Test Environments – The Tracks for Agile Release Trains
by Niall Crawford & Justin Reynolds.
Modified by Eric Goebelbecker.
Definition: An Agile Release Train is several teams (a portfolio) responsible for the regular release of features and business benefits. All the teams share a common set of goals, a program backlog, and a roadmap. ART is central to understanding and implementing a Scaled Agile Framework.
And why not? An Agile Release Train (or Enterprise Release Management) methodology is better than the alternative chaos of different project teams running off in different directions. This approach leads to competition for shared resources, misaligned priorities, and delays due to mismanaged dependencies & relationships with other teams.
If implemented correctly, ART will help IT deliver on business transformations as quickly and safely as possible and deliver timely solutions into production and to the end customers.
So, we get started with each team loading up the train carriages with features & change requests. Then, we start our journey toward production.
…and the proverbial “wheels fall off”.
We often see delays in Development, System Test, Integration, UAT & Staging due to test environment:
- instability due to unplanned changes
- systems don’t meet requirements
Suddenly the ART journey looks like something out of “Thomas the Tank Engine.”
Whether real or agile, the problem with trains is they need a track. Delays and collisions are inevitable if the tracks (or the stations) are inappropriately sized, incorrectly built, mismanaged, or overfilled.
In the case of your Agile Release Trains, imagine the train stations as your lifecycle. The ART will travel through each station (Development, System Test, Integration, UAT & Staging) to allow the necessary onboarding of fixes (good commuters) & offboarding of defects (bad commuters).
If you lack robust testing capabilities, your train will face the following problems:
Environment contention can create internal conflict and impede collaboration, slowing down timelines and making it harder to reach your goals.
Lack of Visibility
IT leaders typically have limited transparency into data and configurations across test environments. The vast majority of companies have no idea what their end-to-end IT and test environments look like.
Unfortunately, this lack of visibility makes it impossible to track progress, manage workflows, and improve outcomes.
IT environments often contain large volumes of sensitive data. Yet organizations tend to be lax about security privacy guidelines in test environments. This puts sensitive data at risk, leading to costly incidents, reputational damage, and other penalties.
For testing environments to be effective, managers need deep visibility into testing and performance data.
Traditional testing solutions often lack comprehensive reporting components. As a result, teams have a hard time generating a complete picture of what’s taking place at any given time.
It’s easy to miss a step during testing. When that happens, the analysis is incomplete. It drives up the time and cost of system deployments and thwarts go-to-market plans.
Maintaining the Track
In IT, preparing the track is analogous to your IT and Test Environment Management, and if your test environments aren’t ready, you’ll never get out of the station.
One easy way to assess your environment is by using the Environment Management Maturity Index Assessment (EMMi). The EMMi can help you gain a basic understanding of your testing environment.
Start by rating yourself across the following EMMi categories to see where you stand.
1. Environment Knowledge Management
How well do you understand your IT environment across all touchpoints in detail? Surprisingly, many teams don’t know as much as they should.
2. Environment Demand Awareness
Consider whether you have a grasp on demand and current usage of your IT environments. While you’re at it, think about how well your teams coordinate testing.
3. Environment Planning and Coordination
This step involves assessing configurations and deployments across all systems.
4. Service Management
Next, assess how your organization tracks incidents, changes, and releases.
5. Application Release Operations
Is your organization implementing consistent, repeatable, and traceable application releases? This step generally explores how well you’re promoting standard operating procedures.
6. Data Release and Privacy Operations
What’s more, you need to determine whether your team can ensure consistent and reliable data releases.
7. Infrastructure and Cloud Release Operation
Does your team have consistent and repeatable infrastructure and release operations? Take a moment to consider your release operating procedures and your infrastructure policies.
8. Status Accounting and Reporting
How well does your team capture and present real-time environment data? Consider your ability to visualize environment topology, usage, activities, health, operational behavior, and system team competence.

Effective Test Environment Management Helps ART
After bad requirements management, Test Environments are the number one reason for project delays. Hardly surprising when you consider that is where projects spend most of their time.
By implementing a proper TEM framework, you ensure:
- Environments Readiness (systems prepared in advance)
- Environments Suitability (systems fit for purpose)
- Environment Stability (disruption/outage avoidance)
- Release Team Productivity (more time to Develop & Test)
- Release Streamlining (Maglev style) &
- Reduced IT Costs through better project sharing & post-release housekeeping
So next time someone mentions the ART, ask them about the readiness of the tracks. As trains don’t go too far without them.
