ISO 9001 2015 Documentation Requirements

If there’s one part of ISO 9001 that confuses even experienced teams, it’s the documentation. What exactly is required? What’s just nice to have? And how do you avoid drowning in paperwork while still staying audit-ready?

I’ve spent over 10 years helping businesses—from small food producers to large industrial manufacturers—build documentation systems that actually work. Not just to get certified, but to run more smoothly day to day. And I’ve seen the same issues over and over: bloated manuals nobody reads, missing records that create last-minute panic, and documents that exist only for the auditor—not the people who actually need them.

This guide is here to clear all that up.

You’ll get a straight answer on what ISO 9001:2015 really requires, what’s optional but useful, and how to build a lean documentation system that supports your team and satisfies your auditor. Along the way, I’ll also share practical examples and tips I’ve picked up from real-world ISO projects.

Let’s get into it.

What ISO 9001:2015 Actually Requires

Let’s clear up a common misconception right away: ISO 9001:2015 doesn’t come with a giant list of documents you have to create. Instead, it talks about “documented information”—and that term trips up a lot of people.

So what does “documented information” really mean?

It’s a flexible term that covers both:

• Documents: things that guide how something should be done (like procedures, policies, or manuals).

• Records: proof that something was done (like completed checklists, meeting notes, calibration reports, etc.).

The standard doesn’t dictate how many documents you need—it tells you what needs to be clear, consistent, and controlled. That’s where your documentation comes in.

What’s Mandatory?

ISO 9001:2015 is surprisingly lean when it comes to documentation requirements. But there are specific clauses that require either a document or a record. Here’s what’s explicitly required:

I once worked with a manufacturer who had 80+ SOPs—but missed documenting their QMS scope. They passed the audit after fixing it, but it was a close call. Sometimes the simple things get overlooked.

Keep in Mind

• Design & development (Clause 8.3) only applies if your organization designs its own products or services.

• You don’t need a Quality Manual or mandatory procedures like in the 2008 version—but many companies still choose to use them (we’ll cover that shortly).

This list isn’t about adding bureaucracy. It’s about creating just enough structure to prove that your system works—and that you’re in control of it.

Mandatory ISO 9001 Documents & Records

If you’re short on time or building your QMS from scratch, this is the list you don’t want to skip. These are the non-negotiables—the documents and records that ISO 9001:2015 explicitly requires.

In my experience, teams that start with this list and build only what they actually use have the most sustainable, audit-proof systems. Everything else can be layered in strategically.

Documents You Must Have (Typically Maintained & Updated)

These define how your QMS operates. They need to be controlled (Clause 7.5), meaning current versions are reviewed, accessible, and protected from unintended changes.

Records You Must Keep (Proof of Performance)

These show evidence that you’ve followed your processes and met requirements. They don’t need to be pretty—but they must be complete, accessible, and traceable.

Don’t let records pile up just before the audit. Build daily or weekly habits for saving them in a shared folder, with dates and clear file names. Your future self will thank you.

Controlled Documents – Foundation of an Audit-Ready System

Here’s the deal: it’s not enough to have documents. You need to control them.

I’ve audited systems where companies had beautifully written procedures… but nobody knew where the latest version was. Or worse—multiple versions were floating around in inboxes. That’s a fast track to nonconformities, confusion, and frustrated teams.

Clause 7.5 of ISO 9001:2015 makes it clear: documented information must be controlled so that it’s available, accurate, and current.

So, what makes a document “controlled”?

It comes down to a few key things:

1. Version control
   → Every document should have a version number, issue date, and ideally a change history.

2. Access control
   → Who can view it? Who can edit it? Not everyone needs to be able to make changes.

3. Approval before release
   → Documents should be reviewed and approved before they’re shared or used.

4. Change management
   → Any updates must be recorded—and obsolete versions must be removed from circulation.

5. Availability where it matters
   → A procedure isn’t useful if it’s buried in an admin folder no one checks. It needs to be where the work happens.

In one client audit, we avoided a major finding by showing how controlled versions were stored in Google Drive with restricted access and audit trails. No fancy QMS software—just a clear process.

Real-World Example

At a small food processing plant I supported last year, we had a common issue: operators were printing uncontrolled copies of SOPs to post near equipment—and then making notes on them. That led to errors and undocumented changes.

The solution? We created read-only PDFs for posting and trained team leads to collect feedback on changes through a documented review process. Everyone knew which version was current—and the auditor loved the traceability.

Best Practice

Create a Document Control Procedure that outlines:

• Document creation and review workflows

• Naming conventions and formatting rules

• How obsolete versions are archived

• How external documents (like supplier manuals or standards) are handled

Even if ISO 9001 doesn’t require a formal procedure for everything anymore, this one is worth having.

Quality Manual: Optional But Strategic

One of the biggest shifts in ISO 9001:2015 is that a Quality Manual is no longer mandatory.

But here’s what I tell my clients: just because it’s optional doesn’t mean it’s useless.

If you’re running a business where clarity, onboarding, or multi-site coordination matters, a well-written quality manual can be one of your most powerful tools.

Why Create One?

