Test Environments – Oiling the Tracks for Agile Release Trains
Once the train leaves the station, there's no going back. So make sure you are aware of how to prepare for the duration of the project with these ART elements.

Definition: An Agile Release Train is basically a number of teams (a portfolio) responsible for the regular release of features and business benefits. All the teams are bound by 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 usually much better than the alternative chaos of different project teams running off in different directions (as “fast” as they can), competing for shared resources (service & systems), misaligning group priorities and ultimately causing collective delivery delays due to mismanaged dependencies & relationships with other teams.
If implemented correctly, ART will help IT deliver on the necessary IT business transformations as quickly and safely as possible, and ultimately deliver timely solutions into production and to the end-customers.
Key Benefits of the Agile Release Train
- Increased Collaboration
- Improved Change (Feature) Throughput
- Controlled Velocity
- Cross Team Productivity
- Risk Cognizance / Awareness
- Circumvent Release Failure
- Delivery Streamlining
So, we get started by each team loading up the train carriages with Features & Change, and we collectively commence out journey towards production.
Then the proverbial “wheels fall off.”
Delays in Development, System Test, Integration, UAT & Staging due to:
- Test environment unreadiness, i.e. engineering team are still building it.
- Test environment contention, i.e. BAU Team currently has it.
- Test environment instability due to too much unplanned change
- Test environment systems are not fit for purpose, e.g. wrong scale or version or integrations
And the risk of overspending, for example:
- Need for more systems (infrastructure & licensing) to address contention
- Need for more support (services) to accelerate tasks & remediate
And suddenly our ART suddenly look like something out of “Thomas the Tank Engine”.
The problem with trains, whether real or agile, is they must follow a rail track and delays & collisions will be inevitable if tracks (or the stations) are inappropriately sized, incorrectly built, mismanaged, and not kept clear.
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 on-boarding of fixes (good commuters) & offboarding of defects (bad commuters).
Oiling the Track
In IT, preparing the rail track is analogous to the task of IT & Test Environment Management. A multi-faceted set of discipline, exemplified in the EMMI (Environment Management Maturity Index), ensures appropriate:
Benefits to ART of Implementing Effective Test Environments Management
After bad requirements management, Test Environments are the number one reason for Project delays. Hardly surprising when you consider that is where projects (and I guess Agile Release Trains) spends 95% of their time.
By implementing a proper TEM framework (tracks), 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.
