# Cloud Maturity Model (CMM)

## Overview

The **Cloud Maturity Model** (CMM) is a structured framework for evaluating an organization's cloud adoption readiness. Developed and described by the Open Alliance for Cloud Adoption (OACA), it provides a systematic approach for organizations of all sizes and experience levels to assess their current cloud state, identify gaps, and plan their cloud transformation journey.

## Key Definition

The OACA describes CMM as a framework that:
- Assists organizations in identifying tailored solutions for adopting cloud or hybrid IT environments
- Evaluates organizations' readiness for adopting the cloud
- Helps assess their current use of cloud services
- Sets future goals for developing a cloud migration strategy
- Conducts GAP analysis
- Identifies areas for improving cloud infrastructure based on business objectives

## The 5 Maturity Levels

| Level | Name | Description |
|-------|------|-------------|
| **Level 0** | Legacy | No cloud usage, relies solely on outdated systems |
| **Level 1** | Initial Readiness (Ad hoc) | Some cloud experience, primarily for SaaS or specific business units, no clear strategy |
| **Level 2** | Repeatable, Opportunistic | Established procedures, cloud services used extensively, but approach not fully systematic |
| **Level 3** | Systematic and Documented | Documented practices, outsourced/cloud management services, efficient operations |
| **Level 4** | Measured | Transparent governance model, cloud-native applications widely adopted across organization |
| **Level 5** | Optimized | Open, interoperable cloud environment, data-driven decisions, flexible workload placement |

## Key Components

### Business Capability Areas
- Finance (CAPEX to OPEX shift)
- Enterprise Strategy
- Organizational Structure
- Culture and Skills
- Governance and Compliance
- Business Processes
- Procurement and Commercial

### Technical Capability Areas
- IT Architecture
- Applications Modernization
- DevOps
- Security
- IaaS / PaaS / SaaS / STaaS / IPaaS
- Data and Information Services
- Network Infrastructure
- AI and IoT Integration
- APIs

### Three Core Evaluation Dimensions
1. **People** — Skills, ways of working, training programs
2. **Processes** — Workflow updates, continuous improvement
3. **Technology** — Infrastructure changes, new tech adoption

## Benefits of Implementing CMM

1. **Enhanced Strategic Planning** — Focus on high-impact areas
2. **Improved Team Communications** — Shared framework for goals
3. **Enhanced Application Performance** — Smoother cloud apps
4. **Enhanced Security and Performance** — Best practices adherence
5. **Faster Time to Market** — Efficient resource use
6. **Industry Benchmarking** — Compare against sector peers
7. **Cost-Savings** — Efficiency and automation emphasis