A quality manual helps you:

• Tell your QMS story in one place—great for clients, auditors, and new hires.

• Align your team on the core processes, policies, and interactions.

• Speed up onboarding by giving a top-down view of how the system works.

• Build credibility with customers who ask, “How do you manage quality?”

In my experience, companies that build a concise, visual, and practical manual find it easier to train staff and explain their system during audits. It’s a simple way to show you understand your own system—not just follow checklists.

What to Include in a Modern, Lean Quality Manual

Skip the fluff. Focus on these essentials:

Real Client Snapshot

I worked with a consulting firm that didn’t need a manual—but their team kept asking the same questions:
“Where do I find the audit plan?”
“Who approves this form?”
“Where’s the process flow?”

We built a 6-page manual with a simple diagram and hyperlinks to core documents. Result?

• Onboarding time dropped by 40%.

• Internal audits ran smoother.

• Everyone finally understood how their work fit into the QMS.

Beyond the Bare Minimum – Smart Documentation That Serves Operations

Getting certified with just the minimum documentation is possible. But in practice? That kind of system usually falls apart after the audit. Why? Because it’s built to impress auditors, not to support the actual people doing the work.

In my experience, the best ISO 9001 systems go beyond the checklist. They use documentation as a strategic tool—not a compliance burden.

What “Smart” Documentation Looks Like

Here’s the rule I always share with clients:

If the process is critical or prone to error—document it.

Smart documentation isn’t about volume. It’s about targeted clarity. That includes:

Procedures for high-risk processes

Think purchasing, nonconformity handling, or product release. If errors here could affect customer satisfaction or product safety, you need a clear, repeatable method.

Work instructions for complex tasks

These are your step-by-step guides—especially helpful in operations, maintenance, packaging, or technical processes.

Checklists and forms

Not just for the auditor. These help your team stay consistent, prove completion, and reduce “forgetfulness” errors. Think inspection logs, cleaning records, and CAPA reports.

Real Example: A Bottling Facility with 3 Near-Misses

I worked with a food bottling facility that had a documented procedure for sanitation… but no daily checklist for verifying it. Three batches were almost released without proper cleaning verification.

We fixed that with a simple one-page form and a supervisor sign-off column. That single document reduced risk—and they passed their next audit with zero findings.

Don’t Let This Be You:

• A 20-page procedure nobody reads

• A beautiful flowchart that doesn’t match how work is actually done

• A document created 3 years ago and never reviewed

Your documentation should be living, used, and understood.

Pro Tip Box:

“Ask your team: What document would help you avoid mistakes in this process?”
Their answers are often better than anything you’d write alone.

When in doubt, document to support the person doing the task, not to please the auditor. The auditor just wants to see that what’s written matches what’s done—and that the system is consistent.

Paper or Digital? Choose the Format That Scales

Once your documentation is under control, the next question is: Where do you keep it all?

I’ve worked with companies who still print every procedure and file it in color-coded binders. I’ve also worked with teams using cloud platforms, apps, and automated workflows. Both setups can work—if they’re done right.

But here’s the truth: format matters less than usability.

The Case for Paper-Based Systems

Pros:

• Simple to implement, no software needed.

• Easy for shop floor teams with limited tech access.

• Tangible—some people still trust a physical document more.

Cons:

• Harder to manage version control.

• Prone to outdated or damaged copies.

• Not ideal for multi-site or remote access.

One client in a food factory used laminated SOPs at each station. It worked well—until we realized some had been printed 18 months ago and didn’t reflect recent process changes. The documents were “visible,” but no longer valid.

The Case for Digital Systems

Pros:

• Easier to manage access, updates, and version tracking.

• Accessible from anywhere—great for multi-location teams.

• Integration with audit trails, training logs, and approvals.

Cons:

• Needs setup: permissions, training, and structure.

• Risk of “over-digitizing” (if people can’t find the right document fast, they won’t use it).

I’ve helped teams set up document control in Google Drive with folder rules and naming conventions. No fancy QMS software—just clear structure, reviewer checklists, and access control. Auditors loved it because everything was traceable and current.

What Matters Most (Regardless of Format)

• Can your team find what they need, when they need it?

• Do you know which version is in use?

• Can you prove who approved it and when?

If the answer is “yes” to all three, you’re already ahead of most companies.

Expert Tip:

“The best system is the one your team actually uses. Choose simplicity, clarity, and accountability over flashy tools every time.”

Whether you go paper, digital, or hybrid—build a system that works for your reality, not just the auditor’s checklist.

Build a System That Works, Not Just One That Passes

At its core, ISO 9001:2015 documentation isn’t about paper—it’s about clarity, consistency, and control. When done right, it helps your team avoid mistakes, deliver quality, and stay aligned without micromanagement.

You don’t need hundreds of documents. You just need the right ones—built for your processes, not your auditor.

Over the last decade, I’ve helped organizations build lean, reliable systems that pass audits and actually support day-to-day operations. The difference always comes down to this:
Does the documentation help the team do better work—or is it just sitting in a folder?

Now that you’ve got a clear map of what’s required and what’s strategic, you’re in a position to build a documentation system that’s not just compliant—but sustainable.
