Configuration management ensures system integrity and compliance by tracking changes, managing baselines, and maintaining detailed records throughout the product lifecycle.
Configuration management is the systematic process of handling changes to systems, infrastructure, and documentation in a controlled manner to maintain integrity, traceability, and compliance throughout a system’s lifecycle. This discipline is essential across industries such as aviation, IT, and systems engineering, where reliability, safety, and regulatory adherence are paramount.
In practice, configuration management involves identifying and documenting system components (Configuration Items or CIs), controlling changes to these items, recording their status, and verifying records through audits. It extends beyond hardware and software to include documentation, procedures, and even personnel training records. Modern organizations rely on automated tools, policies, and cross-functional processes to implement configuration management, supporting quality assurance, risk management, and regulatory compliance.
A Configuration Item (CI) is any component or asset subject to configuration management—ranging from aircraft engine assemblies and avionics modules to software, infrastructure, and technical documentation. Each CI is uniquely identified and tracked throughout its lifecycle, with attributes such as version, status, relationships, and change history recorded in a Configuration Management Database (CMDB). In aviation, managing CIs is crucial for maintaining airworthiness and regulatory compliance.
Configuration data includes all the information necessary to describe, reproduce, and manage a CI or system—such as version numbers, hardware specs, software settings, maintenance records, and compliance status. Accurate configuration data, stored in structured repositories like CMDBs, empowers organizations to track system states, analyze change impacts, support incident resolution, and ensure regulatory compliance.
A baseline is a formally approved configuration of a system or CI at a specific point in time, serving as a reference for future development, modification, or restoration. Baselines are established at key milestones, such as after certification or major upgrades, and can only be modified via controlled processes. They enable organizations to detect configuration drift, support rollbacks, and maintain traceability for audits and compliance.
A Configuration Management Database (CMDB) is a centralized repository for storing information about CIs and their relationships. It supports change management, incident resolution, asset tracking, and compliance reporting. In aviation, a CMDB might include aircraft components, onboard software, and maintenance records, allowing organizations to understand system dependencies and support regulatory inspections.
Version control refers to the practice and technology for tracking changes to digital assets (software, configurations, documentation). Systems like Git and SVN record every modification, enabling traceability, rollback, and collaboration. In aviation and IT, version control is essential for maintaining audit trails, preventing errors, and ensuring that only approved configurations are deployed.
Configuration identification is the process of selecting and uniquely defining CIs within a system or project. This includes assigning identifiers, documenting characteristics, and establishing relationships. Proper identification is foundational for downstream processes like change control and auditing, especially in regulated industries.
Change control is a structured process for proposing, evaluating, approving, and documenting changes to CIs and baselines. It involves change requests, impact assessments, review boards (like Change Advisory Boards), and post-implementation verification. Change control minimizes unauthorized changes, reduces risk, and ensures regulatory compliance.
Configuration status accounting (CSA) involves recording and reporting the status of CIs, change requests, and baselines throughout their lifecycle. CSA delivers visibility into what is currently in production, what’s been changed, and the status of outstanding requests—supporting operational decisions and regulatory audits.
Configuration auditing verifies that actual system states match documented configurations and approved baselines. There are two primary types: Functional Configuration Audits (FCA) and Physical Configuration Audits (PCA). Audits ensure compliance, detect unauthorized changes, and support quality assurance.
A Configuration Management Plan (CMP) is a formal document outlining how configuration management will be performed for a project or organization. The CMP defines scope, processes, roles, tools, integration points, and compliance requirements, and is updated as the project evolves.
Configuration management is integral to systems engineering, ensuring that all components (hardware, software, documentation) are identified, controlled, and traceable from requirements through retirement. This discipline supports interoperability, risk management, and lifecycle sustainment, and is mandated by standards such as ISO/IEC 15288 and ANSI–EIA–649.
Airlines use configuration management to track aircraft software versions, hardware components, and documentation, ensuring compliance with EASA/FAA regulations and supporting rapid incident response.
DevOps teams manage infrastructure and application configurations using Git and IaC tools, enabling automated, auditable deployments and rapid rollback in case of issues.
Complex systems (e.g., satellites or defense platforms) use configuration management to ensure that every component is traceable to its requirements, supporting integration, maintenance, and certification.
Configuration management is a foundational discipline for organizations in regulated, complex, and safety-critical environments. By establishing robust processes, leveraging automation, and maintaining a single source of truth, organizations can achieve operational excellence, minimize risk, and ensure compliance with industry standards.
Configuration management is critical in aviation and IT because it ensures that system changes are systematically controlled, traceable, and compliant with stringent regulatory requirements. In aviation, this is essential for maintaining airworthiness and safety, while in IT, it minimizes risk, prevents configuration drift, and supports reliable service delivery.
The core components are Configuration Identification, Change Control, Status Accounting, Auditing, and Baselines. Together, these elements ensure that all configuration items (CIs) are identified, tracked, controlled, and verifiable throughout their lifecycle.
A CMDB provides a centralized repository for all configuration data, enabling organizations to track assets, manage dependencies, analyze changes, and ensure compliance. It is foundational to effective change management, incident response, and regulatory audits.
A Configuration Item (CI) is any asset or component managed in the system, such as hardware, software, or documentation. A baseline is a formally approved snapshot of the configuration at a specific point in time, used as a reference for future changes or restorations.
Configuration management underpins DevOps and Agile by ensuring that infrastructure, code, and configurations are versioned, reproducible, and traceable. Practices like Infrastructure as Code (IaC) and CI/CD rely on robust configuration management for reliable, automated deployments.
