Process Validation · PPQ & lifecycle

Is your process proven to make good product, run after run — reviewed, or built?

Two ways in. Have a validation package? Get an independent read on whether the data really proves the process is in control, at the depth you choose. Need one? Send your process and product and we build the validation from scratch.

The trendA lifecycle, not a one-time test

FDA frames process validation as a lifecycle — process design, performance qualification, then continued verification for as long as the process runs. The gap that draws findings is “validated once and filed”: the process that passed its qualification runs and quietly drifts out of control — while the paperwork still says validated.

FDA — Process Validation: General Principles & Practices

What this is

Whether the process does what it has to — against the rules, and against your own data.

Process validation is the proof that a process consistently makes product meeting its quality attributes — designed on sound science, qualified at performance (PPQ), and kept in control over time. We judge the validation you hold, or build the one you’re missing, against the governing rule and the FDA lifecycle, and against what your own executed data shows — not just whether the protocol reads correctly.

Process Validation / PPQ Defensibility Review

An independent regulatory opinion on the validation you already have — does it hold up. Start at the base; add the records that take the read past the paper.

What this covers

Process validation / PPQ — performance qualification
Process design & validation strategy
PPQ protocol & statistical batch-count justification
Blend / content-uniformity validation (supplements & food)
Acceptance-criteria-to-CQA linkage
Continued / ongoing process verification (Stage 3)

What you get back

A signed written opinion you can file in your quality system, or use to fix a gap before an inspection instead of after. Each part read against the rule and against your records, with a clear conclusion and what it would take to address it. Not a template pack of blank protocols — an independent verdict on your specific process, from a firm with no lab, no software, and no batches to run. It catches the validation that reads clean on paper and fails when an investigator follows the numbers.

What a review catches

A worked validation — a co-packer running food on a process no authority ever validated.

A constructed example: a co-packer with a process plan on file, products shipping, the file marked validated. Here is what the deeper read surfaced once the scheduled process, the kill step, and the monitoring were actually opened — each catch tied to the real rule.

Specimen drawn from the Wild Coast Pressed case — a kill step and scheduled process never validated

01The acidified product runs on a process no authority ever established.

Reads asA shelf-stable acidified food with a hot-fill process plan on file.

Hiding in itNo scheduled process from a process authority, no FCE/SID filing — the process was set in-house and never validated by anyone qualified to establish it.

Why it mattersFor an acidified/low-acid food, an established scheduled process isn’t paperwork — it’s the validation. Without it, the process is, by rule, unvalidated for safety.

21 CFR 114 / 113 · scheduled process / FCE-SID

02The juice “kill step” was never validated to the required reduction.

Reads asA juice HACCP plan with a kill step controlling the pathogen hazard.

Hiding in itThe 5-log pathogen reduction was never validated — and the chosen step (UV) physically can’t penetrate an opaque juice to deliver it.

Why it mattersJuice HACCP requires a validated 5-log reduction. A kill step that was never validated — on a product it can’t even reach — proves nothing about safety.

21 CFR 120.24 / 120.25 · 5-log validation

03One generic plan stands in for product-specific validation.

Reads asA single process/HACCP plan covering the co-pack line.

Hiding in itOne generic plan applied across distinct products and processes — none validated to its own product, hazard, and worst case.

Why it mattersValidation is product- and process-specific. A generic plan validates nothing in particular; the differences between products are exactly where the hazard lives.

21 CFR 120 / 117 · process-specific validation

!Nothing shows the process stays in control.

Reads asA “validated process,” in production, file closed.

Hiding in itNo continued process verification — no ongoing monitoring or data trending to show the process stays in control after the initial runs.

Why it mattersValidation is a lifecycle, not a one-time event. Without Stage 3, “validated” is an assumption that quietly expires while the paper says current.

The executed results hold run after run+ $1,600

A protocol written correctly is not proof the process works. Send the executed batch data — the PPQ runs, or the blend-uniformity results across locations and batches — and we check whether the results hold together run after run, not just in the one batch that looked good. The gap that turns a “validated” process into a finding when someone reads the numbers.

Optional add-on — tap to add

The acceptance criteria and run-count are justified+ $2,500

A pass only means something if the bar it passed was the right bar. Add the acceptance-criteria and run-count justification and we check whether the criteria tie to the quality attributes that matter and whether the number of validation batches is risk-justified — not the arbitrary three that an investigator asks you to defend and you cannot.

