SCM Processes

Software Configuration Management (SCM) involves a set of processes that ensure the effective management of software artifacts, from planning and development to deployment and maintenance. These processes help track and control changes, ensuring the consistency, integrity, and traceability of the software throughout its lifecycle.

Key SCM Processes:

• Configuration Identification: This process involves defining and documenting all software components, including code, documentation, libraries, and configuration files. Each component is uniquely identified and versioned to track its changes over time.
• Version Control: Version control is used to manage different versions of software artifacts. It allows teams to track changes, maintain historical records, and revert to earlier versions if necessary. Common tools like Git or SVN are used in this process.
• Change Control: Change control ensures that changes to the software are systematically reviewed and approved. This process helps minimize disruptions, ensures that changes are well-documented, and prevents unauthorized modifications an approach often discussed when comparing a Software Engineering Degree vs Computer Science.
• Configuration Auditing: Configuration auditing ensures that the software system adheres to the established standards, requirements, and specifications. It involves regular checks to confirm that the software components are correctly configured and meet quality standards.
• Build Management: This process automates the creation of software builds by ensuring that the right versions of components are used and that dependencies are correctly managed. It helps to create consistent and reproducible software builds.
• Release Management: Release management involves planning, scheduling, and controlling the deployment of software versions. It ensures that the right software configurations are released into the appropriate environments and that deployment is smooth and error-free.
