Version Control

• Version Control, also known as Reversion Control, is a system that keeps track of changes made to a set of files over time. It allows multiple people to work on the same files simultaneously, and keeps a record of every change that is made. This makes it easy for users to go back to previous versions of the files, or to see who made a particular change.

• In the design process, revision control is important for several reasons:

  • Collaboration: It allows multiple team members to work on the same design files at the same time, making it easy to see who made what changes and when. This facilitates the collaboration among the team members, and makes it easier to resolve conflicts when they arise.

  • Traceability: Version control systems maintain a history of changes made to the design files, so it is easy to trace any changes made and the person who made them. This is useful for auditing, reviewing, and debugging the design.

  • Backup and Recovery: Version control systems keep a copy of each version of the design files, making it easy to go back to a previous version if something goes wrong. This can be helpful in case of human error, or if the design needs to be restored to a previous point in time.

  • Compliance: In regulated industries, like aerospace, automotive, medical devices, etc, revision control is essential to ensure compliance with regulations and standards. It's important to be able to track and prove the history of design changes, and that they have been reviewed, approved, and properly implemented.

  • Experimentation: Version control also allows for experimentation with different design alternatives and to switch between them easily, by creating branches, this allows for testing different versions of the design and select the best one.

• Different industries and organizations may have different standards for properly documenting Revision Control of designs, but some general practices to follow include:

  • Use a Consistent Numbering System: It's important to have a consistent numbering system for version control. A common practice is to use a version number in the format of "major.minor.patch" (e.g. 1.0.0, 2.1.3). The major version number is incremented when there are significant changes or new features added to the product, the minor version number is incremented when there are minor changes or bug fixes, and the patch number is incremented when there are only small bug fixes or updates.

  • Keep Detailed Release Notes: It's important to keep detailed release notes for each version of the product. The release notes should include a detailed list of changes made in that version, as well as any known issues or limitations.

  • Use Branches and Tags: Use branches to create different versions of the product, and tags to mark specific versions. This allows for easy switching between different versions and experimentation with different design alternatives.

  • Limit the Number of Branches: Avoid creating too many branches, as it can make it difficult to keep track of changes and merge them. Limit the number of branches to only the most important ones, like "master", "development", "release" branches.

  • Use a Version Control System: Use a version control system, like Git, SVN, or Mercurial, to keep track of changes made to the product. These systems allow for easy collaboration, tracking, and rollback of changes.

  • Follow Naming Conventions: Use naming conventions for branches and tags, like "v1.0", "v2.0", "release", "feature/...", etc. This will make it easy to identify the different versions of the product.

  • Track and Review Changes: Use the version control system to track changes, and ensure that all changes are reviewed and approved before being committed to the repository. This will help to ensure the quality and consistency of the product.

• By following these guidelines, you can effectively manage and track changes to your product, ensure consistency and quality, and make it easy to switch between different versions and experiment with different design alternatives
