As technology expands, so does software complexity and, oftentimes, the number of people working on a software project. Source code management (SCM) is a process software teams can use to easily manage work progress and track modifications to source code.
Source code management has great benefits for software engineering teams. First, it helps to easily manage their work progress. Source control strategies allow software teams to track their work, ensuring they can roll back changes and navigate between code versions quickly and seamlessly.
If you are working on an embedded software or other software project with a team, no matter how big or small, you will likely need to put your work together at some point. Source code management supports communication and collaboration across the team and enables team members to merge their work with minimal effort and conflicts.
To make your source code management process the best it can be and meet the needs of your project, there are some source control best practices to follow.
Create a branching policy. To ensure source code management success, the software engineering team should create and follow a well-defined branching policy. In source code management, the whole team is working on the main line code, often referred to as the trunk. A member of the team could create a branch for any number of reasons – to work on a feature, fix a bug, or try out some experimental code. Some teams will branch for the purpose of testing an upcoming release, allowing for managed change if issues are identified. Some other things to consider in your source code management branching policy include:
Ensure traceability. When committing an item to the repository, make sure it is traceable. The easiest way to do this is to use a version control tool and an application lifecycle management tool. This traces each patch or code change to a specific request in the application lifecycle management tool, then to requirements, and ultimately a change request, giving you full traceability.
Manage commits properly. It is critical to keep commits small, make sure they happen one at a time, and focus on a single change or responsibility. If you do, and one of the commits doesn’t work or breaks the build’s functionality, you can selectively pull the offending change. This will maximize your effort and improve your efficiency.
Write thorough commit messages. Make sure you are explaining your intentions when committing to the repository. The most useful commit message refers to an item in the application lifecycle management tool, giving you the entire history and full traceability.Source code management can help your software teams work better and more efficiently, culminating in a better product.
