Why Most CMMC Projects Become IT Projects (And Why That’s a Problem)

When organizations begin preparing for CMMC, one assumption almost always surfaces during the first planning meeting.

“Let’s have IT handle it.”

It’s an understandable reaction. After all, CMMC includes technical requirements like multi-factor authentication, endpoint protection, vulnerability management, encryption, logging, and secure cloud environments.

Surely this is an IT project.

Not exactly.

One of the biggest misconceptions about CMMC is that it requires transforming your entire organization into a compliance program. In reality, one of the smartest ways to reduce cost, complexity, and long-term maintenance is to keep as much of the business out of scope as possible by building a properly designed enclave for Controlled Unclassified Information (CUI).

But here’s where many organizations make another mistake. They assume that because the enclave is an IT environment, IT can handle everything.

It can’t.

Even a small enclave requires business decisions. Someone has to determine who needs access to CUI, how contracts are managed, how employees are onboarded, how engineering teams will work inside the enclave, and how the organization will maintain compliance over time.

The technology may live inside IT. The decisions rarely do.

Leadership Sets the Direction

Every successful CMMC project starts with leadership.

Not because executives need to configure Microsoft Intune or review firewall logs, but because nearly every significant compliance decision requires business approval.

Should the company implement a secure enclave or expand compliance across more of the organization?

Who actually needs access to CUI? How much budget should be allocated? Who will own compliance after certification?

These aren’t technical questions. They’re business decisions.

Without leadership providing direction, projects often stall while teams wait for approvals, funding, and strategic priorities.

Human Resources Helps Manage the People

HR may play a relatively small role in CMMC, but it’s still an important one. If employees require access to the enclave, HR often supports:

• Employee onboarding
• Employee offboarding
• Security awareness training
• Background screening
• Acceptable use agreements
• Confidentiality agreements

When someone joins or leaves the organization, HR and IT work together to ensure access is granted or removed appropriately.

Compliance isn’t just about securing systems. It’s also about managing the people who use them.

Engineering Defines the Workflow

In many defense contractors, engineering is where CUI is created, modified, and shared. That doesn’t mean the entire engineering department must become part of the assessment.

Far from it.

The objective is to ensure that the engineers who actually handle CUI have secure, well-defined workflows inside the enclave.

How drawings are stored. How files are shared. Which applications are approved. How data moves between suppliers and customers.

These decisions often determine whether CUI remains contained or gradually spreads throughout the organization.

Contracts May Determine Your Entire Strategy

Before building a CMMC environment, organizations need to understand what their contracts actually require.

Does the contract include DFARS clauses? Is CMMC certification required? Will the company receive, process, or store CUI?

The answers influence almost every architectural decision that follows.

In many cases, the contracts team helps determine whether an enclave is appropriate, how large it needs to be, and who actually belongs inside it.

Without that clarity, organizations sometimes build compliance environments that are much larger—and much more expensive—than necessary.

Operations Keeps the Business Moving

A secure enclave shouldn’t make it harder to run the business.

Operations helps ensure that compliance integrates smoothly into day-to-day activities without disrupting productivity.

Will engineers need new workstations? Will project workflows change? How will collaboration occur inside the enclave? How will customers be supported?

The goal isn’t to redesign business operations. It’s to make secure workflows feel as natural as possible for the employees who actually need them.

Purchasing Shapes the Environment

Every technology purchase has the potential to affect compliance.

New software. Cloud services. Engineering applications. Remote access tools. Endpoint security products.

Purchasing doesn’t need to understand every CMMC control. But understanding the organization’s overall enclave strategy helps ensure procurement decisions support long-term compliance rather than unintentionally expanding scope.

Legal Helps Manage Business Risk

Legal departments may also play an important supporting role.

They often review:

• Customer contracts
• Non-disclosure agreements
• Vendor agreements
• Third-party service contracts
• Data protection obligations

As organizations increasingly rely on cloud providers, managed service providers, and software vendors, understanding contractual responsibilities becomes just as important as understanding technical safeguards.

IT Is Critical—But It Can’t Do Everything

None of this minimizes IT’s role.

IT is responsible for implementing and maintaining many of the technical safeguards required by CMMC.

They’re the ones deploying endpoint protection, configuring Microsoft 365, managing identity, securing devices, and monitoring the environment.

But technology alone doesn’t create compliance. Leadership establishes direction. Contracts determine requirements. Engineering defines workflows. HR manages personnel processes. Operations integrates security into the business. Legal manages contractual risk.

Each group contributes where appropriate.

The Companies That Succeed Keep Their Scope Small

One of the biggest advantages of a properly designed enclave is that it allows most of the organization to remain outside the assessment boundary.

That’s exactly what many companies should strive for.

But a smaller assessment boundary doesn’t eliminate the need for collaboration.

It simply focuses that collaboration on the people and departments that actually influence how CUI is handled.

The organizations that complete CMMC most efficiently don’t try to make every employee part of the compliance effort.

They intentionally limit where CUI resides. They carefully control who has access. They build secure workflows for the people who need them. And they recognize that even the smallest CMMC environment requires thoughtful coordination between business leaders and technical teams.

Because at its core, CMMC isn’t about making your entire company compliant. It’s about protecting Controlled Unclassified Information in a way that’s secure, practical, and sustainable.
