CMMI Consulting & Appraisal-Readiness Services

CMMI (Capability Maturity Model Integration) is an internationally recognised model for building repeatable, measurable and continually improving organisational capability across development, services, security, suppliers, safety, data, people and virtual work. The current model is CMMI V3.0 (2023), with an AI-Maturity (AIM) extension added in 2026. Organisations are appraised — not 'certified' — at Maturity Levels 1–5 for a defined organisational unit. CyberSigma provides the implementation consulting to get you there: gap assessment, process development, deployment, metrics and a formal readiness review, culminating in a benchmark appraisal led by a licensed CMMI Lead Appraiser.

What CMMI Is — and What It Isn't

CMMI standardises how work is performed so delivery becomes predictable: fewer defects, less rework, controlled change and measurable performance. It strengthens project management, engineering, service delivery, security, supplier management, workforce and data management, and measures your capability against internationally recognised practice.

It is not a software checklist, a product certification, an ISO management-system standard, or a one-time documentation exercise — and it does not replace Agile, Scrum, DevSecOps, ISO, COBIT or ITIL. It is a framework for building the capabilities those methods then implement.

• Make delivery predictable and reduce cost overruns, delays and rework.
• Improve product and service quality with measurable performance baselines.
• Integrates with Agile, DevSecOps, ISO 27001/9001/20000 and NIST — it does not replace them.
• Applies to almost any sector, not just software or defence.

The 8 CMMI V3.0 Domains

CMMI V3.0 spans eight domains you can tailor to your business objectives:

• **Development (DEV)** — engineering software, platforms, hardware and product services with fewer defects and faster time to market.
• **Services (SVC)** — managed security, SOC, cloud, consulting, audit and support: strategy, delivery, continuity and incident resolution.
• **Security (SEC)** — security governance, requirements, threat and vulnerability management integrated across delivery.
• **Suppliers (SPM)** — selection, contracting, monitoring and performance of vendors, cloud and subcontractors.
• **Safety (SAF)** — safety-critical products and services (medical, aviation, automotive, energy, industrial).
• **Data (DATA)** — data governance, architecture, lifecycle and quality for data-driven decisions.
• **People (PPL)** — workforce planning, competency, development and performance.
• **Virtual (VRT)** — remote, hybrid, offshore and distributed delivery.

Maturity Levels 1–5 (and Capability Levels)

A maturity level rates a defined organisational unit across a group of Practice Areas — moving from unpredictable execution to managed, standardised, quantitatively controlled and continually optimised performance.

**Level 1 Initial** — reactive, person-dependent delivery. **Level 2 Managed** — planned, monitored and controlled at project/service level. **Level 3 Defined** — standard organisational processes, tailored and consistently used. **Level 4 Quantitatively Managed** — performance controlled with statistical methods. **Level 5 Optimising** — continuous, data-driven improvement. Levels 4–5 are 'high maturity'.

Capability levels (0–3) rate an individual Practice Area, so you can target improvement precisely — e.g. Configuration Management at Level 3 while Data Quality is still at Level 1.

Appraisal, Not Certification

Organisations are appraised, not 'CMMI certified'. A benchmark appraisal by an authorised Lead Appraiser yields a maturity- or capability-level rating (typically valid three years), which may be published in the CMMI Published Appraisal Results System. There are four formal appraisal types: Benchmark, Sustainment, Evaluation (diagnostic) and Action Plan Reappraisal.

We help you phrase claims accurately — e.g. "our defined organisational unit was appraised at CMMI Development Maturity Level 3" — never the incorrect "we are CMMI certified."

Our CMMI Engagement Process

1. **Scope & objectives** — define business goals, domains, target level and the organisational unit to be appraised.

2. **Gap assessment** — map current processes against the applicable Practice Areas and build the roadmap.

3. **Process development** — create the process library, templates, lifecycle models, tailoring and measurement.

4. **Deployment** — train teams, pilot and roll out across representative projects; collect evidence.

5. **Institutionalisation & readiness** — management reviews, independent QA, metrics, then a mock/readiness review.

6. **Formal appraisal** — supported end-to-end with a licensed CMMI Lead Appraiser, through to the rating.

CMMI + Agile, DevSecOps and ISO

CMMI defines what capabilities must exist; Agile, Scrum and DevSecOps provide how teams deliver. Sprint planning satisfies Planning; the product backlog satisfies Requirements Management; pull-request reviews satisfy Peer Reviews; CI/CD gates satisfy Quality Assurance; DORA metrics feed Measurement; retrospectives satisfy Causal Analysis.

CMMI also integrates cleanly with ISO — CMMI-DEV with ISO 9001, CMMI-SVC with ISO/IEC 20000-1, CMMI-SEC with ISO/IEC 27001, CMMI-DATA with ISO 8000. If you already run these, you are closer to Level 3 than you think.

Is CMMI a certification?

No — organisations are appraised, not certified. A benchmark appraisal by an authorised CMMI Lead Appraiser produces a Maturity Level (1–5) or Capability Level (0–3) rating for a defined organisational unit, typically valid three years. We prepare you for that appraisal and support you through it.

Which CMMI level should we target first?

For most software and services organisations, CMMI Maturity Level 3 (Defined) is the right first target — after establishing Level 2 project discipline. It gives you standard, organisation-wide processes, governance and measurement. We confirm the right domains and level in the scoping call.

How long does CMMI implementation take?

Planning estimates: an initial gap assessment takes 3–6 weeks; Level 2 typically 4–8 months; Level 3 typically 8–15 months, depending on your size, number of projects, existing maturity and evidence readiness. We give you a roadmap after the gap assessment.

What does CMMI cost?

There is no single global price — cost depends on organisational-unit size, locations, projects, domains, target level, appraisal type and Lead Appraiser fees. We provide a fixed consulting quote after a short scoping call, and help you budget the Lead Appraiser and appraisal-team costs separately.

Does CMMI work with Agile and DevSecOps?

Yes — they are complementary. CMMI defines the capabilities that must exist; Agile, Scrum and DevSecOps are valid ways to implement them (sprints, backlogs, pull-request reviews, CI/CD gates, DORA metrics, retrospectives). We map your existing Agile practice to the Practice Areas rather than forcing heavyweight process.

Which CMMI domains apply to us?

CMMI V3.0 has eight domains — Development, Services, Security, Suppliers, Safety, Data, People and Virtual. A cybersecurity or GRC firm typically starts with Development + Services, adding Security and Suppliers. We select the domains that match your business objectives in the scoping phase.
