Its value is not the number of tests a team runs: it is whether trustworthy checks find important problems early enough to make releases safer and less disruptive.
Why automated testing belongs on a leadership agenda
Testing is a delivery capability, not simply a final quality gate. When teams leave regression checks until development is declared complete, manual checking can slow releases, repetitive work can be error-prone, and defects found late can take more effort to triage and fix. DORA’s test automation guidance recommends continuous testing and fast feedback throughout the software delivery lifecycle.
That feedback helps teams learn whether a change has affected important behavior while the change is still relatively easy to investigate. DORA’s guidance associates effective test automation with building quality faster, improved software stability, reduced team burnout, and lower deployment pain. These are research-based associations, not guaranteed outcomes for every team or a promise of a particular financial return.
DORA describes the goal of continuous delivery as reducing software risk. Its continuous delivery guidance identifies fast feedback on quality and deployability as a core practice and test automation as one of the technical capabilities that support it.

What automation changes—and what it does not
Automated checks can run repeatedly and consistently when code changes or a delivery pipeline is triggered. That makes them useful for catching regressions in well-defined behavior without asking people to repeat the same checks by hand on every change.
Automation does not replace human judgment. Exploratory testing can uncover unexpected problems; usability testing assesses experiences that are difficult to reduce to fixed assertions; and people still need to assess whether software meets acceptance needs. DORA recommends testing as a set of activities throughout delivery, with developers and testers working alongside one another rather than treating testing as a separate final phase.
| Approach | Strength | Trade-off to manage |
|---|---|---|
| Late or manual-only regression checking | People can exercise judgment and investigate behavior in context. | Feedback arrives later, repetitive checks consume time, and late-found defects can be harder to diagnose. |
| Continuous, mixed-mode testing | Automated checks provide repeatable feedback during delivery, while people explore, assess usability, and judge acceptance. | Teams must invest in testability, reliable automation, and ongoing maintenance; noisy tests can undermine trust. |
What leaders can enable
Put feedback into the delivery flow
Support teams in running reliable automated checks locally and in delivery pipelines, rather than waiting for a final testing phase. DORA’s test automation guidance calls for local and continuous-integration feedback in less than ten minutes. Treat that as guidance from DORA, not a universal service-level requirement; teams should account for their systems and constraints.
Use the right checks for the question
Unit tests are suited to narrow, fast feedback. Acceptance tests check important higher-level behavior against business acceptance criteria. Protect high-value functionality, and seek a maintainable balance: DORA does not prescribe one fixed unit-to-acceptance test ratio.
Keep human testing in the plan
Reserve time and skills for exploratory, usability, and acceptance work. These activities help teams find issues that fixed automated checks may not express or anticipate.
Maintain a suite people trust
Review test suites regularly. Investigate flaky checks and failures that do not correspond to real product defects, and prune tests that are expensive to maintain or no longer trusted. A large suite that produces noise can be less useful than a smaller, dependable one.
Turn late discoveries into earlier learning
When a defect escapes to a slower test stage or production, consider whether a faster, earlier check could have caught it. Add that check where it makes sense, while keeping the overall suite understandable and maintainable.
How to tell whether testing is working
Measure whether testing improves feedback and defect discovery, not just how many tests exist. DORA’s test automation guidance suggests tracking these signals over time:
Best Value
- The proportion of defects found during acceptance testing, exploratory testing, and production. A shift toward earlier discovery can indicate that checks are catching problems sooner.
- Time spent resolving acceptance-test failures, which helps show how much investigation and repair those failures require.
- Whether automated failures point to real product defects or to poor test code. This is a practical signal of how much teams can trust the suite.
- Whether test suites run on delivery-pipeline triggers, rather than relying only on occasional or manual execution.
Pair these testing signals with delivery and service outcomes that matter to your organization. Define any measures you use and interpret them in the context of your system, release process, and regulatory obligations. Test count or code coverage alone does not show whether tests find consequential defects or remain reliable and affordable to maintain.

Automation takes organizational and technical investment, including making software testable and maintaining the suite as the product changes. DORA’s guidance supports using testing to build quality and reduce delivery risk, but it does not establish a universal return on investment, defect-reduction percentage, or release-speed gain attributable to automation alone. A sensible leadership case is to improve the feedback loop and watch whether the organization finds problems earlier, resolves failures more efficiently, and can rely on its checks.
Continuous delivery is also distinct from continuous deployment. Continuous delivery means keeping a system ready to release on demand; continuous deployment automatically releases changes. The latter does not suit every software context. DORA says continuous delivery can apply across contexts, including regulated environments, while practices should fit the system and its requirements.
