What Is Version Control?
Software teams have been using version control for many years. But depending on your industry, you might be new to the concept. Version control started with software development. Today, version control can be used for both hardware and software product development.
So, What Is Version Control?
Version control allows you to manage changes over time. You can track revisions of your project’s assets. This includes source code, graphics (2D/3D for game and product development), movies, audio, analog and digital semiconductor designs, or any other type of digital asset.
Version control is sometimes referred to as revision control or source control. It’s an important component of software configuration management.
And Why Is Version Control Important?
Version control is important for today’s development teams. It needs to do more than just manage and track files. It should help you develop and ship products faster. This is especially important for teams practicing DevOps.
That’s because using the right version control:
- Improves visibility.
- Helps teams collaborate around the world.
- Accelerates product delivery.

Types of Version Control
There are several types of version control systems that teams use today. Here are a few of the most common ones.
Example: Version Control With Perforce
Growing development teams around the world use Perforce — Helix Core — for version control. Helix Core is a smart choice for globally distributed development teams, as well as teams working on complex products. Using Helix Core also helps teams manage all of their product development activities.
Example: Version Control With Git
Many developers use Git for version control. Version control with Git can be a good option for small teams, especially those working on web and mobile application development.

Example: Version Control With SVN
Version control with Subversion (SVN) used to be one of the most popular options. However, many teams have outgrown SVN and are looking for options that can scale with them.

Top Version Control Benefits and Features
Each version control system comes with different benefits and features. What matters most will depend on your team’s needs.
Here are five of the top things that today’s development teams are looking for in version control.
1. Concurrent Development
Projects are getting more complex. There’s a growing need to manage multiple versions of source code files — and entire products.
This means multiple developers and designers can work on the same set of files — without worrying that they are duplicating effort or overwriting other team members’ work.
Let’s say you're managing an IOT deployment for high-end internet-connected security cameras. Over the product lifecycle, you may use ten different types of cameras, each with a different chip. As a result, each will have different software.
Using the right version control means you can maintain multiple versions of your code to manage the specific functionality of each camera's chip and operating system.
So, when you need to deploy a critical security patch to prevent bad guys from hijacking those cameras, it’s easy. You’ll instantly see which code is impacted, make the changes, and deploy a fix.
Higher quality and increased productivity are top priorities for today’s development teams. And your team can reach your goals by automating tasks, such as testing and deployment.
In software development, Continuous Integration (CI) with automated builds and code reviews are a standard operating procedure.
For hardware development, such as semiconductors, automation can include:
- Testing with field programmable gate arrays (FPGAs).
- Integration with simulation verification and synthesis systems.
Such FPGAs or verification and testing systems must themselves be controlled and versioned, along with potentially very large data files. It is vital that even small changes are tracked and managed. This means your version control system is the center of the IP universe. The right version control system can handle millions of automated transactions per day with millions of files.
3. Team Collaboration
Companies operate where the talent lives. This means you might have design and development centers in Minneapolis, Seattle, Toronto, and Shanghai. And when deadlines loom, you might need to add engineers in Paris and possibly even in Taipei.
You need a way to provide global access to your team members at all your facilities. Having a single source of truth –– with appropriately secured identity and access management –– is critical for your success.
With the right version control, each team member is working on the latest version. And that makes it easier to collaborate.
4. Tracked Changes — Who, What, When, Why
Every development team needs visibility into changes. Tracking who, what, when, and why changes are made is important.
Version control captures this detailed information and maintains this history forever. So, everyone gets access to who is working on what — and the changes that are made
This is especially important if you have governance, risk, and compliance (GRC) or regulatory needs. Audit log history is especially key in the automotive, aerospace, medical device, and semiconductor industries.
5. High Availability/Disaster Recovery
The most expensive asset you have is your product development team. You can't have them idled because they've lost access to the code.
With the right version control system, you can have a replica of your enterprise repository –– your single source of truth –– operating in another location. If something happens, you can immediately switch over to a replica of the master for uninterrupted availability.
Getting Started With Version Control
Using the right version control software — like Helix Core — helps your development team work simultaneously, automate tasks, track changes, and ensure high availability/disaster recovery.
Get started with version control for free. Helix Core is always free for up to 5 users and 20 workspaces.
