Release management is the process of optimizing all stages of launching a software product or feature. As enterprise software delivery becomes faster and more complex, release management is essential to meet deadlines without sacrificing quality.  

For software development teams, a thorough release management plan is the difference between a smooth launch and a frantic scramble where you’re putting out fires all day.

In this article, we’ll outline the five phases of releasing software, explain the essential roles in the process, and share best practices for a successful launch. 

Four broad best practices of release management are:

  1. Standardize what success looks like
  2. Dark launch with feature flags to reduce risk
  3. Automate, but do it safely
  4. Track metrics early and often

Before unpacking each best practice, let’s cover the basics of release management.

What is release management?

Release management (sometimes called deployment management) is the system that helps you control the entire software development life cycle—from planning to testing to release. It’s the framework that keeps your team on track so you can ship fast and rest easy.

Release management is geared toward five goals: 

  1. Mitigate risk throughout the software delivery life cycle (SDLC)
  2. Align all teams involved in the release
  3. Streamline the development and release processes
  4. Meet deadlines consistently
  5. Align development goals with business goals

Whether you’re examining release management through the lens of ITIL (IT Infrastructure Library) or DevOps, the end goal is the same. The main difference is that in ITIL, IT operations teams tend to work in a silo while in DevOps, all teams collaborate from the beginning—this enables shorter feedback loops and faster releases. Deployment processes, of course, differ between teams employing Agile vs. Waterfall methodologies. In this article, we’re promoting an approach to software release management that aligns with modern DevOps practices and enables teams to achieve Continuous Integration and Continuous Delivery (CI/CD).

The specifics of release management will vary depending on your unique needs. But before we dive into the details, let’s outline the five phases of a software release.

5 phases of a software release

Most development processes can be broken down into these five key phases.

1. Define specific requirements for the release

Let’s say you’re planning a new release within an existing software product: a one-click checkout feature. One requirement might be that this new version is functional on both desktop browsers and mobile devices.

2. Specify your acceptance criteria

Based on the requirements you defined in step one, you’ll set testable standards for each one. Continuing with our one-click checkout example, acceptance criteria might include:

  • New feature displays correctly on iOS
  • New feature displays correctly on Android OS

3. Test your software in production

Traditionally, software teams push their product to a test or staging environment that replicates a real production environment. But a more reliable (and less risky) method for testing products is by dark launching (i.e., testing in production), which lets you release features to a small group of real users prior to a full release. The best way to dark launch is with feature flags, which enable or disable functionality remotely without deploying code.

If you dark launched the one-click checkout feature, you would enable it for 1% of your end-users, then 5%, and 10%, etc., tracking performance along the way.

4. Iterate and refine your product 

Throughout the release process, keep a close eye on user response and KPIs to decide whether the feature should be rolled out to a wider audience. If the feature doesn’t catch on, degrades your app’s performance, or doesn’t meet your acceptance criteria, the feature should be rolled back and refined.

5. Release your product to end-users

After sign-off from your quality assurance (QA) team, it’s time to go live. Note: if you’re dark launching, feature flags let you separate software deployment from software release. This allows developers to ship code to a production environment, after which a product manager can release that code to end-users at the right time. 

This decoupling of deployment from release allows companies to set the pace and give customers time to adapt. It’s also an effective way to align your software release policy with your change management and configuration management policies. Lastly, it increases developer productivity by a wide margin.

Key roles in the release management process

As development teams are under pressure to roll out new features faster and more frequently than ever, having the right personnel in place is critical for your release management strategy. 

Let’s take a closer look at the following pivotal roles and what each one is responsible for:

Release manager

A release manager sets the pace for software rollouts and ensures customers have all the resources they need. Additionally, they are responsible for getting all stakeholders in sync—from leadership to operations teams—to ensure a successful release. They also may oversee the creation of training materials for customers.

Product owner

The primary responsibility of this role is establishing the requirements and acceptance criteria we mentioned in the previous section. Product owners are the bridge between the product and the business. 

Quality manager

As the title implies, the quality manager oversees testing to determine whether software passes acceptance criteria without false positives or negatives.

DevOps team

In release management, the DevOps team controls the entire lifecycle of a feature from design to development to production support.

4 software release management best practices

There is no one-size-fits-all approach when it comes to release management, but you can ground yourself in principles that apply to all teams.

1. Standardize what success looks like

Relying on subjective feedback to evaluate your release is ineffective. Instead, establish key performance indicators (KPIs) that can be objectively tracked—whether that’s a number of downloads or an error rate. Standardizing success ensures all of your team members stay on the same page.

2. Dark launch with feature flags to reduce risk

Rolling out new software to a massive user base all at once is a risky move. One glitch can unravel all the hard work you’ve done. Dark launching, on the other hand, lets you test new features on 1% (or less) of your users instead of 100%. As we mentioned earlier, the most efficient way to dark launch is with feature flags that let you turn functionality on or off with one click.

Here are three ways dark launching with feature flags flattens your risk profile:

  1. Starting small and scaling up to larger groups lets you observe the software under increasing load. Going from 0 to 100 can present extreme risks for DevOps teams—and users. But dark launching with a feature management platform like LaunchDarkly allows you to release a feature gradually, thus minimizing the negative impacts of a production bug.
  2. Dark launching allows you to release a new feature to a small custom user group (i.e., a canary group). This means you can hand-pick a group of users who have a higher risk tolerance than, say, users from heavily regulated industries like finance or government. Thus, if the new feature causes errors, you’re not only shrinking the number of users affected by the errors, but you’re also restricting the effects to people who will be more gracious than other users about the buggy feature. 
  3. Feature flags can act as a “kill switch” if something goes wrong in production. This allows you to respond to incidents quickly and minimize the blast radius of the error.

3. Automate, but do it safely

Automation (when implemented correctly) reduces human errors and frees up your team to spend more time on creative, high-impact projects. LaunchDarkly’s Feature Workflows was built to automate manual tasks throughout the software release process for teams of any size. 

Here are two key automating features:

  1. “Set and forget” releases: schedule future releases for a specified date or time. No more setting reminders or waking up early to turn on a feature flag. Not only that, with Feature Workflows, you can schedule the automatic removal of feature flags from your codebase after a feature has reached general availability (GA), thus reducing technical debt.
  2. Release progressions (progressive rollouts): define the release cadence that suits your team’s needs, then sit back and relax. For example, you can schedule your flag to automatically release to 20% of users tomorrow, 35% the day after, and increase gradually to 100%. And if at any point, the new feature causes a critical service issue, LaunchDarkly will automatically halt the rollout and disable the feature.

4. Track metrics early and often

You can’t improve what you don’t measure. Make sure to set up monitoring to track your software’s performance before, during, and after your release. These metrics can include, but aren’t limited to load time, error rate, downtime, uptime, conversions, and opt-ins. When releasing new features, you can also run experiments and track metrics on those features with LaunchDarkly’s Experimentation Add-on. And you can export experimentation data and feature flag metrics to any analytics tool of your choosing via LauchDarkly’s Data Export Add-on.

Equip yourself with the right release management tools

With the rise of Continuous Integration and Continuous Delivery, DevOps teams are under pressure to speed up the release cycle without sacrificing quality. A good release plan helps you achieve both, but you need the right tools to make it happen.
