CMMC preparation isn’t just a technical checklist — it starts with conversations that shape how your organization will approach the entire process. That first scoping call sets the tone. It’s the deep dive that frames your path to CMMC level 2 compliance and clarifies everything from asset boundaries to documentation gaps.
Stakeholder Alignment on System Boundary Definitions
System boundaries define what parts of your organization fall under the CMMC level 2 requirements. This step sets the perimeter for where Controlled Unclassified Information (CUI) lives, flows, and is protected. During the scoping call, all key stakeholders — IT, security, operations, and compliance leads — come together to agree on what is in scope. It’s not just about drawing a digital line; it’s about identifying which systems interact with federal contract data and separating them from the rest of the network.
Clear boundaries also help prevent compliance overreach. Without alignment, organizations risk adding unnecessary systems into scope, which increases the cost and complexity of audits. By working with a CMMC RPO or C3PAO early in this conversation, teams can pinpoint exactly what infrastructure needs to be assessed and avoid costly misunderstandings down the line. This definition drives how the rest of the assessment is built.
Identification and Classification of CUI-Relevant Assets
After boundary discussions, the next focus is zeroing in on assets — not just devices and servers, but also databases, applications, and cloud platforms that store, transmit, or process CUI. This step often uncovers surprising connections. For example, a backup system that wasn’t considered sensitive might actually retain files containing CUI, which would place it squarely in scope under CMMC level 2 requirements.
During the scoping call, organizations walk through each function and tool used in their operations to ensure nothing is overlooked. This is where classifications matter — knowing which assets are CUI-relevant is essential for developing an effective System Security Plan (SSP) and avoiding audit issues later. It’s not just about inventorying; it’s about understanding each asset’s role in your compliance posture.
Comprehensive Review of Existing SSP and Related Documentation
The SSP isn’t just a formality — it tells the story of how your organization meets each CMMC level 2 requirement. During the scoping call, assessors or advisors will often request a preliminary review of your current SSP and associated artifacts like network diagrams, policies, procedures, and risk assessments. This isn’t about grading your homework — it’s to understand how ready your documentation is for a formal CMMC level 2 compliance assessment.
What gets flagged here is usually tied to gaps in clarity or consistency. Maybe your SSP outlines control implementation, but there’s no matching evidence in policy or actual practice. Or perhaps a policy hasn’t been updated in two years. Catching those issues early gives your team the chance to resolve them before they become audit blockers. This stage can save weeks during actual assessment prep.
Agreement on Network Segmentation Strategies for Compliance Clarity
Segmentation is more than a cybersecurity best practice — in the CMMC world, it’s a practical strategy to reduce assessment scope. During the scoping call, assessors look at how segmented your environment is between systems that handle CUI and those that don’t. A strong segmentation strategy can help isolate CUI environments, minimizing how many devices and users fall into scope.
Organizations with flat networks often face a heavier lift. That’s why scoping discussions include suggestions for network redesigns, firewall rules, or VLAN configurations that could streamline the process. A good segmentation approach not only supports compliance but also enhances security by containing threats and limiting lateral movement. This is the moment to decide whether a full overhaul or small adjustments are needed to meet CMMC compliance requirements efficiently.
Determination of Assessment Sampling and Evidence Expectations
CMMC assessments require real proof — screen captures, logs, user training records, and more. During the scoping call, the assessor or CMMC RPO will outline what types of evidence will be needed and how sampling will be done. This helps organizations prepare specific documents or technical evidence rather than scrambling later during the audit.
This is also where discussions about user roles come into play. Will assessors interview IT staff, end users, or executives? Will they request live demonstrations of technical controls? These are all decisions that emerge during this conversation. The more you understand what your C3PAO expects, the better your internal team can prepare without second-guessing or delays.

Clarifying Roles and Responsibilities for Controls Implementation
CMMC level 2 compliance isn’t just the IT department’s job. During the scoping call, there’s often a necessary discussion around who owns what — from policies to technical controls to user awareness training. Each requirement must have a responsible party, and ambiguity here can cause confusion or duplication of effort later.
Many organizations realize during this step that roles haven’t been formally assigned. A patching policy, for example, might be written by one team but executed inconsistently by another. These role clarifications help solidify internal accountability and ensure that implementation happens the way it’s written in the SSP. It’s about operational alignment, not just documentation.
Finalizing Timelines and Deliverables to Meet CMMC Level 2 Milestones
Timelines come into focus at the end of the call. With all requirements scoped, documentation reviewed, and asset boundaries set, it’s time to align on a realistic project schedule. This includes preparation time, expected duration of gap remediation, document updates, and potential C3PAO availability for formal assessment.
Deliverables — like an updated SSP, POA&M, and control implementation evidence — are also reviewed. If working with a CMMC RPO, milestones might include internal audits or tabletop exercises. This part of the conversation is about creating momentum. Without clear goals and dates, teams often lose time. A focused timeline keeps compliance efforts on track and measurable, leading to a smoother certification process.
