-082. A qualified person must decide product disposition; this illustration does not release or close anything.

Human decision: Approval, disposition and closure remain human-owned.

06 · TRACE

Follow the affected product.

Lot 18A stays linked to its receipt, production batch and any shipment record. A trace link identifies context; it does not prove that a recall has been completed.

Human decision: The responsible team confirms the affected scope.

07 · ASSURE

Verify that the control holds.

Review the follow-up readings and measurement checks before considering closure. A completed task and an effective corrective action are different things.

Human decision: A verifier confirms effectiveness; unresolved gaps remain visible.

08 · PROVE

Show the full basis of the decision.

The example package brings SPEC-CS-04, TEMP-082, QE-082 and the review trail together. Its review state keeps outstanding decisions visible; no finished audit outcome is implied.

Human decision: Authorized people approve the package and any subsequent changes.

Fictional case. Each dashboard number in the product is meant to open this graph—not a summary of it.

One event, followed through the system.

Existing Zentria prototype Command Center with fictional records.
01 / 06 · PROVE · ASSURE

Command Center

Each domain shows its worst open record—not a score. Overdue CAPA, a missing CCP record, lots on hold.

02 / 06 · DETECT

Quality events

Exceptions from cold chain, inspections, suppliers and complaints share one event model and one trend.

03 / 06 · DETECT · CONTROL

Opened by a rule

The event shows its originating control: CCP-02, the approved limit, the observed value and the deterministic check that raised it.

04 / 06 · OPERATE · PROVE

Evidence, verified

Device streams, monitoring forms and photos are attached with who uploaded them, when, and a content hash.

05 / 06 · ACT

Closure waits on gates

The event cannot close while a linked CAPA is open, a hold is active or a disposition is pending.

Every record connected

HACCP control, SOP, form, hold, investigation, CAPA, lot and batch—one graph, one click away.

Who does what

Three kinds of work. Kept apart on purpose.

Rules that can be checked are checked by the system. Judgement that carries accountability stays with qualified people. AI helps in between—and the core keeps working without it.

Rule engines

Deterministic

Compare, schedule, block and propagate—exactly as the approved rule says.

  • Limit check: in or out
  • Expected record: missing or late
  • Gate: no disposition, no shipment
  • Propagation: an expired COA flags open lots
  • Due dates and escalation

Works when AI is unavailable.

AI assistance

AI prepares.

Summarizes, drafts and points to what is missing—always with its sources.

  • Draft the event summary
  • Suggest 5 Why or fishbone candidates
  • Draft a CAPA and its evidence needs
  • Flag gaps in an audit package

Never invents a reading, closes a CAPA or decides disposition.

Authorized people

People authorize.

Decisions that carry accountability are signed by a named, qualified person.

  • Hold, release and disposition
  • Root-cause acceptance
  • CAPA effectiveness and closure
  • Supplier approval, recall decisions

Form completer ≠ verifier. CAPA owner ≠ effectiveness approver.

Record integrity

History is amended, never rewritten.

A submitted record keeps its original value. A correction adds who, when and why. A signature states what it means and binds to the version it signed—change the content, and the signature does not carry over.

No release or closure is implied. This is a fictional workflow, not a food-safety instruction.

Clear boundaries

What Zentria is not.

It connects to these systems and roles. It does not replace them.

  • Not an ERP
  • Not a WMS
  • Not an MES
  • Not a LIMS
  • Not a certification body
  • Not a regulator
  • Not a customs broker
  • Not an autonomous decision-maker

A full system. An explicit status.

Know what you are evaluating.

Every capability carries one label. A later capability is still part of the system—it is just not available today.

  • CURRENT

    Labelled current in the source register; available to explore in demonstrations.

  • FOUNDATION

    Partial structure or workflow; still taking shape in development.

  • VISION

    Intended scope. Not available today and not a delivery promise.