Validated once is not validated forever. Add your continued or ongoing process-verification records and we check whether the process is staying in control in routine production — and whether a change in equipment, formula, batch size, or site quietly broke the validated state. The drift that passes the qualification runs and fails six months later.

Process Validation / PPQ Protocol Development

No defensible validation yet? Send your process and product and we build the validation package from scratch — one flat fee, grounded in what your process has to control, not a generic template.

What this covers

Process validation / PPQ — performance qualification
Process design & validation strategy
PPQ protocol & statistical batch-count justification
Blend / content-uniformity validation (supplements & food)
Acceptance-criteria-to-CQA linkage
Continued / ongoing process verification (Stage 3)

What you get back

The built validation package, ready to execute and file. It states what the process has to deliver, gives a risk-based PPQ or process-verification protocol, ties acceptance criteria to the quality attributes that matter, and sets a risk-justified number of validation batches and a sampling plan. It carries the continued-verification approach for after qualification — built on what your process has to control, not a generic template for a different operation. And where the process can’t meet a defensible bar as it stands, you get the honest path to fix it at the same price, never a protocol written to pass.

What you send

The specifics we build from: the product and process — the equipment and batch sizes you run; the quality attributes the product has to hit; and any existing process knowledge or validation records you already have.

What this builds

The same operation, with no defensible validation — the calls we made, and why.

Nothing to catch on a build: you send the process and the product, and the reasoning is the work. Here is the same constructed co-packer — a cold-press juice and an acidified salsa — brought to us to validate from scratch, and the call we made at each step.

You send the process, the product, and any existing records — the starting context lives on the Wild Coast Pressed case

01We build the scheduled process in — established by a qualified process authority.

We write the package so the acidified process is established by a qualified process authority with the FCE/SID basis specified — so the process is validated by someone competent to establish it, not set in-house.

21 CFR 114 / 113 · scheduled process

02We specify a kill step that can actually deliver the reduction, on the real product.

We specify a step that can deliver the 5-log reduction on the real product — matched to an opaque juice — and set the validation approach to prove it, instead of a kill step that can’t reach the pathogen.

21 CFR 120.24 / 120.25 · 5-log validation

03We justify the criteria and batch count, and design in the monitoring.

We tie acceptance criteria to the real quality attributes, risk-justify the number of validation batches, and design in continued process verification — so the validated state doesn’t quietly expire.

21 CFR 120 / 117 · continued verification

!And the honest fork, up front: if the step can’t deliver the reduction, we say so.

Where the chosen kill step can’t be validated to the required reduction on the real product, we say so and give the path — change the step or the product — instead of a protocol that validates around a step that can’t work.

Common questions

Straight answers.

We ran three validation batches and they passed. Isn’t that validated?

Three passing PPQ batches are one stage of three. Without sound process design behind them and continued process verification after, three batches is a snapshot, not a validated state — and “three” only holds if the number was risk-justified rather than picked. The question is whether the process is proven to stay in control, run after run.

Isn’t a template pack cheaper?

Much. And it hands you blank PPQ protocols and leaves the hard part — defining what the process has to deliver, the acceptance criteria, the batch-count and worst-case basis — for you to derive and defend. You’re buying the judgment a blank form can’t give you.

Do you run the validation batches or operate the line?

No. The review judges your package; the build writes it. Neither runs the batches on your floor nor operates the process — that keeps the opinion independent of anyone selling you the equipment or the hours. You execute it in-house or with whoever you choose.

What if the process can’t meet a defensible bar?

You get told that plainly, at the same fee. We don’t write a protocol that sets the bar low enough to pass. Sometimes the answer is a process change or a different approach — we lay out the path and you decide.

Is this the same as equipment qualification?

No — related but distinct. Equipment qualification proves the machine is fit; process validation proves the process makes good product on it, run after run. This is the process layer; the equipment layer is its own review.

Is this legal advice?

No — it is an independent regulatory opinion or a built work product, not legal counsel, and it creates no attorney-client relationship. If your question is whether the validation holds up against the rule and your data, that is ours.

Where to go from here.

Regulatory work product, not legal advice. A deliverable is prepared from the records you submit and is not legal counsel, not a guarantee of any regulatory or customer outcome, and forms no attorney-client relationship. It is a document review or build — not a GMP audit, not protocol execution, batch running, or the laboratory validation studies (for example a microbial challenge / 5-log validation), and not the disposition or release decision. Where the records provided can’t support a defensible result, we deliver a findings report on what’s missing instead. Wild Coast Pressed is a constructed teaching case; no real company or product is depicted.
